Users are being added to the meeting that I didn't add.

When creating a meeting, users are added that you did not specify when creating the meeting.

Please fill the template and provide more details/screenshots/steps to reproduce

[einstein88amt]

Computers in the domain. A user adds users to a meeting. Everything is fine. Only those he added are displayed. But in reality, other users may be added who weren't added but are in AD. And these users receive invitations.

Might be overlapping coming from the AD, or group/team included, that's pulling additional participants - but nothing that Talk app accidentally adds.
How was the meeting created? Via Talk UI or maybe Calendar event?

[einstein88amt]

A user creates an event in the calendar app, adds participants by name (for example, 200 participants), saves it, and everything is fine. Then, an invitation is sent to these 200 users and about 30 more users who weren't specified by the user.
The person who created the meeting sees that they sent an invitation to 200 users, while those who received it see these additional 30 users.

Hi @einstein88amt

Are you sure someone did not select a group? That has additional users?

[einstein88amt]

Yes, I'm absolutely sure. I didn't select a group. Only users by name. And it's always different: some users might be required to sign in, others optional, and in another meeting it's the opposite. There's no logic to it.

[einstein88amt]

Another thing: if you add a user to a meeting, you can't delete him later.

What can you tell me about my main problem?

What can you tell me about my main problem?

Honestly, I can't help with the main problem - it isn't reproducible from what's described here. Without exact steps and results, I think nobody can act on it.
