Microsoft is investigating a known issue affecting Outlook for Microsoft 365 users and preventing them from creating Teams meetings using the app's ribbon menu.

The Teams Meeting add-in, as its name says, can be found in the Calendar view and it enables Outlook users to schedule a Teams meeting from Outlook.

Redmond's acknowledgment comes after customer reports who described experiencing this issue have been pouring on various online platforms, from Reddit to Microsoft's community website, for the last couple of years.

This issue occurs because the Teams Meeting add-in for Outlook becomes disabled, which leads to the meeting creation option being removed from the menu.

"When you attempt to create a Teams meeting in Outlook Desktop you find that the option is missing on the ribbon," Microsoft said in a support article published over the weekend.

While Redmond is still investigating the cause behind this ongoing issue, customers say that the add-in is likely disabled automatically after causing Outlook to crash, and no amount of repairing, uninstalling, and reinstalling the app can help fix this.

"The Outlook and Teams Product Teams are investigating this issue further to determine why the Teams Meeting add-in is being disabled," Microsoft said. "We will update this topic when we know the final resolution."

Hi, I was trying to search the forum, if I uninstall Microsoft Teams which is included in my Microsoft 365, is it ok or it may break some functionality in my other Office applications?

Are other Office 365 applications have dependencies on Teams? Thank you.
