Here's the facts before my question:
>I have a client using Thunderbird to manage their emails
>There are 2 Users, on 2 separate computers
>Both have their email setup as IMAP
>Through a convoluted setup, User 2 can access User 1's local email folders which are stored on User 1's computer
>Total Email space taken by User 1's emails is ~85GB including the local folders (local folders ~40GB)
I would like to migrate them to O365. The problem is after converting the local folders in Thunderbird emails to a PST, how can I setup those emails so both can be accessed efficiently by both Users?
*I don't think uploading a massive 85GB PST file, then sharing the folders with the other user in Outlook would be the best solution.
Any suggestions would be appreciated!
