We have a hybrid set up between O365 and our Exchange 2013 server. Migrating users from on prem seems to work fine. After migration is complete, user can access their mailbox fine. But when they try to access public folders on the 2013 server, they get messages like “Cannot display the folder.”
The only fix is to have them create a new mail profile. While using their new profile, there is no problem with public folders. It also seems to work if we turn off cached mode. So to summarize:
If cached mode is left on, they are able to browse the public folder tree. But if they try to view the contents of any public folder, they get back :
If cached mode is turned off and Outlook restarted, they can see the contents of the public folders.
If we create a new mail profile for them with cached mode enabled, they can see the contents of the public folders.
Simply deleting the cache file does not fix this.
Any ideas what could be done to skip creating a new mail profile? I don't see why enabling cached mode on the existing profile breaks this.
