Solution for guests accounts with an organisation account without Office365 tenant to be able to login at teams.microsoft.com
I have created several guest accounts following the instructions here:
https://docs.microsoft.com/en-us/microsoftteams/guest-access
Basically,
Enabled Guest Access in Office365 Admin Center
Added guest account through Azure Active Directory
a. Guest account received email Azure AD "You're invited to the organization"
b. Guest follows the "Get Started" link in the email to create a password
- Added guest to a Team through Microsoft Teams desktop application
a. Guest account received email Teams "You have been added to a team in Microsoft Teams"
b. Guest follows the "Open Microsoft Teams" link in the email to be sent to teams.microsoft.com
c. Guest is redirected to login.microsoftonline.com
d. Guest logins in using email/password from #2b
e. Guest is redirected to the Teams page and is able to work.
--
When the Guest tries to login directly to Teams - either through teams.microsoft.com or the Teams desktop application - they are redirected first to a login page (login.microsoftonline.com), then after login to an error page:
https://teams.microsoft.com/_#/licenseError?errorCode=UserLicenseNotPresentForbidden
The Guest can still login/access Teams following the "Open Microsoft Teams" link in the #4b email.
Workaround
If the Guest adds the "tenantId" indicated in the #4b/Open Msft Teams email to the Teams URL, for example: https://teams.microsoft.com?tenantId=1234567-89ab-cdef-0123-456789abcdef
Guest is redirected to login.microsoftonline.com
Guest logs in using username/password
Guest is redirected back to https://teams.microsoft.com/_?tenantId=1234567-89ab-cdef-0123-456789abcdef
Guest can now access the Team (without the UserLicenseNotPresentForbidden error)
This workaround only works through the Browser - it does not work through the Teams Desktop App, as it is not possible to include the requisite "tenantId" to login. Using the Desktop App always fails with UserLicenseNotPresentForbidden.
When the Guest is logged in using the correct "tenantId", the Teams menu (in the Browser) looks like this:

If the Guest clicks on the other account under "Your accounts" (abcdef-0123-4567-89ab-cdef012345), the Guest is redirected to the UserLicenseNotPresentForbidden error page.

It seems that a Guest has been assigned two different "tenantId"s (or Azure Object IDs), the first is the one created in step #2, the second is the one created in step #4. When the Guest tries to login without specifying the tenantId, login.microsoftonline.com defaults to the tenantId in #2 (which isn't authorized to access Teams).
I see no place in Teams, Office365 Admin Center, or Azure AD to manage these separate 'tenantId's or allow the Guest to login to Teams using the Desktop App.

If anyone is still hitting this issue, please respond in the comments section of this topic and let me know!
Thanks!

Also experiencing this issue, it's really annoying and makes us look unprofessional when interacting with clients.

I have been added as a Guest to a company's Teams. Since then I can no longer login to Teams using the Desktop App. The login page always redirects to the Guest login page. Hence the Desktop App is now useless. (Desktop for Mac)

I still have the same issue in my enviroment. Even though I have created guests accounts in my enviroment and sent invitation , they still are experiencing issues. at first they can login but then it shuts off and then at times they can not relogin to our tenant.

On web, it forces a logout, even when logged into Microsoft account wanted. Then you can choose a tenant/domain.
But on Android, it doesn't work in the app at all. Login just plain fails due.

When I open the guest link (I already have an organisational teams) but it won't show in my teams... It just keeps opening my own teams. In the application AND on the web!

This problem still happens with both android and apple clients. Have this issue currently and it's causing communications issues with a customer currently. We had to create a completely separate domain and Free Teams login account with separate credentials just to communicate with the client. Please fix this.
