Global Exchange solution   

Hello,

We have a need for a more globalized Exchange solution.  Right now, we have 
a central front end and back end server in the US, and have associates all 
across the US connecting, and the other offices and associates worldwide.  
Anyone outside the US uses RPC over HTTP to connect, or OWA, and it is 
incredibly slow on both of them.  We need to provide these users in 
Europe/Asia the same performance we have here.

We have discussed placing an additional Exchange server in an office in 
Europe, and having the mailboxes of users outside the US routing here 
instead.  Then we could put an internet connector on that server and have a 
second MX record for their mail, which would also be a redundant path since 
the 2 servers would be interconnected across the ocean via a VPN tunnel.

We are currently looking for documentation with best practices and global 
Exchange solutions and can't find any.  Can anyone provide suggestions or 
documentation on how other organizations handle this challenge and what they 
do to resolve the issues?

Thanks!

Re: Global Exchange solution   

I would say make use of the NLB for your FE deployment to enhance 
performance and  increase your internet speed in front of your US-Based FE.

To have another Exchange in Europe and move Europe an Asia's Mailboxes to it 
will not improve anything if users still access OWA or RPC from your 
US-Based FE and it will go to retrieve the mail through the VPN that 
separates it from their BE, unless u create another OWA address for those 
users in Europe and ask them only to use it, in that case you will be having 
2 OWA addresses one in US and One in Europe for non-US associates.
