Office 365 now offers an option to allow access to SharePoint Online site from only specific IP addresses.

To allow access to your SharePoint Online sites from specific IP address locations:

  • Sign in to your Office 365 administration center
  • Go to the SharePoint administration center
  • On the left navigation bar click on Device Access
  • Specify the IP addresses that you want to allow

Important: Make sure you enter your external (internet IP address). If you enter the wrong IP address you will not have access to all SharePoint Online sites including the SharePoint Administration center. In this case, you will need to open a ticket with the Office 365 support team to remove the restriction for you.

If you try to access a SharePoint Online site from an IP address that is not in the allow list, you will receive this message:

Microsoft makes frequent updates to Office 365.

In order to prepare and test these updates, an Office 365 tenant administrator can allow everyone or specific users to have access to these features before they are publicly available.

This gives you time to test and prepare the documentation to train/notify your users about the changes the upcoming changes in Office 365

It is very simple to activate.

  • Logon to your Office 365 Admin center with your tenant administration account.
  • Go to Settings/Organisations profile
  • Edit the release preferences to allow access to the first release

Note: It might take up to 24 hours to be activated.
