After a global outage hit many Microsoft 365 users for several hours, access and functionality of the services were restored on Wednesday, the company said.
Earlier the company blamed a "networking build" for the incident.
"We've identified and reverted a networking build that caused user traffic from the internet to Microsoft 365 services to intermittently fail, and are seeing early signs of recovery," the company said in a tweet earlier.
The incident revealed that the Cloud version of Microsoft Office is not infallible.
Some users took to Twitter to suggest a name change for the service.
"Time for a name change? Office363 perhaps?," said one user.
"Hope this gets fixed, we're currently doing a client demo," wrote another user who attached a crying emoji with the tweet.
Some users also reported that Microsoft's unified communications platform for workplace "Teams" was also down.
