Exclude folders from migration

• Separately add each Exchange Online folder or subfolder name.
• If you exclude a folder, the migration doesn't include its subfolders and any email messages in them.
• To exclude a subfolder, use the full path and separate the parent folder from the subfolder with a forward slash (/). For example:
  • If you want to exclude the subfolder Asia in the folder Travel, enter Travel/Asia.
  • If you also add Travel in the list, such as Travel, Travel/Asia, then all the subfolders are automatically excluded.
• To exclude a folder with a forward slash (/) in its name, replace each slash with an underscore (_). For example, to exclude Folder/with/slash, add it as Folder_with_slash.
• You can also exclude default Microsoft folders, such as Deleted Items, Inbox, or Junk email, and user-created folders.

1. Click Start scan.

   The status changes to In progress and the following information is updated in real time:

   • Users processed—Number of users that were scanned for all selected data types.

To stop a migration scan that's in progress, click Stop scan. It might take a few minutes for the migration scan to stop, and the migration scan process does not roll back.

After you successfully scan the data, you can click Re-run scan to scan any new and updated data.

If there are changes to previously scanned Exchange Online users or data, re-running the migration scan identifies and updates the migration scan report.
