Microsoft (MSFT, Financial) said Monday that it has regained control of Outlook and Teams services, which have stopped working worldwide. The problems started in the morning and affected critical business applications. After they occurred, many office workers were no longer able to communicate. Before stabilizing, Downdetector collected over 5,000 reports of outages at peak times.

Microsoft released a fix and claimed in the evening that most users had access again, while some Outlook web users were still blocked. A full recovery should be possible by Tuesday. Earlier in the day, the company attributed the slower speed of its recovery process but said it was working around the clock to address other issues.

This outage comes after a year of massive global technical disruptions. However, unlike previous events such as the CrowdStrike IT outage this year, it did not have the same impact, crippling industries and causing billions of dollars in damages.

Such incidents have highlighted the dependence on cloud services as important business solutions. Organizations continue to face pressure to increase their efforts to ensure their infrastructure can withstand some impacts during an outage.

For businesses and users, Microsoft’s updates best illustrate the need to continually check service health portals for real-time recovery information. The tech giant also reiterated its intention to implement faster outage solutions to maintain user trust in its Microsoft 365 ecosystem.
