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.

Great ways to grow your mailing list

This help article is for an old version of Direct Mail.

Here are some suggestions on how to find new subscribers for your mailing list:

  1. Create a subscribe form and place it on your company's website
  2. If you sell a product online, give the customer the option of subscribing to your list during checkout. Use our Integrations window to connect Direct Mail to your e-commerce website.
  3. If you sell a product offline, encourage customers to sign up for your mailing list in store. Running our Stamps app on an iPad is a great way to get signups.
  4. If your business has a Facebook Page, add a "Newsletter Signup" tab.
  5. Add forward to a friend and other social sharing links to your email campaigns.
