I have recently planned to install an exchange server in branch office.
Craete new DAG and Install 2 DAG members and create new CAS Array for the databases of branch servers.
Please check this

Now what will happen if the branch office user access OWA from external network?
How this can be configured for branch users?

Example Main office is in US and and new branch office is in UK.
How UK users will access OWA from outside(internet)?

Hello,

Is your main office & branch office exchange servers in different AD sites?
If yes, then you may check this article for CAS proxying & redirection http://technet.microsoft.com/en-us/library/bb310763(v=exchg.141).aspx

If you using a single AD site then you may want to load balance the CAS url

I have only one AD domain. Created 2 AD sites for Site1 and Site2

Both has separate DAG and CAS Array configured. Both are internet facing.

How to configure Site 2 exchange server to connect site2 users connect directly site2 exchange server?

what i think is... when u create user on any of the exchange server it'll replicate to all of the  sites...

in this case ... u'll have multiple MX records..

it can be   for site 1   Mx1 and Mx2    for Site2 it could be Mx3 and Mx4 ... fir site 3 it could be Mx5 and Mx6

in the above scenario Site 1 is in USA, Site 2 is in UK, Site 3 is in Australia... that means
the owa will chose the best shortest path.

so it may go to the nearest path to get the mails...

am i right ?....

For example if I access mail.domain.com/owa
it resolves to ip of exchnage server is head office in US
If a user from branch office UK which has seperate DAG and CAS array try to open OWA do you think it will point to server in UK?

I am still not convinced of how the user will redirect to nearest server.

Any user who logs into a CAS server that doesn't serve the mailbox will get redirected to the correct CAS URL. In my environment you have to logon again to the correct CAS server, so your users should learn to go to the correct one to save time.

I have done that by redirecting silently to the remote owa without even login again
