Microsoft 365 administrator required

You'll need to be a Microsoft 365 administrator to follow these steps. If you're not a Microsoft 365 administrator, we recommend skipping this step, attempting to add the message source, and reaching out to your Microsoft 365 administrator for assistance if you receive a signin error when attempting to add the message source.

  1. Sign into the Microsoft 365 admin center at https://admin.microsoft.com
  2. In the lefthand menu, go to Users > Active Users
  3. Search for your user and click the matching row
  4. In the righthand drawer that opens up, click the Mail tab
  5. Under Email apps, click Manage email apps

You only need to create an app password if you're using two-step verification with your Microsoft 365 account.

  2. Once you've created an app password, enter it into the IMAP / App Password field in Sublime when creating the IMAP message source.
