If your clients couldn’t log into Microsoft Teams on Monday (of all days), they weren’t alone.
Apparently, the $1.4 trillion company simply forgot to renew a critical security license.
Big oops, especially considering Teams has more than 20 million active daily users. It’s not clear if the issue affected every user, but many inside the Commercial Integrator offices experienced the same issue.
Microsoft notified the public via tweet at 9:19 a.m., identified the issue about an hour later and began deploying the updated certificate an hour after that.
We’ve determined that an authentication certificate has expired causing, users to have issues using the service. We’re developing a fix to apply a new certificate to the service which will remediate impact. Further updates can be found under TM202916 in the admin center.

By 4:27 p.m., the fix was successfully deployed to everyone, Microsoft said.

For one of the largest companies in the world, this is an embarrassing screw up, especially considering that Teams is the most popular unified communications app on the market.
Team’s competitors like Slack, Zoom and other are right on their heels, so Microsoft can ill afford many more mistakes like this.
From the Verge:
This was an embarrassing mistake for Microsoft to make for its flagship “Office hub” software, especially as the company started its own TV commercials for Teams recently. It’s also surprising to see Microsoft forget to renew a key certificate for Teams, especially when the company develops software like System Center Operations Manager to monitor for things like certificate expiration.
The good news is that this appeared to be a simple fix, and Microsoft was relatively quick to identify the issue. Hopefully, your Monday morning wasn’t too busy fielding service calls about this issue.
