No, No, NO!! No IMAP. Many people are saying IMAP, and, having gone through this personally, I will tell you ... No! Did I emphasize that enough?
The answer is Google Apps Sync for Outlook. It's far more native, far more reliable, and it supports the calendar and addressbook too. All of it goes into a PST file. https://tools.google.com/dlpage/gappssync Unless you find a tool that's specifically made for this purpose, migrating a domain of users from gmail to exchange, GASO is going to be your best tool. It has only one downside. You'll have to do each user individually. That's the only thing you could possibly gain by switching to some other tool. If you find an auto-migration tool that handles the whole domain, that would be something valuable which GASO can't do. Last year, we were planning a gmail to exchange migration. I asked the intern to backup everyone's mailboxes with outlook over IMAP, showed him how, and it was a disaster. Gmail and Outlook implementations of IMAP are like water and oil. Connections constantly resetting and just crapping out ... horrible server performance ... For 25 users, it took over a week. Interactive, busy time babysitting, rebooting etc. We're not talking "walk away for a week and it's done." And then because of Google's weird IMAP, you get all weird google-isms, like the "All Mail" folder, which contains a 2nd disk-hogging copy of every message that's already in some other folder. Google Apps Sync for Outlook doesn't have that issue. Deleted stuff appears in Trash, like normal. Drafts appear in Drafts, like normal. And so on. It's 1 million times better, and easily 5-10 times faster. And 100% reliable. Even with the biggest user's mailbox (15G) I just set GASO to download mail, leave it a few hours, and it's done. Be sure to click the sync icon in the corner. By default, it'll only download 1G of mail. Obviously, you want to change that to Unlimited. _______________________________________________ Tech mailing list [email protected] http://lopsa.org/cgi-bin/mailman/listinfo/tech This list provided by the League of Professional System Administrators http://lopsa.org/
