Service Alert: Microsoft Email Delivery Delays — November 12-13, 2026

Microsoft is currently experiencing a widespread outage affecting Outlook, Exchange Online, and other Microsoft 365 services. As a result, emails sent to recipients using these services may be delayed until Microsoft resolves the issue.

If your mailing list includes a significant number of Microsoft email users, you may notice temporarily lower open and click rates while deliveries are delayed.

There is no need to resend your campaign. Direct Mail will automatically retry temporarily delayed deliveries until Microsoft's servers are accepting mail again. No action is required on your part.

For updates, visit Microsoft's Service Status page or Microsoft 365 Status on X. We'll also update this notice as more information becomes available.

Link Accounts for Other Apps and Services

Some Direct Mail features require connecting to other apps and services you use. For example:

  • Importing photos from your Instagram account
  • Importing contacts from a Google Spreadsheet
  • Sending email via your corporate Exchange account

When you use those features, you are prompted to link those external accounts to Direct Mail. The secret information (e.g. access tokens or passwords) that is used to link the apps together is always saved securely in your macOS Keychain or in our cloud vault.

You can view and edit linked accounts in the Settings window:

  1. Choose Direct Mail > Settings from the menu bar at the top of your screen
  2. Click the Accounts tab at the top of the window

The list of linked accounts appears on the left. To remove a linked account, select it and click - in the bottom-left corner of the window.
