There needs to be better management for viewing contacts in the chat section. It's really frustrating that even though I have placed different contacts into groups and then I collapse those groups that when I navigate away from the chat section and then come back that all of my groups get automatically expanded.

Ability to edit External User's information in Teams (in team members, for example): Name (if error was made during invite), Title, Company, Mobile number should be possible. If not in Teams UI then external user AAD information should be editable (or reflect information from the source AAD).

Or: External user should be able to change these in Teams profile per guest-tenant (settings)

Currenly changing external information in AAD does not show in Teams and there is no information about guest user.

I just spotted the new feature to add a custom status message to Microsoft Teams. GitHub introduced a similar feature recently. As a customer using both products it would be nice if you could sync those two statuses. Thus, users could manage their status at the preferred app and see other users’ statuses in both environments.

Add a feature to allow users to upload an image or animated gif to appear as a background behind their camera image. Using similar AI to the background blur effect, allow users to appear in front of a virtual background. This would be a fun feature that would drive engagement as well as allowing branding of corporate calls. Also, I want to appear with flames, dinosaurs and asteroids behind me to liven up conference calls.

Adding a contact to my favorites should automatically remove them from the 'suggested contacts' don't you think?

Create a custom group tag that only has certain members of the team to quickly get the same peoples attention

I've invited external users several times, (external users are allowed for Teams in the Office365 settings). The Teams app allows me to add users, sends them an email with a link, but when they click the link, launching their Teams app, an error pops up saying that they need to be invited to Teams. Although... they just clicked on an invitation link.

When on SFB you can see how long someone is offline for, this service on teams would be brilliant as you could see at a glance if someone is actively using teams.

It would be great to setup our availability in teams (like they have in slack). Like we could setup our working hours so we don't receive notification outiste working hours. Right now if I do not want to receive notifications (on my phone) I need to manually set me in away.

The contacts that have set their presence as "busy" or DND should not get notified/disturbed by the messages. If someone tries to send messages to a busy contact, MS Teams should ask if the message is really critical, with options "urgent, send now", "automatically send later when the contact is available", "dont send".
Its such a basic feature, it ought to be there

In large groups, users often need to quickly identify who is an owner. Presently, a user must go into the settings then "manage teams." I propose the use of "badges" or "icons" adjacent or partially covering their picture. This would provide a quick visual indicator of who is an owner. This idea could be further adapted to provide indicators of key contributers, subject matter experts, etc. The list of custimizable badges could be limitless.

Among the Status options in Teams, it would be good to have “Appear Offline” , in situations when I do not wish to be contacted (just like it was before in skype for business) !

Need basic features from Skype for business to organize contacts by who’s online and who isn’t

nickname functionality

Just like you can access the chat, email, organisation, video and call or message the person directly, it would nice to access their calendar from the persons card.

I miss the functionality of Skype where you can hide all contacts that are not online. The skype groups are much cleaner and consists only of my online contacts. The rest are either away or offline. This function is a must in Teams or else the groups will be cluttered with all the different statuses mixed. You can't get a good overview.

Add the support for getting a full list of session details via the "Get-CsUserSession" Powershell command like it is currently available for "Skype for Business Online".

Thank you in advance!

Skype has an option to "set your location". A similar option in MS Teams would be a great boon.
