Running Exchange 2007 SP2 on 2003 R2 Enterprise SP2
Users go to our internal homepage and click on webmail link to access OWA. Page that pops up says IE cannot display this page. If user hits refresh enough times it will eventually come up. This started Tuesday morning but no changes were made to Exchange or any pc's Monday night. There are also no errors on Exchange box.
Also, sometimes when users try to reply to an email, the email box pops up blank.
It is happening with both Vista and win7, both 32-bit, but IE version ranges from 8 to 10.
