This issue is only affecting a few specific users and it seems to be sporadic and spreading. The symptoms are:
-A random user first gets an error pop-up in Outlook while trying to move an email to a folder (within Outlook).
Error message: cannot display the folder. Your server administrator has limited the limited the number of items you can open simultaneously. Try closing messages you have opened...
-After that, Outlook crashes, throwing the error message:
Microsoft Outlook has stopped working. Restart the program.
-Outlook keeps crashing for this specific user until we disable the CRM 2013 for Outlook add-in.
This is what we have tried so far:
-Deleting local Outlook profile and re-creating it
-MS Office repair tool
-Deleting CRM for Outlook client and re-installing it
Does anyone know why this is happening, what is causing it and how we can fix it or at least troubleshoot?
