exception when retriving user name

[Jason Wang]

I get exception while retrieving user name from email account profile in 2
computers, one is using pop3 account with OUtlook 2007, the other Exchange
account with Outlook 2003 (connected to Exchange server OK). No problems in a
few other PCs and XP/Vista VMs. Someone please tell me why and how to avoid
that.

Environment: VS2005, VSTO SE, Outlook 2003/2007, pop3/Exchange

The code (inside ThisAddIn_Startup method):

if (Application.Session.CurrentUser.Name == "Unknown")

The exception:

System.Runtime.InteropServices.COMException (0x9AC40201): The messaging
interface has returned an unknown error. If the problem persists, restart
Outlook.

It is possible that Outlook is not yet fully initialized when you process
the event.
Try to wait for the Application.MAPILogonComplete event.
