I have a Win7x64 workstation running IE9. When I log into OWA on that machine, I can read and send mail, but if I try to change any settings under Options, I get the following error:
Your changes were not saved because of a Microsoft Exchange error.
The error appears in a red bar where the "Changes saved" message would normally be.
Server is Exchange 2003, but as I don't manage the server, I don't have any further details.
My initial response was to treat it as a server issue, but this is the only PC having this problem. It works fine in Chrome on the same PC, but that's probably irrelevant, since it's using the light interface. I get the same error regardless of which user logs into OWA.
I've tried the obvious solutions like No Add-ons mode, full browser reset, but I'm still getting the error.
