We have SBS 2011 running in our office. When any of the users try to use OWA to access their email remotely they use IE and go to https://mail.companyname.com/owa
. This presents the normal login screen and they are prompted for username and password as usual.
On clicking Sign-in they get the following error in the browser;
405 - HTTP verb used to access this page is not allowed.
The page you are looking for cannot be displayed because an invalid method (HTTP verb) was used to attempt access.
As far as we can see there hasn't been any recent update applied and the server has not been reset within the last few days. All the usual things like repair my network, iisreset etc are not helping. Really at a loss here.
