I have an odd error I have not seen before and since my 2007 commands aren't fully tweaked I have to request some assitance.
We recently migrated from Exchange 2003 to Exchange 2007 and have fully decommissioned the old mail server. Unfortunately the new mail server, despite having reported taking over the public folder roles, is not displaying them to Outlook clients internally. Even after creating a brand new profile for a user with rights, Outlook 2007 clients receive the following error when attempting to expand the All Public Folders tree:
"Cannot expand the folder. The attempt to log on to Microsoft Exchange has failed."
Clicking on the All Public Folders folder generates the following error:
"Cannot display the folder. Microsoft Office Outlook cannot access the specified folder location. Could not open the item. Try again."
Attempting to right click and manage properties also fails.
Now here's the kicker. If we log in as the same user in OWA with public folders on, they can see, browse, post to the public folders, edit permissions etc just like normal. It's only when they are using Outlook 2003/2007 that they are unable to view them. This issue affects all clients via RDP, Outlook Anywhere, LAN etc - just not via Outlook Web Access!
Winning answer gets big points. There can be only one...
