Current setup: Outlook 365 Pro Plus client and Exchange server 2013 CU6 on-premise houses the mailboxes I am trying to find out what the folder view object is and how it is used, this error is only appearing for one user reporting freezing when he goes to edit calendar items. He has other glitchy behaviour as well which I am still trying to troubleshoot but so far the most obvious is the event error being recorded. I have increased the counts via the registry fix as suggested by many sites and blogs, but I still want to know what the Folder Object view is and why he is reaching the max in the first place.

Can anyone elaborate or know of a site that explains what a folder view is and how a user can reach the maximum?

From Outlook 2010 on you can put the shared mailboxes in online mode and it won't count towards the 500 folder total. share|improve this answer answered Apr 8 a
