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

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.

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?

I'd like to have the option to give a keyboard control to a guest user if the user have a Teams application installed. It worked a month ago but doesn't work anymore.
It works ok on Skype for Business

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.

Error switching tenants for guest access. My account has been invited to two different guest teams. One works, the othe fails during authentication.

I am asked to authenticate, then I wait, and in the end I get an "oops, something went wrong, please restart"

Instead of having to switch Tenant, why not add a section Guest where Teams from other Tenants are displayed while still displaying our home tenant Teams.

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.

As of the latest update, Guest users have almost full functionality in planner and teams in terms of creating and editing tasks. However the 2 missing pieces of functionality are:
-Guest Users Cannot add Comments to tasks.
-Guest users cannot upload a file to tasks, they can only upload from a link or sharepoint.

Please add these functionalities.

please add the ability yo use OneDrive, consumer versión, to it, no only OneDrive for Business, because, some of the customers have regular OneDrive and that's how they share some ítems with us.

When having direct communications with other organizations, it's an annoyance that you have to toggle between your internal org and external. You need to be able to quickly communicate with everyone that you would normally communicate with in a normal day. If this is the Business solution MS is going with, it needs to meet the immediate and obvious business needs.

Within every channel I would like to have the option to create a customer(guest) facing side and a non-customer facing side.

I want to collaborate on project scope and planning with the customer and collaborate on internal pricing, ordering, etc. with just my team, within the same project channel.

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

This should be fixed.

Whenever you accept an invitation to join a Team as a guest, you have to click Next through the getting started screens (four of them?). Add a Skip option on the first screen to bypass seeing the rest of them, if you are already familiar with Guest access (usually because you are already a guest in other Teams).

It does not appear that Guest users can be a presenter in a Live Event meeting. This is a key functionality as not all presenters will be employees.

BUG: Guests are not able to see additional tabs in a private channel / group chat

While guests can now join a Team meeting, there is no "promote to presenter" option to allow them to share their screen. Without this, I'm forced to fall back to Hangouts or Zoom.

ik want to be able to enable guest acces per team. just like you can per SharePoint SiteCollection.
