I am analyzing a users Exchange mailbox with calls to the ExchangeService. This tool needs to run on the client environment periodically and by ommiting the credentials to the service I am connecting to the Exchange Service as the logged in Windows User. I can succesfully loop thrue the folders and items.
Now I want tot retrieve the information about the mailbox being used. Username and (main) E-mail should suffice. But I cannot find anything about how to retrieve this information. Every example provides credentails for the user, or auto-discovering the Exchange service from the e-mail adres. I do not want the user to configure anything :-).
Any suggestions?
ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2007_SP1);
service.Url = new Uri("https://FQDN/EWS/Exchange.asmx");
???
FindItemsResults<Item> findResults = service.FindItems(WellKnownFolderName.SentItems, new ItemView(100)); // this works
I've tried using service.ResolveName, but that can give multiple answers, even using Environment.UserName
The easiest method to do this is to use ConvertId operation and use unresolvable address (blah#blah.com always works for me) in the Mailbox element. Exchange should convert this to the actual Mailbox in the response. eg
Folder chk = Folder.Bind(service, WellKnownFolderName.Inbox);
AlternateId aiItem = new AlternateId();
aiItem.Mailbox = "Blah#Blah.com";
aiItem.UniqueId = chk.Id.UniqueId;
aiItem.Format = IdFormat.EwsId;
String CasServer = service.Url.Host.ToString();
AlternateIdBase caid = service.ConvertId(aiItem, IdFormat.HexEntryId);
Console.WriteLine(((AlternateId)caid).Mailbox);
Cheers

I've using a custom GetMailTips SOAP call (since the EWS for Core 2.0 doesn't support it) to get Out of Office info for a batch of email addresses.
How can I get the display names of the users that I am passing in the email address for?
I can call ResolveName of the managed API and that works but it has to be done one at a time and that is slow. I would like to ideally get this info out when I make my GetMailTips request and failing that make a call with all the email addresses to get the Display Names all at once. I read there is meant to be a ResolveNames method but that's not in the API either.
Any help appreciated
Autodiscover can return that for multiple users eg
AutodiscoverService adService = new AutodiscoverService(ExchangeVersion.Exchange2013_SP1);
adService.Credentials = new NetworkCredential("user#d.com", "pass");
adService.RedirectionUrlValidationCallback = adAutoDiscoCallBack;
List<String> Users = new List<string>();
Users.Add("user1#domain.com");
Users.Add("user2#domain.com");
GetUserSettingsResponseCollection usrSettings = adService.GetUsersSettings(Users, UserSettingName.UserDisplayName);
foreach(GetUserSettingsResponse usr in usrSettings)
{
Console.WriteLine(usr.Settings[UserSettingName.UserDisplayName]);
}
Another way would be to create a Message and add the email address as recipients then save it to the drafts folders and the address should get resolved against the GAL.
I have a problem: I need to connect from a remote server to Active Directory, but the code has to be using the LdapConnection class. I need this because that way I can only test change notifiers when some event happen (such as user is deactivated or he changed group, data etc). OS on the remote server is Windows Server 2012.
I managed to do this from local using DirectoryServices with the following code:
String ldapPath = "LDAP://XRMSERVER02.a24xrmdomain.info";
directoryEntry = new DirectoryEntry(ldapPath, #"A24XRMDOMAIN\username", "pass");
//// Search AD to see if the user already exists.
DirectorySearcher search = new DirectorySearcher(directoryEntry);
search.Filter = "(&(objectClass=user))";
SearchResult result = search.FindOne();
This is okay and connection works but now I need to connect using the LdapConnection class.
I tried something like this on many ways but none of that helped me:
LdapConnection connection = new LdapConnection(XRMSERVER02.a24xrmdomain.info);
var credentials = new NetworkCredential(#"A24XRMDOMAIN\username", "pass");
connection.Credential = credentials;
connection.Bind();
It says that credentials are invalid but that is not true.
Explanations:
XRMSERVER02 - Domain controller
a24xrmdomain.info - Domain
A24XRMDOMAIN - Domain used for logging
Thanks for your help.
Even though I solved my problem I want to share with other developers what I achieved so far. Problem that I encountered was that I had remote server with OS Windows server 2012 and Active directory on it. I needed to connect on him via my local machine(Windows 10).
As I stated in my question it is possible to do that via DirectoryServices with the following code:
String ldapPath = "LDAP://(DomainController).a24xrmdomain.info";
directoryEntry = new DirectoryEntry(ldapPath, #"DOMAIN\username","pass");
//// Test search on AD to see if connection works.
DirectorySearcher search = new DirectorySearcher(directoryEntry);
search.Filter = "(&(objectClass=user))";
SearchResult result = search.FindOne();
This is one of the solutions, but since my task was to get notification and to identify when ever some object has changed in Active Directory, I needed connection to Active Directory on Remote server via LDAP class. Code for getting notifiers is taken from:
- Registering change notification with Active Directory using C#
I succeeded to connect with LDAP class via next code:
String ldapPath2 = "(DomainController).a24xrmdomain.info";
LdapConnection connection = new LdapConnection(ldapPath2);
var credentials = new NetworkCredential(#"username", "pass");
connection.Credential = credentials;
connection.Bind();
Want to mention that no IP address of remote server is needed, just Domain Controller that is used on him, and that Domain used for logging is unnecessary.
