Are You Getting Multiple Copies of Email in Outlook?

Seeing the same exact email two or three times instead of only once? Unfortunately, seeing multiple copies of email in Outlook is a common issue when your mail client (ie. Outlook) is setup to leave copies of your mail on the server. Outlook compares the headers of emails already on your computer with those on the server – if they differ, or have been corrupted for some reason, your Outlook will download the email again.

How can I prevent receiving the same email over and over?

The only foolproof method to prevent Outlook from re-downloading the same email is to tell it to stop leaving mail on the server.  Here’s how to do it in Outlook/ Outlook Express:

  • Browse to your email accounts settings (Tools -> Email Accounts – View or Change Existing)
  • Click on your email account and hit “change” or “properties” at right
  • Click on the “more settings” button
  • Under the “advanced” tab you’ll want to uncheck “leave copies of messages on server”

More solutions

Some other solutions we’ve encountered in case the above doesn’t work for you:

  • If you are using aliases (forwarding) for your email, make sure that the alias is not setup to check emails in a different profile
  • Move all your inbox messages to a new folder
  • Create a new profile/ pst folder

The advice above is all well & good but this issue (receiving multiple copies of emails – Not sure if we are sending in multiples!) has only just begun to occur. What´s more no settings have been changed although I have had updates for Windows 10! Could this be the cause & what would be the solution? System Restore?
I made the change yesterday and unchecked the option for leaving the messages on the server. Today I am not receiving any emails to Outlook. Has this change affected my ability to receive emails??
I have the latest version of Outlook and I am getting the same email from the same person every 20-30 minutes. Please tell me how to resolve-what did I do? LOL
Did what was suggested. Advance was not set for leaving copy on line. Getting 2 to 4 copies but not on all email accounts. I have also heard that I was sending an email more than once at the same time.

I cant even find ‘tools’
