Hi,
I have a solution where I'm using MAPI Store Accessor to monitor events such as copy item or new item for certain folders.
I initialize the component on startup, and close it again at shurt down:

private void adxOutlookEvents_Startup(object sender, EventArgs e)
{
// other code...
adxmapiStoreAccessor1.Initialize(false);
}
private void OfficeAddIn_AddinBeginShutdown(object sender, EventArgs e)
{
adxmapiStoreAccessor1.LogOff();
}


And on most computers this works perfectly. But on a few the user constantly recieve an error message when Outlook starts.
The problem occurs on both Windows XP and Server 2003, both with Outlook 2007. All in latest patch level.
Here is the text from the messagebox:

What could be the cause of this?

Additional information:
I found an old forum topic regarding the same problem, and there you suggested moving the initialization code to AddinModule_AddinStartupComplete. So I've tried this, but the same problem occured.

Maybe the Profiles or PSTs or something else of those users is password protected?

We have a demo version here which gives that error, and the demouser is not password protected beyon normal AD password, so I think it's doubtful that's the reason.

Hello Thomas,

Do you use an exchange account in the profile or POP3/IMAP?

I've changed the code to create a new MAPI session, to see if that changes anything.

adxmapiStoreAccessor1.Initialize(true);

On the computers that world already, it made no changes.
On the computers that didn't work, I now get a new error message:

More info: We've tested some more, and a user who has the problem on one computer, does not have it on another. So it may be related to the computer and not the user. We'll continue testing along this path...

After some testing we have discovered the following about the issue:

User 1 on PC 1 recieves the errormessage.
User 1 on PC 2 does not.
User 2 on PC 1 does not.
User 2 on PC 2 does not.

We have two users and two PC's that have this problem, and both follow the same pattern.
So it appears that the combination of a specific user on a specific PC gives the problem.
What in a users profile could prevent the MAPI logon?

We're thinking that the solution is to delete the profile from the PC, but the users have roaming profiles, so our customer is a bit reluctant to just delete (and recreate) the profile. A local prodile is okay, but a roaming profile may cause problems for other systems and solutions.
Can you offer any advise on the subject?

Regards
Thomas

Hello Thomas,

Nope. Hmmm... I haven't met such an issue before. Well, I think the cause of the issue lies in the settings of the user profile. Please try playing with its (a user profile) properties or try changing user properties on the exchange server side.
