I have some users that when they update their inbox via an outlook 2010 client, the changes they made take a long time to update on Outlook Web Access (OWA). When testing, via another outlook 2010 client I see the changes to the inbox are updated real time inside of OWA.
The environment is - 2 CAS/HT servers in a NLB array. 2 MBX servers in a DAG. All 2008 R2, and exchange 2010.
Having a tough time isolating this issue, while I feel that its client side, its happening to more than 3 users at current (happened sporadically to more users last week).
I am unable to find errors to correlate to this issue. Any help is appreciated.
