I have recently taken over as the admin for a company running Exchange 2010 on a SBS 2011. They are having a problem with the MailTips working on all desktops. Only one current user is able to receive MailTips notifications and the rest say MailTips could not be retrived. there is the folder shares GroupMatrics and ExchangeOAB. GroupMatrics files are updated daily and ExchangeOAB has not updated in the past few months. on the work station that is currently not having any issues you can access there OWA fine. With all others the webpage is unreachable. Any suggestions or ideas what is wrong?
