We've been recently spent a lot of time in Outlook for Mac 2011 and our experience has NOT been good.
- We can't move entire folders from one mail server to another
- We can't select multiple folders using either the Shift or Command keys
- It's frustrating to perform a simple task like rename a folder because any progress (sending, receiving, updating) that takes place in Outlook during the renaming process will kick you out of the folder and you'll be forced to try again.
- Outlook is just plain slow compared to Apple Mail.
It's little stuff but it amounts to a HUGE pain when trying to migrate an Outlook user from one IMAP mail server to another -- especially a user with a lot of folders, and subfolders.
Here's a workflow we've developed, that is far from ideal but seems to get the job done most consistently, efficiently and with the least amount of errors.
- Confirm the following in Outlook > Preferences > Accounts > Source IMAP Account > Advanced > Server
- CHECK: Always download complete messages bodies
- UNCHECK: In Inbox only
One downside to this process is that all migrated mail will arrive as "unread". You plan to read them all again at some point, right? That's why you're saving them. :) In Apple Mail you can select a folder, right-click and choose to Mark All Messages as Read.
At this point you are done. You can either remain in Mail and ditch Outlook (recommended) or go back to Outlook and setup your new IMAP account. All your old messages and folder structures will be available. Hooray!
