Outlook Interop: how to iterate all the calendars? - c#

I want to get all events from all calendars, how do i iterate thru all calendar folders and then all events for each calendar?

If I had to guess, though I'm just getting in to Outlook myself, I would suggest the following:
Outlook.Application app = new Outlook.Application();
Outlook.NameSpace ns = app.GetNamespace("MAPI");
Outlook.MAPIFolder folder = ns.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderCalendar);
Then something along the lines of
foreach (outlook.MAPIFolder subFolder in folder.Folders)
{
// do something with subFolder
}
And you could probably create something recursive to exhaust all possibilities of the MAPIFolder.Folders property.
EDIT Ultimately, try stepping through in the debugger one you've gotten the default folder and see what you're left with. My guess is this will have the information you need.

Move multiple mails to a folder in a different store

I'm using Outlook Redemption library (http://www.dimastr.com/redemption/home.htm) for my Outlook AddIn. I want to move multiple mails from an exchange account to a PST store.
onlineAccountFolder.Items.MoveMultiple(onlineEntryIds, targetFolderInPstStore);
The source folder mails were cut from the Exchange account, but not pasted in the target folder. They are gone.
I tried the same operation on an Exchange account folder in the same store and the move operation was successful. The items were moved to the target folder.
There's no overload of the 'MoveMultiple' method where I can define a StoreID.
I had no problem with the following script executed from OutlookSpy (I am its author - click “Script Editor” button on the OutlookSpy toolbar, paste the script, click Run.
The script moves the messages selected in Outlook to a folder returned by the PickFolder method. Works as expected with both PST and Exchange target folders.
set Session = CreateObject("Redemption.RDOSession")
Session.MAPIOBJECT = Application.Session.MAPIOBJECT
dim messages()
set sel = Application.ActiveExplorer.Selection
redim messages(sel.Count-1)
for i = 1 to sel.Count
messages(i-1) = sel.Item(i).EntryID
next
set targetFolder = Session.PickFolder
set sourceFolder = Session.GetFolderFromID(Application.ActiveExplorer.CurrentFolder.EntryID)
sourceFolder.Items.MoveMultiple messages, targetFolder
Use the Move method of the RDOMail class to move items between stores in Outlook.

OpenSharedItem for opening .MSG files showing Error in Outlook C#

I am using the following code to open the signed/unsigned
Outlook messages and I display the content in WebBrowser control.
Microsoft.Office.Interop.Outlook.Application app = new Microsoft.Office.Interop.Outlook.Application();
var item = app.Session.OpenSharedItem(msgfile) as Microsoft.Office.Interop.Outlook.MailItem;
string message = item.HTMLBody;
app.Session.Logoff();
It is working fine for the first time the file is opening, but after
closing the Outlook file trying to reopen the file it showing the
following error:
"Cannot open file: C:\tion.msg. The file may not exist, you may not
have permission to open it, or it may be open in another program.
Right-click the folder that contains the file, and then click
Properties to check your permissions for the folder."
After some time later it is opening fine. For this strange behavior
what could be the reason and how to rectify the the error message?
Outlook manages its own cache of items when you are opening and closing messages. Your best bet would be to use a randomly generated filename (i.e. Path.GetRandomFilename) when opening via OpenSharedItem so that you don't get issues. I would also use a temporary path instead of root c:\ (i.e. Path.GetTempPath).
You can try and free the MailItem reference (i.e. setting it to null), but there is no guarantee when Outlook will release the item from its cache.
Would any combination of the Quit[1], Close[2] or ReleaseComObject[3] methods work for you? My code worked better but not perfect after I used them.[4]
using Outlook = Microsoft.Office.Interop.Outlook;
.
.
.
var app = new Outlook.Application();
var item = app.Session.OpenSharedItem(msgfile) as Outlook.MailItem;
//Do stuff with the mail.
item.Close(OlInspectorClose.olDiscard);
app.Quit();
Marshal.ReleaseComObject(item);
Another solution, according to Microsoft - Help and Support[5], is to delay the opening of the file. However, it doesn't sound like a good solution to me since, like #SliverNinja also said, you'll never know when Outlook releases its lock of the file.

For example, if I had opened Outlook for som regular work, the Quit-method would close that window as well.

Hello you have two options .
set the Read-only attribute to the msg file
or
disable the following permissions for the users or usergroups to the parent folder:
Write Attributes
Write Extended Attributes
the msg file can now open multiple times but is write protect
I had this problem, in my case it was the space in the file name
import win32com.client
import os
path = 'C:/testes/mail'
files = [f for f in os.listdir(path) if '.msg' in f]
for file in files:
outlook = win32com.client.Dispatch("Outlook.Application").GetNamespace("MAPI")
msg = outlook.OpenSharedItem(os.path.join(path, file))
att=msg.Attachments
for i in att:
i.SaveAsFile(os.path.join('C:/testes/email_download', i.FileName))
I don't know if in your case the OpenSharedItem method can help ...
Firstly, try to release the message as soon as you are done with it using Marshal.ReleaseComObject(). This may or may not help since Outlook likes to cache its last opened item.
Secondly, you are logging off from Outlook while it might still be running and visible to the user - Outlook is a singleton, so you will end up with the existing instance if it was already running. Either don't call Logoff at all, or check that there are no open inspectors and explorers (Application.Explorers.Count == 0 && Application.Inspectors.Count == 0).
Thirdly, reading HTMLBody alone won't work properly if there are embedded images - they are stored as regular attachments. You can save the message as an MHTML file (which most browsers would be happy to show) using MailItem.SaveAs(..., olMHTML).
You can also use Redemption (I am its author) for that - call RDOSession.GetMessageFromMsgFile.
If you need to release the message immediately after you are done, call Marshal.ReleaseComObject()
In case of Redemption, you can also cast RDOMail object to the IDisposable interface and call IDisposable.Dispose(). In addition to the MHTML format, Redemption can also save in the HTML format with image attachments converted into embedded images- use RDOMail.SaveAs(..., olHTMLEmbeddedImages) (olHTMLEmbeddedImages == 1033).

