I'm in the middle of upgrading from Exchange 2007 on-premises to 2013 on-premises. Some users are still on Ex2007 and some have been moved to Ex2013. I have a large Public Folders database that still resides on 2007.
The users who have been migrated to Ex2013 cannot view the public folders in Outlook. Outlook will show the Public Folder tree. However, when we click on a folder to view it, then Outlook just shows a progress bar and never shows any of the contents inside the Public Folder. This happens on all Public Folders in the tree.
Any ideas? I was under the impression this would work.
I tried enabling Outlook logging. However, I didn't get any good information from it.
Could it have anything to do with how large my Public Folder database is? We have over 20,000 folders in our database.
