Hundreds of Microsoft 365 users have expressed frustration and confusion with unexplained issues with software programs including Outlook and Teams.

X has been flooded with posts from baffled users who are unable to use the popular applications. 

“Can someone explain why this is occurring when I use my Android Outlook?” a woman inquired, posting a video showing a blank screen as she attempted to launch the email app on Monday evening.

‘OMFG I hate Microsoft Word!!!! Has it always sucked this bad?’ another outraged user echoed.

“That’s something new… Outlook seems to have a memory leak or an issue – it took up around 5Gb of RAM before I had to force close it,” a man commented, sharing a vague notification about his session having unusually high memory usage.

According to Downdetector tracking, Microsoft 365 complaints spiked just before 7pm EST with over 1,400 reports.

According to the tracker, about 60% of these grievances relate to Outlook, 26% involve Exchange, and 14% are concerning the general website.

Microsoft has addressed the outages, sharing a service status update reading: ‘We’re having issues, but we’re working on it.’

The company shared on X they are investigating reports regarding several services, specifically Teams and Exchange. 

The firm specifically indicated issues with Microsoft 365 – which Exchange falls under – at 5:45pm EST. 

‘Users may experience degraded functionality for some Microsoft 365 apps,’ the notice reads, marking a red ‘x’ to indicate its current status.

‘We’ve confirmed that all services are recovering following our mitigative actions. We’re continuing to monitor recovery and in parallel confirm details regarding the impacting update.’ 

The software giant also noted that Teams is down.

Microsoft noted users ‘may experience intermittent crashes of the Microsoft Teams desktop app.’ 

‘We’ve initiated the deployment of the new build version containing our fix, and anticipate it will complete by our next scheduled update on Wednesday, June 18, 2025, at 6:00 PM UTC, remediating impact for all users,’ the statement reads.

However, this warning pertaining to Teams troubles was first rolled out on May 26. 

The company said that Outlook ‘is up and running,’ despite people complaining about not being able to use the email service online. 

On Friday, the Microsoft 365 team published a possible ‘workaround’ to Outlook crashes

On Friday, the Microsoft 365 team published a possible ‘workaround’ to Outlook crashes. 

This online document was updated on Monday morning, before the internet was swarmed with Outlook-related complaints. 

‘When you open or start a new email, classic Outlook crashes. This issue occurs because Outlook cannot open the Forms Library,’ the company wrote.    

‘This issue can occur for Outlook on all Microsoft 365 Office channels. The emerging cases for this issue are on virtual desktop infrastructure (VDI).

‘This issue has been escalated for investigation. We will update this topic when we know more.’ 

Listing out step-by-step instructions to the potential quick fix, the support team suggested creating a FORMS2 folder. 

Microsoft 365 is used by more than two million companies globally – with more than a million business customers in the US, according to Statista data from February.
