Microsoft 365 outage

The ongoing Microsoft 365 outage is causing the Endex add-in to disappear from Office apps or become blocked for some users. The issue is on Microsoft’s side, and we expect it to resolve once Microsoft completes its recovery.

If Endex is still working for you, no action is needed.

Live updates

Status: ongoing. Microsoft has not yet declared the incident resolved. Latest first. For Microsoft’s own updates, see the Microsoft 365 status page.

    Outlook users locked out of inboxes

    Outlook users can’t reach their inboxes. The issue is first flagged in the Americas, then expands to any region. Microsoft says it is “redistributing connection traffic across our broader worldwide infrastructure to help balance the load.” Source

    Outage begins

    Microsoft 365 services that interact with Exchange Online and email start failing, including Outlook, Teams, Copilot and Defender for Office 365. Intune and the Microsoft 365 Apps admin center also go down. Source

If Endex is missing

You can try reinstalling it with the steps below. Until Microsoft’s recovery is complete, these steps may not be successful:

  1. Save your work, fully close the application, and reopen it.
  2. Go to Home › Add-ins, search Endex AI (or Endex for Outlook in Outlook), and select Add.
  3. If it doesn’t appear or won’t install, try the links below:

If the add-in is blocked

If you see a message saying the add-in has been blocked by your administrator or that your organization prevents installing Office Store add-ins, this is likely related to Microsoft’s outage.

Office dialog titled Add-in Error: This add-in has been blocked by your administrator. Contact your IT administrator for more information.
The error some users are seeing in Office.

If your company deployed Endex for you, it should reappear under “Built for your org” in the Add-ins window once Microsoft recovers. If it doesn’t, email us at support@endex.ai and we’ll coordinate with your IT team to check your organization’s add-in settings.
