I am retrieving appoints from an exchange server using the service.FindItems method and it isn't returning recurring appointments. It returns the first instance of recurring items but no more after that and IsRecurring is set to false on the appointment.
This is the code:
private void loadUsersAppointments(string user, int rscID)
{
// Add a search filter that searches on the body or subject.
List<SearchFilter> searchFilterCollection = new List<SearchFilter>();
searchFilterCollection.Add(new SearchFilter.IsGreaterThan(AppointmentSchema.Start, DateTime.Today.AddDays(-7)));
// Create the search filter.
SearchFilter searchFilter = new SearchFilter.SearchFilterCollection(LogicalOperator.Or, searchFilterCollection.ToArray());
CalendarView V = new CalendarView(DateTime.Today.AddDays(-7), DateTime.Today.AddMonths(1), 1000);
V.PropertySet = new PropertySet(BasePropertySet.IdOnly, AppointmentSchema.Subject, AppointmentSchema.Start, AppointmentSchema.End);
V.Traversal = ItemTraversal.Shallow;
// Create a view with a page size of 50.
ItemView view = new ItemView(10000);
// Identify the Subject and DateTimeReceived properties to return.
// Indicate that the base property will be the item identifier
view.PropertySet = new PropertySet(BasePropertySet.IdOnly, AppointmentSchema.Subject, AppointmentSchema.Start, AppointmentSchema.End);
// Order the search results by the DateTimeReceived in descending order.
view.OrderBy.Add(AppointmentSchema.Start, SortDirection.Descending);
// Set the traversal to shallow. (Shallow is the default option; other options are Associated and SoftDeleted.)
view.Traversal = ItemTraversal.Shallow;
// Send the request to search the Inbox and get the results.
ExchangeService service = GlobalFunc.ElevateGetBinding();
service.ImpersonatedUserId = new ImpersonatedUserId(ConnectingIdType.SmtpAddress, user+"#works.local");
FindItemsResults<Item> findResults = service.FindItems(WellKnownFolderName.Calendar, searchFilter, view);
List<Item> items = new List<Item>();
foreach (Microsoft.Exchange.WebServices.Data.Appointment appointment in findResults)
{
items.Add(appointment);
}
service.LoadPropertiesForItems(items, PropertySet.FirstClassProperties);
// Process each item.
foreach (Microsoft.Exchange.WebServices.Data.Appointment myItem in items)
{
DevExpress.XtraScheduler.Appointment AddAppt = new DevExpress.XtraScheduler.Appointment();
try {
if (myItem.Subject.StartsWith("Advisor Appointment"))
AddAppt.LabelId = 8;
else
AddAppt.LabelId = 2;
AddAppt.Subject = myItem.Subject;
}
catch { }
try
{
}
catch (Exception ex) { MessageBox.Show(ex.Message); }
try { AddAppt.Start = myItem.Start; }
catch { }
try { AddAppt.Description = myItem.Body; }
catch { }
try { AddAppt.End = myItem.End; }
catch { }
AddAppt.ResourceId = rscID;
schStorage.Appointments.Add(AddAppt);
}
}
Any ideas would be much appreciated.
Thanks
You need to use a CalendarView to get recurring appointments. Instances of recurring appointments are not real items in the Exchange database. Instead, Exchange creates virtual items on the fly when you query for a specific time range.

Essentially what the title says, for whatever reason when I call clientContext.ExecuteQuery(); and for example the list the data is going into has a missing column, I don't get an exception, it actually just runs as expected and I have to go and investigate what might have caused the data to not appear.
The NuGet package i'm using is Microsoft.SharePoint2016.CSOM version 16.0.4690.1000
Any hints, or suggestions to point me in the right direction appreciated. It's entirely possible I'm being a bit dim here.

I checked the code you posted and I see that you are updating the list of objects, in your case listItems, instead of a ListItem in ListItemCollection, in your case listItemCol.
To be more clear, I believe you can try to replace listItems with listItemCol.
