The Exchange 2003 was upgraded to Exchange 2010 and everyone was on Outlook 2007 and had no problem connecting Inbox and Public folders, after the the migration to Exchange 2010.
But when the client computers were upgraded to Outlook 2007 to 2010, some users had no problem connecting but handful of users cannot connect to the same public folders.
They can connect to the inbox, no problem.. just the public folders.
It says outlook could not log on to the Exchange, when public folder is clicked on. Any ideas?
