I am moving mailboxes from HOSTED Exchange 2013 to O365... I don't have direct access to the server to run powershell scripts etc.
I am considering:
- Make an "admin" email account and giving it full permissions on every mailbox...
- Leave it signed into Outlook 2016 to download an "Offline copy of all emails since forever".
- Export each mailbox from this mega-outlook 1-at-a-time.
- Bulk-import all PST's to Azure using AZCopy.
- Map+Filter all the archives and move them across to the O365 users.
Is there a better way to perform this task when I clearly don't have access to the actual hosted exchange server? I just have a web-admin panel which I can use to modify users and control permissions between them.
I was thinking maybe there is a tool out there which essentially does the above process, but in a more reliable fashion than Outlook (I see a lot of corrupted PST's and incomplete downloads in Outlook). I imagine that there are backup tools out there which do precisely this task of remotely downloading all mailboxes to PST's... or maybe there is another method altogether?