For instance, instead of:
listItems[existingItemIndex].ParseAndSetFieldValue(keyValuePair.Key, keyValuePair.Value);
use
listItemCol[existingItemIndex][keyValuePair.Key] = keyValuePair.Value;
So I went away and re-read a lot of documentation and looked over some examples, and I wondered why the exception handler never returned errors even though it's obvious there were issues with the query being executed. If you look at the Microsoft documentation and their example here you'll see that they don't show you how to use exceptionScopeSubmit.HasException component of the exception scope object. Which lead to a really stupid assumption on my part. It turns out that the exception block runs on the SharePoint server and should be used to fix issues you might have caused during an expected exception in your query.
Not only that but wrapping the ExecuteQuery in the try catch is redundant when using an exception scope as it means that method will no longer throw an exception. You actually have to assess exceptionScopeSubmit.HasException after the execution to pull back some more detailing information on errors reported by the SharePoint server side execution of your query.
So now I'm using it as below, and I can get detailed error information without having to do some stupid manual debugging which would easily take me hours to track down silly issues. So in case anyone stumbles across this having the same issues, I hope it helps.
ExceptionHandlingScope exceptionScopeFetch = new ExceptionHandlingScope(clientContext);
// variables.
IntegrationEventLog log = new IntegrationEventLog();
EventInformation ei = new EventInformation();
List list = null;
ListItemCollection listItemCol = null;
using (exceptionScopeFetch.StartScope())
{
using (exceptionScopeFetch.StartTry())
{
// get the required list
list = clientContext.Web.Lists.GetByTitle(definition.ListName);
// create query
listItemCol = list.GetItems(CamlQuery.CreateAllItemsQuery());
// set these items for retrieval.
clientContext.Load(listItemCol);
}
using (exceptionScopeFetch.StartCatch())
{
//
}
using (exceptionScopeFetch.StartFinally())
{
//
}
}
// get item instances first
clientContext.ExecuteQuery();
if (exceptionScopeSubmit.HasException)
{
ei = new EventInformation()
{
LoggingEventType = LoggingEventType.DataSentFailure,
LoggingSeverity = LoggingSeverity.HighSeverity,
SerialisedMessage = JsonConvert.SerializeObject(definition),
ServiceMessage = $"Error at SharePoint exception handler during submit to list: Message: {exceptionScopeFetch.ErrorMessage}",
StackTrace = exceptionScopeFetch.ServerStackTrace,
TimeGenerated = DateTime.Now,
TimeWritten = DateTime.Now,
};
log.EventLogEntryType = EventLogEntryType.Error;
log.EventID = LoggingSeverity.HighSeverity;
log.Message = JsonConvert.SerializeObject(ei);
AddToLog(log);
}
I am able to retrieve all the emails and log them but I can't seem to get the body to just be plain text. I've tried looking at other examples on here but I can't seem to grasp the problem. Below is my code so far:
//retrieve emails in blocks of 50
int offset = 1;
int pageSize = 50;
bool moreEmails = true;
ItemView view = new ItemView(pageSize, offset, OffsetBasePoint.Beginning);
view.PropertySet = PropertySet.IdOnly;
while (moreEmails)
{
findResults = service.FindItems(WellKnownFolderName.Inbox, view);
foreach (var item in findResults.Items)
{
emails.Add((EmailMessage)item);
}
moreEmails = findResults.MoreAvailable;
if (moreEmails)
{
view.Offset += pageSize;
}
}
PropertySet properties = new
PropertySet (BasePropertySet.FirstClassProperties);
service.LoadPropertiesForItems(emails, properties);
properties.RequestedBodyType = BodyType.Text;
I'm initialising the variables in a separate function:
private static void CheckRules()
{
try
{
foreach (var EmailParam in emails)
{
FromEmail = EmailParam.From.Address.ToString();
EmailDate = EmailParam.DateTimeReceived.ToString("yyyy-MM-dd hh:mm:ss");
EmailSubject = EmailParam.Subject.ToString();
EmailBody = EmailParam.Body.Text.ToString();
etc...