Happy coding
Try using NetworkCredential constructor with 3 parameters: username, password and domain. Specify domain separately from user name
I'm creating an app that needs to get the permissions for each MailBox, and I can't seem to get it to work. I've noticed in the VS Object Browser that the Permissions property is on the Folder class.
So I'm guessing I need to get the MailBox object and then get the root/default folder so I can get the Permissions.
This is what I've done so far, but when it calls Folder rootfolder = Folder.Bind(service, sharedMailboxRootFolderId); I get the following exception:
"The Client Access Server version does not match the accessed
resource's Mailbox Server version."
ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2007_SP1);
string exchangeServerWebServicesUrl = "https://example.com/EWS/Exchange.asmx";
service.Url = new Uri(exchangeServerWebServicesUrl);
string username = "*********************";
string password = "*********************";
service.UseDefaultCredentials = false;
service.Credentials = new WebCredentials(username, password);
Mailbox sharedMailbox = new Mailbox("shared#example.com");
FolderId sharedMailboxRootFolderId = new FolderId(WellKnownFolderName.Root, sharedMailbox);
Folder rootfolder = Folder.Bind(service, sharedMailboxRootFolderId);
var permissions = rootfolder.Permissions;
I've tried passing in different ExchangeVersion enum values, but they don't work either. But passing ExchangeVersion.Exchange2007_SP1 does work when I try and get the Public Folders root folder.
Folder rootfolder = Folder.Bind(service, WellKnownFolderName.PublicFoldersRoot);
So the question is how can I get a MailBoxes permissions using EWS?
I've just found the Find out which users have Full Access on a mailbox post that says
You can't using EWS (or any of the Exchange Mailbox API's) you can
only access the Folder level DACL's what you need to read is the
Mailbox DACL which can only be either accessed via the Exchange
Management Shell (Get-MailboxPermissions) or via reading the
msexchmailboxsecuritydescriptor from Active Directory.
So it looks like it's not possible to get the MailBox permissions using EWS.
Shame.
This Microsoft page indicates that by setting the UseDefaultCredentials property to true, no login name and password are required to communicate with the Exchange server. However, that is not my experience.
My code creates an instance of ExchangeService called service:
ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2010);
If I manually set the credentials as follows, everything works just fine:
service.Credentials = new WebCredentials("my#email.address", "my password");
However, if I remove that line and replace it with the following, my code doesn't work:
service.UseDefaultCredentials = true;
I have searched and searched for solutions but I'm not finding anything concrete. If someone here could please help me I would be very grateful.
EDIT:
I tried to use my own credentials instead of the Default Credentials.
string smtpaddress = "somesharedsmtp#domain.com";
es.Url = new Uri("https://outlook.office365.com/EWS/Exchange.asmx");
es.Credentials = new WebCredentials("myemail", "mypassword");
es.AutodiscoverUrl(smtpaddress, RedirectionCallback);
FolderId SharedMailbox = new FolderId(WellKnownFolderName.Inbox, "somesharedsmtp#domain.com");
Folder sharedInbox = Folder.Bind(es, SharedMailbox);
At this point I can check sharedInbox containing the details of the Inbox. I can see the unread email count and others.
But when I access
ItemView itemView = new ItemView(100);
FindItemsResults<Item> findResults1 = es.FindItems(pqInbox.Id, itemView);
I get exception "SMTP address has no mailbox associated with it"
my experience in that case is, that if you set service.UseDefaultCredentials = true your Login of your pc will be taken. Which works perfect if your in the same ActiveDirectory structure as the exchangeserver is. If your trying to connect to the exchange server from outside of the ADS you will have to set the credentials manually.
I'm using the defaultcredentials for my tools when I'm at work. If I connect from at home I have to set the credentials.
Hope that helps you...
From MSDN documentation, UseDefaultCredentials is ignored in Exchange Online. You must specify credentials for Exchange Online.

I have UI where I have the user enter the Url where I can find the Exchange Web Service(EWS). My application uses EWS to get Free/Busy information but my configuration tool just needs to set it for the user.
For now I am just asking for the host name and building up the Url from there. For example they enter example.org as the host and I build https://example.org/EWS/Exchange.asmx from that.
I would like to add a test button to ensure the host they entered is reachable by the machine they are configuring. But I'm not sure how simple or complex I need to be to test the service.
Is there any noop or bind I can do to make sure I can establish communication with EWS?
Something like:
var serviceUri = new Uri(_textBoxEwsUrl.Text));
var exchangeService = new ExchangeService();
exchangeService.Url = serviceUri;
// what can I call here to test that I can talk to the exchangeService?
exchangeService.????
Bind to the inbox folder of the users mail address. Of course, you would need his credentials to this.
Any kind of operation that results in communication with server can be used as test. Simple binding to any folder or item will throw ServiceRequestException or some different type of exception if your url or credentials are incorrect.
Sample code:
try
{
var inbox = Folder.Bind(service, WellKnownFolderName.Inbox);
}
catch(ServiceRequestException e)
{
//handle exception in some way
}
