I have a client that is interested in moving to Exchange Online/Office 365 from a POP3 provider. When it's an all PC environment these migrations are a piece of a cake - export/import the PSTs through Outlook and you're done. The Mac side of things has me a little stumped.
Currently their email environment is a bit of a mess. They use a POP3 provider with a variety of setups in their office...
- PCs with Outlook 2010 using POP3. Not a concern, simple PST import/export.
- Macs with Outlook 2011 using POP3. Import/export with .olm files works, but it's drawn out and requires manual adjusting because it creates a second-tier "Inbox". Is there anyway to import .olm files to the root of the Inbox in Outlook 2011? When I test the import process it imports like Inbox > Inbox > Sub folder 1 > Sub folder 2 etc. I need it to import without the two-layered inbox. I can manually move all of the sub folders into the top level Inbox but that will be very time consuming as many users have hundreds of nested folders.
- Macs using Apple Mail and Postbox (some POP3, some IMAP). I'm most concerned with these users. I'm not sure how to proceed with these mailboxes and the export procedures are useless in both applications as far as I can tell. The IMAP users should have all of the data still on the POP3 server so I'm hoping I can configure those accounts in Outlook on a PC and go the export/import PST route. The POP3 users though, I'm really not sure how to approach.
Any tips or recommendations?