So again, I just want the body to be plain text. Thanks in advance for any help!
I am trying to fetch email body from exchange server for an appointment for a particular room but did not get a success. Verified all the blogs over internet but nothing was of any help. Here is the code where i am trying to contact exchange server to get the details:
Approach A
service.GetUserAvailability
(
attendees,
new TimeWindow(twStart, twEnd),
AvailabilityData.FreeBusy
).AttendeesAvailability[0].CalendarEvents;
Approach B
public class MailItem
{
public string From;
public string[] Recipients;
public string Subject;
public string Body;
}
public static MailItem[] GetUnreadMailFromInbox(ExchangeService service, string address)
{
// Address is the email address for an meeting room
try
{
service.ImpersonatedUserId = new ImpersonatedUserId(ConnectingIdType.SmtpAddress, address);
FindItemsResults<Item> findResults = service.FindItems(WellKnownFolderName.Inbox, new ItemView(128));
ServiceResponseCollection<GetItemResponse> items =
service.BindToItems(findResults.Select(item => item.Id), new PropertySet(BasePropertySet.FirstClassProperties, EmailMessageSchema.From, EmailMessageSchema.ToRecipients));
FindItemsResults<Item> findResults2 = service.FindItems(WellKnownFolderName.Calendar, new ItemView(128));
ServiceResponseCollection<GetItemResponse> items2 =
service.BindToItems(findResults2.Select(item2 => item2.Id), new PropertySet(BasePropertySet.FirstClassProperties, EmailMessageSchema.From, EmailMessageSchema.ToRecipients));
return items.Select(item =>
{
return new MailItem()
{
From = address,
Recipients = ((Microsoft.Exchange.WebServices.Data.EmailAddressCollection)item.Item[EmailMessageSchema.ToRecipients]).Select(recipient => recipient.Address).ToArray(),
Subject = item.Item.Subject,
Body = item.Item.Body.ToString(),
};
}).ToArray();
}
catch (Exception ex)
{
throw ex;
}
}
I need a solution for fetching the body content for appointments from exchange server.
Assuming you are already connecting to the Exchange service successfully and only trying to retrieve appointments body part please try this.
Try Adding EmailMessageSchema.Body to your property set.
service.BindToItems(findResults2.Select(item2 => item2.Id), new PropertySet(BasePropertySet.FirstClassProperties, EmailMessageSchema.From, EmailMessageSchema.Body, EmailMessageSchema.ToRecipients));
Here is my code for obtaining some calendar items (appointments) from EWS. But this throws an exception all the time.
The Exception:-
The property can not be used with this type of restriction.
private void GetChangedAppointmentInformation(Appointment appointment)
{
try
{
// Save appointment details into local variables
id = appointment.Id.ToString();
body = appointment.Body;
duration = appointment.Duration;
end = appointment.End;
bookingKey = appointment.Subject;
subject = appointment.Subject;
location = appointment.Location;
ItemView view = new ItemView(1000);
// Create a search filter that filters email based on the existence of the extended property.
SearchFilter eq = new SearchFilter.IsEqualTo(AppointmentSchema.ICalUid, appointment.ICalUid);
// Search the Calendar with the defined view and search filter. This results in a FindItem operation call to EWS.
FindItemsResults<Item> findResults = service.FindItems(WellKnownFolderName.Calendar, eq, view);
}
catch (Exception ex)
{
Console.WriteLine("Error: " + ex.Message);
}
}
Can you please advise me on this? I tried MSDN and several other online resources, I'm still trying to figure that out.
