We have exchange 2010 , CAS/MBX/HUB all on one server. All was working fine until 1st issue reported that owa is not working with webmail.company.com and it was fixed. but now OWA users are unable to open any attachment. error received is page cannot be displayed. when trying to open attachement it redirects to URL https:// webmail.company.com /attachement.ashx ...x.....x...x and after a while page cannot be displayed error comes.
Any suggestion please.
