When will Microsoft Outlook outage be fixed? What we know.

Updated on Thursday, Nov. 12 at 7:53 p.m. ET / 4:53 p.m. PT — Microsoft has issued a new update stating that the servers they’ve brought back online may become unresponsive again when they receive traffic. The company is currently investigating the issue, though in the meantime it’s limiting the types of traffic going to these servers in some locations.

Updated on Thursday, Nov. 12 at 6:23 p.m. ET / 3:23 p.m. PT — Microsoft states that it is bringing some servers back online, and “they remain stable so far.” Users should expect a “gradual recovery.”

“We’re also shifting traffic to alternate routes wherever possible and observing limited recovery,” Microsoft wrote in an update on X. “In parallel, we’ve streamlined the process of returning the remaining affected servers to service.”

Microsoft is experiencing a significant global outage today, resulting in Outlook, Teams, Copilot, Microsoft 365, and other popular services going down for an extended period of time.

While Microsoft deals with the outage, many users have been left wondering, “Just when will I be able to access my emails, messages, and calendars again?”

Unfortunately, Microsoft has yet to share an estimated timeframe in which users can expect Microsoft 365 products to be up and running again. In an update posted to X at 4:00 p.m. ET, Microsoft struck an optimistic tone, saying that some affected servers were already back online. But by 5:09 p.m. ET, the company acknowledged its services were still down.

“We’re opening all available pathways to restore service, as our actions taken thus far have not provided the anticipated relief,” the company wrote on X and a status page.

This isn’t the first time Microsoft services have experienced outages. Most recently, Microsoft Outlook went down on Aug. 31 of this year.

That Aug. 31 Outlook outage began around noon, and according to our reporting at the time, service had been fully restored by 11 p.m. ET that night. If Microsoft is able to deploy fixes in a similar timeframe, then today’s Microsoft Outlook outage should be fixed around 11:30 p.m. ET tonight.

However, the timeframe for this particular outage could be very different, depending on the issue involved and what Microsoft needs to do to get services up and running again.

Mashable reached out to Microsoft with questions about the outage, but the company had not responded at the time of publication.
