How To Stop Duplicate Incomig Emails In Outlook

I have Outlook 2010 and recently copied my emails from my old PC on to my Laptop.

I receive duplicate emails of all incoming emails. Please advise how I can prevent this from happening.

Does this help Outlook is downloading thousands of old/duplicate emails from a - Microsoft Community

Thanks for the info but it did work. I receive emails I get two emails from the same source i.e each email received is duplicated

Managed to sort out my problem. Incoming Mail settings set up twice. Removed one and mail no longer duplicated

Thanks for getting back with your solution Howardc.
