MAUTHMOVERAPP

Why it happens

This failure code appears in the ResultCode column of Migration Manager scan and migration reports. It means the Microsoft 365 migration app needs to be authorised in the source account, such as Dropbox or Box.

Where you see it, and what it affects

Look in the detailed reports for Migration Manager cloud migrations, which cover Google Drive, Dropbox, Box and Egnyte. Download scan reports from the Scan tab and migration reports from the Migration tab. The detailed report is TransactionItem.csv, and its ResultCode column holds the file-level failure code. Requested reports are under the Recent actions icon at the top right for seven days. Reports expire after 90 days.

How to fix it

1. 1

   Step 1

   In the SharePoint admin center, open Migration center and select your cloud migration project.

2. 2

   Step 2

   Go to Project Settings > Project Details and disconnect the source.

3. 3

   Step 3

   Reconnect to the source so the Microsoft 365 migration app is authorised again.

4. 4

   Step 4

   Rerun the migration task.

Check that it is fixed

• Download the migration detailed report for the rerun task from the Migration tab.
• In TransactionItem.csv, the ResultCode column should show None for items with status Success, and no MAUTHMOVERAPP rows.
