Microsoft 365 Outage

Update as of 11:30am:
We are seeing restoration of email service for most of our customers.

From Microsoft:
We remain focused on addressing residual impact and ensuring reliable service restoration. We continue to assess recovery across various connection methods and closely monitor service health to verify sustained stability. At this time, we have no evidence of malicious activity associated with this incident. We will continue to treat this with urgency until full mitigation, and we will share a full Post-Incident Report with root cause and defense-in-depth actions after mitigation is complete.

Update as of 7am:
Microsoft 365 email is still disrupted, and Microsoft has not given a time for full recovery. Status below is as of 7:00 AM ET, Friday, November 13.

Current Status

  • What's down: Exchange Online mailbox access in Outlook desktop, Outlook on the web and Outlook mobile. Email delivery is delayed.

  • Also affected: features of Teams, SharePoint, Copilot and Microsoft Defender that depend on Exchange. Other MS365 services may also be affected.

  • Cause: a Microsoft server problem. Microsoft says there's no sign of a cyberattack.

  • Recovery: happening in phases, with some improvement, but not complete. There's no ETA.

  • Incoming mail: delayed, not deleted. Microsoft is reported to be holding delayed mail for retry for up to 48 hours.

  • Microsoft incident IDs: EX1550543 (Exchange) and MO1550821 (Microsoft 365). Public status page: status.cloud.microsoft

What still works:

  • Teams chat and meetings. Calendar invites and scheduling may fail, so start meetings with Meet now.

  • OneDrive and SharePoint files.

What to do:

  • Use Teams for internal communication.

  • Share files as OneDrive or SharePoint links instead of attachments.

  • Call customers and vendors about anything time-sensitive.

  • Post a short "email delayed" notice on your website or voicemail greeting.

  • Leave Outlook open. It may still show mail it already downloaded.

What not to do:

  • Don't reinstall Outlook, delete your Outlook profile or rebuild it. You could lose downloaded mail.

  • Don't reset your password. The outage isn't related to accounts.

  • Don't move business email to personal accounts.

  • Don't change your email or DNS settings during the outage.

Scam warning:

  • Expect fake emails and texts saying you need to reset or re-verify your Microsoft password because of the outage.

  • Don't click them. Microsoft and Orbis won't ask for your password.

  • If you already clicked a link or entered a password, contact us right away.ght away
