User exceeded the maximum of 500 objects of type "objtFolder
Posted on 2011-09-08
I have some users using Exchange 2007 and Outlook 2010 who get the following error:
Mail1: Mapi session "/o=<org name>/ou=First Administrative Group/cn=Recipients/cn=<first-name>.<last-name>" exceeded the maximum of 500 objects of type "objtFolder".
None have anything like 500 so the registry hack to increase the number allowed shouldn't be necessary, especially as only some users are having this problem. How can I find out what's causing Exhange to see hundreds of non-existant folders?
