When collaborating in a Team with certain people it would be nice if you could limit adding guests based on their domain. For example, I create a Team to collaborate with Contoso, I want to be able to add only people with the contoso.com domain. This will prevent accidental mixing up of different companies in a single Team.

Allow Guest to only view specific channels in Microsoft Teams. Especially when a part of channel in a project is led by Vendors.

Instead of having to select tenant, pls have all teams in one list and mark those in other tenants with a globe. Much like Yammer.

Also have notifications displayed in the same manner. I.e one experience for everybody with no need to switch tenants.

It would give everybody a clearer and easier way of keeping track of all your teams, no matter of where they reside.

currently if we want any team to have guest access it has to be turned on globally. we want to have it turned off by default and still have ability to allow for designated teams. currently we have to catch each team when created and turn off and then turn it on for designated teams. this is a cumbersome process.

When an external Guest is added to an existing team, the guest is not able to access the Wiki.

Error message is "It looks like your SharePoint doesn't allow adding Wiki tabs"

We known that guest cannot view the org of company, we also need to prevent guest to view the member's email address in Teams. It's a necessary security feature as well.

Please add audit functionality for Teams for who admitted people from the lobby and what time they were admitted.

This allows us to add who audit who was in a meeting from outside our org or federated orgs.

When guest users try to access notebooks they receive error messages.

This should be fixed.

When having to switch to another tenant in teams for one of my clients the switch over takes too long. It also leaves you blind to activity on any other client unless you were specifically @ mentioned which almost entirely defeats the purpose. It makes you have to switch between them all constantly and this takes a long time. It becomes difficult to justify teams use this way

I suggest removing the need to flip between accounts to see news feed, chat, teams and channels for each account. Once you're logged to all your accounts you should be able to see all of these from the same area regardless what account they're part of. Flipping between accounts to see these things is inefficient and also is problematic with notifications.

Would like to use Teams as a platform to interact with coworkers and employees that don't have a company email or Office 365 account. The only thing preventing this from happening, is that their private/personal email addresses are shared with others. To protect their privacy, I'd like the ability to hide their contact info from other guests.

I would like to block the guest access on organization-wide while allowing the guest access to only the certain team in Teams.
Slack have similar settings, so it would be great if Teams would have the feature.

Visualization with multi account (diff organizations) is not very good. It takes to much time switching the organization, and back again. Please make all the accounts visible at any time - in a folder og tab view (or any better idea :) )

Where a guest is added to a Team from another organisation, their email address is visible to all other team members, and they are identified by the first part of their email address (before @).
For some types of collaboration it would be good if guests could be added in a way which give them aliases, so they can't see each others' email addresses.

When sharing the screen, in fact the screen is not shared but the application is shared with the other side. It means, if the host user drags other application over the shared application in that screen, the guest still sees the older application not the one dragged over. Every time, the host should stop sharing and re-do sharing if they want to share a new application.

It has been brought to my attention that guests can't see avatars at all. Please make this an option (or if one exists that I do not know of please tell me).

Is it possible to customise the email template that is sent to guest when they are added to a team?

for example, if we wanted to add in a sentence about our company's acceptable use policy, or something to adhere too?

The limitation of 5 Guest access maximum per paying user is absurd : On one hand you provide Free TEAMS and on the other hand if we want to create Teams with many external people it is blocked. At least we should not have a limit for external users that are Office 365 User on another tenant as they already pay for teams!!! Otherwise please provide a GUEST subscription that we can buy for our guests. I don't understand this limitation as we can share document without limitation with everyone!!!

It will be cool tho have the option to upload my photo profile to my GUEST account, not just my name.
