Keep up to date with Office 365 IP Changes

It’s quite common for administrators to get caught out by IP changes in the Office 365 pool, and to find a service becoming intermittently inaccessible due to the addition of an IP address range to the pool of IPs used by an Office 365 service.

Microsoft publish an RSS feed to make this a bit easier for admins to follow, however I wanted to take this one step further.

Using Microsoft Flow (or IFTTT if that’s your bag), you can configure an event so that an update to an RSS feed prompts an action. That action could be to send an email, to update SharePoint or Yammer, or to update a Spreadsheet (amongst others). People consume information in many different ways, and this is one way to customise the delivery of this information to suit the way you work.

As an example, I want to send an email to myself every time a change is made to the Office 365 IP address RSS feed. To do this, I have logged into Microsoft Flow and have created a new Flow for myself.

The trigger event will be an RSS feed to look for changes to https://support.office.com/en-us/o365ip/rss

Microsoft Flow RSS Trigger

The action event will be to send an email through to me to warn me to update my firewall:

Microsoft Flow Send an Email

That’s all there is to it! You can choose any action you desire when an update is made to the RSS feed.

Hope this helps!
