I work with Exchange but i do quite a few other things and i don't get to wear my exchange hat often so I forget some of that knowledge.
Situation: 1 domain with multiple sites. Currently 2 Exchange 2010 servers at two main sites.
Site 1 users mailboxes are located on Site 1 Exchange 2010 server.
Site 2 users mailboxes are located on Site 2 Exchange 2010 server.
Users want to be able to go from Site 1 to Site 2 and have their mailbox connect to the site local exchange serve due to not a very good link between the sites. Users also sometimes have a pretty large mailbox (1GB) which often chokes on trying to download to client.
OWA is enabled, and they technically could use this.
Just looking to see if it is doable or if they should just stick with OWA
