SUBMITTING FAILURE Failed to Submit the Job to Server: Unknown failed reason when submitting a job. 0x01610002

A Migration Manager agent could not submit a migration job to SharePoint, which Microsoft links to antivirus software on the agent machine.

Why it happens

Microsoft says to check antivirus software on the agent machine (the Windows computer running the Migration Manager agent). It can interrupt migration traffic.

How to fix it

1. 1

   Step 1

   On the agent machine, open your antivirus application settings.

2. 2

   Step 2

   Add microsoft.sharepoint.migration.clientservice.exe and microsoft.sharepoint.migration.mthost.exe as exceptions.

3. 3

   Step 3

   In the SharePoint admin center, go to Migration center and rerun the failed task.
