Exchange 2010 OWA error for random users
Posted on 2012-09-02
Admin users with Full Access permissions over staff mailboxes open additional mailboxes within OWA and receive the following error when clicking links such as Mailbox Name (to get to Options), New E-mail, etc:
Your request couldn't be completed.
This may have occurred for security reasons or because your session timed out.
Environment consists of 5x Server 2008 Servers running Exchange 2010 v14.1 (Build 218.15) in a DAG configuration (2x HUB/CAS, 2x Mailbox, 1x DR).
Admin guys access additional mailboxes via OWA to set Out of Office for staff members.
As I said it is only happening for a few client mailboxes.
Any help would be much appreciated.
