Office 365: Set up email forwarding (University Only)

 This article is only for Duke University users. By policy, Duke Health users cannot forward their email to another email provider.

This article provides information for Office 365 users who wish to forward their email to another email account.


Important things to know about forwarding your Office 365 email to another email provider

  1. When setting up forwarding, you have the option to also keep a copy of that email in your Office 365 account. We want you to be aware that if you choose to keep a copy, you will want to occasionally keep an eye on your Office 365 account to make sure you do not go over your email quota. Having a backup copy in your Office 365 account may be useful in those situations where you are not sure if an email was forwarded to your other account.
  2. In Office 365 you can choose to forward your email to only one external email provider.

My forwarding to Gmail stopped working when we switched to Office 365 - how do I fix it?

Before Office 365, there were two ways to forward your email to your Gmail account.

  1. Use the university email forwarding tool at http://www.duke.edu/online. 
  2. Use Gmail's built-in POP3 functionality to download a copy of your DukeMail into your Gmail account. Google calls this functionality Mail Fetcher.

Office 365 does not support POP3 functionality, so if you set up your DukeMail to connect to your Gmail account using that option, it will break when you are migrated to Office 365. You may see a red warning bar appear at the top of your Gmail web interface, and you'll find that copies of your DukeMail messages no longer show up in your Gmail inbox.

To fix it and continue forwarding your Duke mail to Gmail:

  1. Turn off your POP3 functionality in Gmail. For instructions on how to do so, see https://support.google.com/mail/answer/21289?hl=en&ctx=mail
  2. Turn on forwarding in Office 365 to your Gmail account.
