Hi Everyone, We just did our updates to Exchange 2010 (RU5) and now some of my users myself included using Outlook 2007 in cache mode that had left Oulook open during the updates recieved a windows login prompt for the Public Folder Server we have associated with our mailbox. I closed and restared outlook and it went away. My question is, is this something I have to educate my users on that they will have to expect from now on. This is the first time its happened v/r john
