Subscribe to the Office 365 URLs and IP Addresses RSS Feed in Outlook


From time to time, we update the URLs and IP addresses that our services use.  This happens as a normal course of business (deploying new services, adding new capacity in datacenters or regions).  If your organization is trying to filter network traffic, you need to make sure you are allowing your users to these services.  We publish a feed that contains these updates.  One way to keep up-to-date is by subscribing to the feed in Outlook.

  1. File > Account Settings

  2. Select the RSS Tab

  3. Click New and enter the feed URL (https://support.office.com/en-us/o365ip/rss) and click Add.

  4. Click Change Folder.

  5. Select an appropriate folder and click OK.  I drop mine in the Inbox.

  6. Click OK.

  7. If you left it as the default feed name, you can enter From:”Office 365 URLs and IP Addresses” in the mailbox search bar.

    Facing below issue while adding the url in RSS Feed

    Outlook cannot download the RSS content from https://support.office.com/en-us/o365ip because of a problem connecting to the server.

      1. My understanding is the RSS feed has been discontinued.

    The RSS feed is still in operation. Given the rate at which this information changes it is very convenient. There are tools to convert RSS feed data into into code, which makes automating whitelist updates on the firewall easier
