You Don’t Have Mail, as Microsoft’s Global Outlook Outage Affects Hundreds of Thousands of Users Worldwide

Outlook users from around the world began experiencing issues yesterday as their email client ceased functioning without warning. While the more commonly reported number appears to be 130,000 affected users, there are probably many more than that to be accounted for given the proclivity of Microsoft’s expanding global presence, and it seems that most media is only focused on checking Downdetector, but another similar service, isitdownrightnow.app, has perhaps a slightly more realistic number that Microsoft’s shareholders should probably be aware of. According to this site, there were over 1.4 million reports for yesterday alone and nearly another 1 million for today.

For those who felt excluded from the outage counts to the ones included in the aforementioned 130K count (seriously, if it was truly only that, then why is this getting so much media coverage and there are so many online threads asking what’s going on and why is MS having to provide so many updates?), rest assured Microsoft is working on the problem. There’s been technobabble that the average user is unlikely to understand, and make a Star Trek writer jealous of to paint a picture that somewhere, there were servers that failed, some unusual workloads were involved, and Microsoft has been trying to redistribute its traffic while attempting to bring back the downed servers. For some, Outlook is beginning to show signs of life, and the numbers, regardless of where you look to track, are starting to drop. With any luck, MS will get Outlook and its associated services, which can include Teams, although many have applauded not having to use it for a day, back up and running soon. It will be interesting to see if this outage causes more drama on Wall Street or ends up warranting a governmental investigation given the scope of businesses, agencies, and commerce it may’ve affected.

“We’re continuing our efforts to improve server stability to improve traffic flow. This includes adjusting traffic protocols, redistributing traffic, and applying strategic traffic blocking measures. We’re observing partial recovery across regions in which we’ve applied these adjustments; however, these actions aren’t resulting in sustained recovery, so we’re reviewing what additional actions we can take to improve overall infrastructure stability. “

We’re continuing to work on recovering our frontend servers while implementing further traffic optimization actions to improve service stability and increase capacity.

We’re seeing positive results for service stability and increased capacity as a result of our latest traffic optimization actions. We’re implementing these actions more broadly across affected regions as we seek to attain persistent recovery.

These are just a sample of the many posts on Microsoft’s social media account showing its efforts to bring Outlook back. The good news, it seems, is that according to research, cyberattacks are not to blame.
