Hello All,
I'm stuck in a very strange problem and need help.
I imported pst file to m365 exchange using lifecycle data management console (https://compliance.microsoft.com), i sent as usal my pst using azcopy; i validate my mapping file and then i launched import to 365, as I maded it several times.
After a long time (my pst are quite little (12 gb in two files) i got an import error.
The same error appears on log with each pst.
Many thanks for helping me.
Best regards.
Herve

Locked Question. This question was migrated from the Microsoft Support Community. You can vote on whether it's helpful, but you can't add comments or replies or follow the question.
I've not yet had to do another import, but on my support ticket they said it was now fixed.
Are you still having this issue?
Everything looks good on my end with the 365 import service among other things.
I'm also unable to find incident EX450352 anywhere under service health or via Google.
EDIT: Just to confirm, it still finished with a 'Completed with Errors' status, and nothing was imported. It still gave me a completely useless error of:
| PST Filename | Target Mailbox | Import Status | Error | Total Items | Item Imported | Target Folder | Skipped Item Count | Last Failure | Total Item Size | Imported Item Size |
|---|---|---|---|---|---|---|---|---|---|---|
| test.pst | *removedforprivacy* | Failed | Unknown | 0 | 0 | 0 | System.NullReferenceException: Object reference not set to an instance of an object. | |||

ORIGINAL POST: Thanks Hervé. I'm pretty sure my account has all of that anyway. However, I've followed your steps, and I shall await to see if in another 2 hours the exact same issue occurs again. I still also have my open support ticket since the MS Support hasn't come back to me yet.
Hello Sean
I added to my process impersonation :
New-ManagementRoleAssignement -name impersonationAssignementName -Role ApplicationImpersonation -user myadmin.mydomain.com
Here are my whole process right before migration :
Connect-ExchangeOnline
Enable-OrganizationCustomization
New-ManagementRoleAssignment -Role "Mailbox Import Export" -User "******@mydomain.com"
New-ManagementRoleAssignment -Role "Mailbox Import Export" -SecurityGroup "Organization Management" -Name "Import Export Org Management"
New-ManagementRoleAssignement -name impersonationAssignementName -Role ApplicationImpersonation -user myadmin.mydomain.com
And check with
Get-ManagementRoleAssignment –Role "Mailbox Import Export" | FL RoleAssigneeName, Name
My process came from https://lazyadmin.nl/office-365/import-pst-file-into-office-365/ (solution 2)
Hey Hervé,
Please can you DM me the fix? I don't quite understand what you've done? I've done migrations for 5 years and never had an issue until now, so I guess its a Microsoft change as I always follow the same steps! I notice their article for imported was updated this month which suggests they changed something backend too....
I always set the UPN and email address etc to the correct domain address to match both the exported PST, but also the PST mapping file, so not sure what could be wrong.
