Outlook is down and experts say don't touch your settings—a 'fix' could actually make your email problems worse.

Microsoft outage today: Microsoft 365 outage has disrupted Outlook email access and delayed messages, with problems also affecting Teams and SharePoint. MQTec Managing Director Moneeb Qureshi has warned users against resetting passwords or reinstalling Office, explaining why these fixes may not help while Microsoft's services remain affected.

Microsoft outage today: Outlook users not able to access emails during the Microsoft 365 outage should resist the urge to reset their passwords/ reinstall Office. These fixes may seem worth trying when an inbox suddenly stops working but they won't help as Microsoft's services are down.

MQTec Managing Director Moneeb Qureshi has warned users against making unnecessary changes to their Outlook accounts and software while Microsoft works to address the disruption.

Microsoft outage began on Thursday affecting "Exchange Online". Outlook users experienced problems accessing their mailboxes through desktop, web and mobile applications, while email delivery was delayed.

Outlook Not Working: Experts Say Leave Your Account Settings AloneA sudden Outlook error doesn't mean something is wrong with your password or computer. During a wider Microsoft 365 outage, the problem is beyond a user's control.

Qureshi advised against resetting passwords, rebuilding Outlook profiles or changing DNS, proxy and sign-in settings without a specific reason. Unnecessary changes could leave users with additional configuration problems even after Microsoft restores its services.

Checking Microsoft's public service status page is a better first step. Administrators can also look at the Service health section of the Microsoft 365 admin centre for updates.

Microsoft 365 Problems Extend to Teams and SharePointThe outage has affected more than email. While Teams chats, calls & meetings remained available. But calendar functions, scheduling & invitations faced problems.

SharePoint users could still access files, although external file sharing was affected. Copilot, To Do & Planner also experienced unreliable loading. Some Defender and Purview security features operated with limitations.

Microsoft's initial investigation found that an unexpectedly large number of servers had become unavailable and increased pressure on the remaining infrastructure. Microsoft said there was no indication of an attack.

Are Outlook Emails Being Lost During the Microsoft OutageDelayed emails are not necessarily lost. And email systems generally try to deliver messages again when the receiving server becomes available.

As per MQTec, Microsoft extended Exchange Online's normal 24 hour delivery window to 48 hours during the disruption, allowing delayed messages more time to reach recipients.

Qureshi advised users not to resend emails. But they should do so only after receiving a non-delivery report confirming that the original message failed.

How to Keep Business Communications Running As Microsoft Is DownMQTec recommends that businesses have backup communication arrangements rather than relying entirely on Outlook.

Emergency email accounts with another provider can help essential employees stay in touch during an outage. Businesses can also consider email continuity services that retain incoming messages until Microsoft 365 becomes available again.

Locally stored data is another option. Outlook cached mode allows users to access previously downloaded emails, calendars and contacts without a server connection. OneDrive files may also remain accessible when they have been synchronised and configured to stay on the device.
