Hi - I have roughly 500 users in my organization on Exchange 2010. We are going to Google Apps (K12 environment) and I would like to forward incoming all mail from the Exchange server to our new Google Domain. My user names are all the same, (e.g. email@example.com = firstname.lastname@example.org).
Rather than hope my users could write their own rule to forward their mail from the exchange address to the google address, and rather than access each of 500 mailboxes one at a time to forward the email, can somebody help me with a script or the command line(s) to use the Exchange Shell to add a forwarding rule to all of my users mailboxes? If I could limit it by OU, then I could test/troubleshoot and then phase in the mass-forwarding, but that is not a requirement if it is not an option.
I am thinking that just adding the forward to the google domain and also deliver the message to the original Exchange mailbox would be best, rather than just shoving them all to the Google Account...
Any help the experts can provide is appreciated!