Open Specific MailItem in Outlook from C#

I want to open a specific email in Outlook from my C# winforms application.
At the moment I have got the following code:
//...Get Folder & Entry ID for last Email in Sent Box
Outlook.Application myApp = new Outlook.ApplicationClass();
Outlook.NameSpace mapiNameSpace = myApp.GetNamespace("MAPI");
Outlook.MAPIFolder mySentBox = mapiNameSpace.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderSentMail);
Outlook.MailItem myMail = ((Outlook.MailItem)mySentBox.Items[1]);
string guid = myMail.EntryID;
string folderEntryID = mySentBox.EntryID;
string folderStoreID = mySentBox.StoreID;
string mailAddressee = myMail.To;
MessageBox.Show(mailAddressee);
//...Attempt to Open that Email at a later date
Outlook.MAPIFolder getFolder = (Outlook.MAPIFolder)mapiNameSpace.GetFolderFromID(folderEntryID, folderStoreID);
Outlook.MailItem getItem = (Outlook.MailItem)getFolder.Items.Find("[EntryID] = " + guid);
getItem.Display();
The first an second parts of the code will be run at different times, although they are in the same Method for testing at the moment.
The first part obtains the relevant IDs for the mst recently sent email from Outlook. This part seems to work fine as evidence my the Messagebox I've built in.
The second part however is not working and I'm struggling to find the right code to access and open that specific mailItem having obtained its ID and folder location in the first part.
Anyone able to complete this little project for me please.
Done it at last by replacing the following lines of code . . .
Outlook.MAPIFolder getFolder = (Outlook.MAPIFolder)mapiNameSpace.GetFolderFromID(folderEntryID, folderStoreID);
Outlook.MailItem getItem = (Outlook.MailItem)getFolder.Items.Find("[EntryID] = " + guid);
with this . . .
Outlook.MailItem getItem = (Outlook.MailItem)mapiNameSpace.GetItemFromID(guid, folderStoreID);
You can not use EntryId with the _Items.Find method. The MSDN reference is here.
There is also a remark which could be interesting for your project:
"The Entry ID changes when an item is moved into another store, for
example, from your Inbox to a Microsoft Exchange Server public folder,
or from one Personal Folders (.pst) file to another .pst file.
Solutions should not depend on the EntryID property to be unique
unless items will not be moved."
MailItem.EntryID Property (Outlook).

Problem with reading *.msg outlook file using Microsoft.Office.Interop.Outlook

I'm writing piece of code which will handle extraction of information from email stored in *msg Outlook file. The idea how to do it I took from C# Outlook interop and OpenSharedItem for opening MSG files. But when calling method OpenSharedItem a get such error System.AccessViolationException. Anyone know what's the problem?
Here is code causing error
Outlook._Application app = new Outlook.Application();
Outlook.NameSpace NS = app.GetNamespace("MAPI");
Outlook.MAPIFolder inboxFld = NS.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderInbox);
Outlook.MailItem fld = (Outlook.MailItem) app.Session.OpenSharedItem("E://Projects//C#//message1.msg");
Ok. In case anybody will face the same problem finally I've got an answer. First of all should be
Outlook.MailItem fld = (Outlook.MailItem) app.Session.OpenSharedItem("E:\\Projects\\C#\\message1.msg");
difference is in the slashes.
Then all you need to make it work is Outlook 2007 or newer. And that's it :]

Using Outlook API to get to a specific folder

I'm trying to write some C# code to get to a specific folder in an Outlook mailbox. I have the following code:
Outlook.Application oApp = new Outlook.Application();
Outlook.NameSpace oNS = oApp.GetNamespace("mapi");
Outlook.Recipient oRecip = oNS.CreateRecipient("AccountNameHere");
oRecip.Resolve();
if (oRecip.Resolved)
{
oInbox = oNS.GetSharedDefaultFolder(oRecip, Outlook.OlDefaultFolders.olFolderInbox);
oInboxMsgs = oInbox.Items;
ItemCount = oInboxMsgs.Count;
Console.Writeline("There are {0] items.", ItemCount.ToString())
}
This will get me to to the "Inbox" folder. I'm trying to get to a folder at the same level as the Inbox folder. I believe I need to use GetFolderFromID instead of GetSharedDefaultFolder, but I don't understand how to use it. Is there a way to iterate through all the top level folders? How might I determine the EntryID and StoreID of the folder?
Thanks!
You can use the Folders collection member of the Outlook.NameSpace object. That way you can iterate through the collection and find your folder by it's name. In case you still want to use GetFolderFromID, you can use OutlookSpy tool to get the EntryID and StoreID values.
