Actually, this happens quite often with 3rd party Outlook plugins. We had a problem that we had to fix with the Linked In Addin, as well as some others. A lot of times, these addins make MAPI calls that cause us grief. The best idea would be to enable ZCO logging (just logging and http logging, not verbose). Then reproduce the problem in as small a window as you can, and send the ZCO log file. Hopefully, I can figure it out from there. |
