Exchange 2013 Public Folder Accessability Issues

Question

After migrating from Exchange 2010 to Exchange 2013 we are experiencing random issues accessing Public Folders.  Issues range from a hung server requests to on-screen errors like this one:
“Cannot expand the folder. Microsoft Exchange is not available. Either there are network problems or the Exchange server is down for maintenance”
We are using groups to manage permissions, verified that they are mail enabled, and have used the following PS command to re-propagate permissions:
./AddUsersToPFRecursive.ps1 -TopPublicFolder "%folder%" -User "%groupname" -Permissions %permissionlevel"
The odd thing is that if the user bounces between on of their Inbox folders then back to one of the Public folders or restarts Outlook it seems to resolve itself.
Ideas?

Hi Niko,
Firstly, apologies for the delayed update...
We are still experiencing random loss of access to Public Folders, I would think it would be so much easier if I could replicate the problem quickly and easily however that is not the case as I ran into this issue again this morning.
I am really at a loss for explanation, what I can offer is when we had migrated from Exchange 2000 to Exchange 2010 I had to export the PF out to a pst file prior to importing them on the new server installation.  While migrating from Exchange 2010
to Exchange 2013 we did follow the migration process.
