The process to authorize Microsoft Office 365 access for Atrium is straightforward and only takes ~5 minutes, but it does need to be completed by someone with global administrative privileges in Microsoft. The steps to do so are:

1. Log into Atrium (if you are logged in as a "[Guest User](/performance/docs/intro-to-the-guest-user-experience)" and see "Registered Accounts only" it is okay)
2. Go to this URL: [https://app.atriumhq.com/auth/msft-consent](https://app.atriumhq.com/auth/msft-consent)
3. Pick the account you’re going to authorize:

5. Grant org-wide admin access to read user calendars and mailboxes (if you don’t have global admin privileges, you’ll see a message that says “Need admin approval”).
