About Exchange Online

Exchange Online is software (Wikidata Q11233179). It is an instance of software, per Wikidata.
Exchange Online is Microsoft's hosted email service, part of Microsoft 365. When it has problems, the effects are hard to miss: messages stop arriving, sending fails, or Outlook cannot connect. This page tracks current status and reported issues, so you can tell whether a problem is on Microsoft's side or yours.
Exchange Online handles business email in the cloud. It manages sending, receiving, mailbox storage, and sign-in for Outlook clients and mobile apps. Because so much depends on it, even a partial outage can disrupt a whole organization. The most common issues are delayed or missing messages, failed sign-ins, slow sync in Outlook or on phones, and errors when connecting to the server. Sending usually breaks first during larger incidents. Before reporting a problem, check a few things on your side. Confirm your internet connection works. Try signing in at outlook.office.com in a browser. If the web version works but the app does not, the issue is likely local to your device or cached credentials. Also check whether the problem affects multiple users or just your account.

When was the last mass outage?

Why are my emails delayed or not arriving?

Delays usually come from message routing on Microsoft's side. Check the service status on this page first. If status is normal, review your mailbox storage and junk mail rules, then try sending a test message to another address.

Outlook keeps asking for my password. Is that an outage?
