Removing duplicate emails from the BT server

Ladies and Gents, your assistance appreciated please:

Thanks to a mess-up when trying to migrate Outlook to a new PC, I’ve ended up with thousands of duplicated emails on the BT server.

Is there a way to remove these easily please?

Hi @Troy-Tempest

Welcome to the community.

There isn't a way to easily remove the duplicated emails other than going through all of them.

If you are going to delete them it may be best to do them in smaller batches of around 50, or create a new folder to move them to, and when moved, delete the folder and contents.
