We've got a single server setup of Microsoft Exhange 2010 SP1 + Update Rollup 2
There is also a legacy Exchange 2003 server with one user left on it. The Exchange 2003 server is genereting the OAB.
Suddenly for some reason, whenever I click "New E-mail" or reply to a mail in Outlook 2010, I now get a message saying MailTips could not be retrieved. I figure this has something to do with the EWS? Please help!
I would like to add that MailTips work from OWA and Outlook in online mode.
