We run Exchange 2010 SP1 and we have seen at least 2 IE 9 users be able to logon to OWA but cannot click on anything within the mail interface. I have verified with one user that clicking on 'compatibility mode' icon in IE9 allows normal operation.
Strangely enough my account will work fine on the same browser/machine/profile.
Question is I guess is why does it happen? This is the latest browser and Exchange version with SP1. The only thing I see out of date on the OS at a quick glance is I have not yet applied 2008R2 SP1 to the Exchange Servers.
Any fixes or a way to automate the 'compatibility mode' switch over?