The error is telling you that the strongly typed property you're trying to use can't be used in a restriction. The best workaround for this is to use the equivalent Extended Property instead eg to search based on a existing appointment something like
Appointment newAppointment = new Appointment(service);
newAppointment.Subject = "Test Subject";
newAppointment.Start = new DateTime(2012, 03, 27, 17, 00, 0);
newAppointment.StartTimeZone = TimeZoneInfo.Local;
newAppointment.EndTimeZone = TimeZoneInfo.Local;
newAppointment.End = newAppointment.Start.AddMinutes(30);
newAppointment.Save();
newAppointment.Body = new MessageBody(Microsoft.Exchange.WebServices.Data.BodyType.Text, "test");
newAppointment.RequiredAttendees.Add("attendee#domain.com");
newAppointment.Update(ConflictResolutionMode.AlwaysOverwrite ,SendInvitationsOrCancellationsMode.SendOnlyToAll);
ExtendedPropertyDefinition CleanGlobalObjectId = new ExtendedPropertyDefinition(DefaultExtendedPropertySet.Meeting, 0x23, MapiPropertyType.Binary);
PropertySet psPropSet = new PropertySet(BasePropertySet.FirstClassProperties);
psPropSet.Add(CleanGlobalObjectId);
newAppointment.Load(psPropSet);
object CalIdVal = null;
newAppointment.TryGetProperty(CleanGlobalObjectId, out CalIdVal);
Folder AtndCalendar = Folder.Bind(service, new FolderId(WellKnownFolderName.Calendar,"attendee#domain.com"));
SearchFilter sfSearchFilter = new SearchFilter.IsEqualTo(CleanGlobalObjectId, Convert.ToBase64String((Byte[])CalIdVal));
ItemView ivItemView = new ItemView(1);
FindItemsResults<Item> fiResults = AtndCalendar.FindItems(sfSearchFilter, ivItemView);
if (fiResults.Items.Count > 0) {
//do whatever
}
Should work okay
Cheers

Hello I am using the following code to get the custom header from EWS.
But unfortunately it's not returning the header. I looked into the outlook for the headers using Mapi tool, where I can see the headers.
Any suggestions please.
service = ExchangeServiceHelpers.GetBinding();
// Bind the Inbox folder to the service object
var inbox = Folder.Bind(service, WellKnownFolderName.Inbox);
var searchFilter = ExchangeServiceHelpers.PopulateSearchFilters();
var view = new ItemView(int.MaxValue); // Search operation should return maximum number of elements.
// Defines a property set that contains the schematized Internet message headers.
var headerProperty = new ExtendedPropertyDefinition(
DefaultExtendedPropertySet.InternetHeaders,
"x-worksitefolderemailid",
MapiPropertyType.String);
var columns = new PropertySet(BasePropertySet.IdOnly, EmailMessageSchema.InternetMessageId, headerProperty);
view.PropertySet = columns;
// Fire the query for the unread items
var findResults = inbox.FindItems(searchFilter, view);
// Loop through the search results.
foreach (EmailMessage message in findResults)
{
try
{
message.Load(
new PropertySet(new PropertyDefinitionBase[] { ItemSchema.MimeContent, ItemSchema.Subject}));
string mailAddress = GetFolderId(message, headerProperty); // Get internet header
if (string.IsNullOrEmpty(mailAddress))
{
Logger.Info(
string.Format("Email '{0}' doesn't have folder id address. Marking as Read Item.",
message.Subject));
ExchangeServiceHelpers.MarkMessageAsRead(service, message.Id); // Marking the email item as Read prevents the item to be returned in further search results.
continue;
}
}
catch (Exception e)
{
Logger.Error(e);
}
}
private static string GetFolderId(EmailMessage message, ExtendedPropertyDefinition headerProperty)
{
try
{
if (message.ExtendedProperties == null || message.ExtendedProperties.Count == 0)
{
Logger.Info(
string.Format("Email '{0}' doesn't have any extended properties. Marking as Read Item.",
message.Subject));
return string.Empty;
}
//message.InternetMessageHeaders
foreach (ExtendedProperty property in message.ExtendedProperties)
{
if (property.PropertyDefinition == headerProperty)
{
return property.Value.ToString();
}
}
}
catch (Exception ex)
{
Logger.Error(ex);
}
return string.Empty;
}
Naresh,
The inbox.FindItems() call won't return the internet headers. You'll need to update message.Load() to use a property set that includes headerProperty.
With regards,
