Hi,
I am currently migrating my On Premises Exchange 2013 organisation to Exchange Online in a hybrid configuration and I have successfully migrated 200 users so far. I am now down to the final user, of which I am running into the same error each time that I try to perform the migration.
The user has both an primary mailbox (5.78GB) and an archive mailbox(79.07GB).
The move request fails on "Type="StoragePermanentException/MapiExceptionFolderHierarchyChildrenCountQuotaExceeded"
And the report is as below;

22:59:22 [LNXP265MB0586] Fatal error StoragePermanentException has occurred.
I have attempted to move the archive only onto Exchange Online and this is successful, the move request completes. I then attempted a move with -PrimaryOnly, this fails with the same error.
I have now moved the archive back on premises.
The error suggests that the move fails due to the folder count, and I am aware that Exchange Online has a limitation of 10,000 folders, however the primary mailbox does not exceed this.
Running the below;
Get-MailboxFolderStatistics -Identity joe-bloggs | Measure-Object | Select-Object -ExpandProperty Count
Returns; 4814
My on prem exchange version is; Version 15.0 (Build 1395.4)
Please help me resolve this issue.
I have already contacted Office 365 support, however I haven't had any success.
Thanks in advance.
