Hi there Kathy,

I understand how confusing it can be to see the same email show up multiple times. This usually happens when Outlook keeps downloading messages from the server because the account is set up as POP and the option to leave a copy on the server is enabled, or if there’s a sync issue with your mailbox. A quick way to start fixing this is to check your account settings under File > Account Settings and confirm if it’s POP or IMAP.

If it’s POP, try disabling “Leave a copy of messages on the server.” Also, make sure you don’t have the same account added twice in Outlook.

Can you tell me if you’re using POP or IMAP, and if this happens on all devices or just one?

Regards,

rez

This just started happening in my outlook in the last week or so also. I get two copies of every email in my inbox. I delete one and all is well. I don't get another copy the next time I open outlook. but this is VERY aggravating.

same thing just started happening to me this week.

I use a Verizon.net email which now comes through AOL mail. as the third-party provider every email appears twice in AOL mail and comes to outlook twice.

yes! Mine is At&T. But other threads say its either your pop settings are wrong or your message rules are incorrect. Well....mine is imap and nothing has been done to rules. they do not download twice everytime if I check thru yahoo, only everytime I download emails thru outlook.
