I can't seem to stop a previously set email forward setting.

The setting was made in hotmail which is now Outlook but the name of the forwarding email was blank.

I have checked the box don't forward and it made no difference.

I have reentered the forwarding email address and left it there for 24 hrs, then removed it from the list and checked the don't forward check box.

Another 24 hrs later and emails are still being forwarded.

Any ideas are appreciated.
