I am using one Shared Exchange providor now.
I switched to Microsoft 365 and want to have the same saved emails I have access to.
I exported a PST file from my old Exchange host.
I imported the PST file on the new host (Microsoft)
The size of the PST file is 3.3GB, and the size of the local data file is 3.3GB
When I go to Outlook on the Microsoft server, I see that only 326MB has been uploaded and won't go higher. A lot of older emails are missing. The same disk usage reflects in OWA, and has been at 326MB for hours.
I run into this issue EVERY time I am using a new Exchange Hosting Carrier.
-Do you have any suggestions for me to migrate?
-Is there a way to force the upload?
-I have Admin privs to my account, but not the server or Active Directory. This is shared.
