Can't get contacts window back if closed (red button) and a chat window is open.

Should really have a way to start a new chat with another contact. Big flaw.

Please add Cincinnati, OH as one of the USA conferencing city numbers. Currently all of our customers are in Cincinnati as well as our company, and the closest city defaults to NY, which is a long distance toll. Thanks!

Please add the GCC countries to this list: https://dialin.teams.microsoft.com/2ae99d4d-ed3e-402f-abdc-e04259ce0ec0?id=541815457

Please release a version where the integrated mic for MacBooks actually works on install.

microphone (internal or external (bluetooth) device) is not working although system preferences shows mic is working... Please fix this most basic feature!!

Micro not work on skype for business, micro privacy on Mac not have skype for business, camera have.
How can I add skype for business to micro privacy.

Mac only supports the entire desktop sharing which is making it extremely restritive and limiting it's use when you only have one monitor, and only one big/high resolution available.

When another application is installed which installs or updates a audio device driver, or a BlueTooth audio device is connected, SfB posts a notification to change audio devices based on this new device. This notification has two major problems: the notification is not obvious and is often hidden behind other windows; the notification brings SfB to a virtual halt - it will not even ring.

Please change SfB so it is less sensitive to audio device changes.

I can't see shared screens unless I quit a meeting/Skype and rejoin. It would be good to have this working.

Force Skype Product owner to listen to start-up sound on loop for 24hours

Show meeting content is not working for Mac - Catalina 10.15.2 , Skype for Business 16.28.140

Restart of Mac , Skype did not help to fix the issue.

Currently, you can't view the complete names of all participants during video conference in the macOS client, only initials.

Currently it's

Microphone
Ringing
Speakers

which is illogical - you almost always want Microphone and Speakers to be set the same, and then might choose different output for Ringing. I always have to stop and think after I plug in my headset which ones to adjust - should just be obvious by layout, such as:

Meeting Microphone
Meeting Speakers

Ringing

SfB for Mac shows status for contacts, including away time, however the away time doesn't seem to update automatically. It can be "forced" by selecting another contact, and then reselecting a contact of interest, but it would be good to have the update occur automatically.

Could you add a button in the control strip which leads to control buttons of the current conference call (camera on/off, mic on/off, share screen, option, hang off) and add duration and short topic?

Please turn off the startup and exit sounds. It's easily annoying enough for me to consider alternative software.

Please add the dark mode to the app, with Mojave iOS the dark mode is more easy to work.
