I have been tasked with migrating our corporate exchange server to office 365 :(.
The current configuration is as follows.
1: Web facing "outlook web access" on windows 2003 sp2 server 1: Exchange 2003 SP2 Mail Server on windows 2003 sp2 server
I have to perform a staged migration.
My concerns are as follows. I am following the documentation @ http://help.outlook.com/en-US/140/ff959224.aspx and all seems fine apart from outlook anywhere. Can I install outlook anywhere side by side with OWA or do I need a completely different server? Do I need to configure outlook anywhere will OWA suffice. Has anybody performed this migration before and if so can you highlight any pitfalls etc.
I have approx 110 - 120 GB of mailboxes to migrate.
Any help would be much appreciated.
