Hi, I'm having trouble being a guest through my work email in a vendor's Microsoft Teams account.

Background:

  • The vendor invited my ******@workdomain.com email address to their Microsoft Teams account.
  • Our company, workdomain.com, does not have any microsoft products/subscriptions/etc. We use Google Workspace.
  • I accepted the invite, set up 2FA, and can login to microsoft teams in a web browser.

It makes me login every day via a magic-code/link to my work email, and then checks my TOTP 2FA for it.

But I'd rather use the Microsoft Teams App for Mac (or for Windows). But when I use the app, and try to login, it brings me to a GoDaddy/Microsoft co-branded login page, and tells me I don't have an account when I try to login with my ******@workdomain.com email address.

When I look up help on search engines, everything seems to assume that I have a microsoft subscription for my workdomain.com -- but my company doesn't have any microsoft subscriptions.

I hear that we need to "unfederate" our domain with Microsoft. But the help documentation about that presumes we have a microsoft account. We don't.

How can I use Microsoft Teams apps (Mac, Windows, iOS, Android) as a guest?

Thanks,

Brendan

    Hi @Brendan C

    Regarding your issue, may I kindly ask a few questions to help understand it better. 

    • Could share your work email domain so I can give it a check is possible? (For example, if your email is [firstname]@workdomain.com, the domain would be workdomain.com.) 
    • Also, is the vendor who invited you able to use the Teams desktop or mobile app on their end?
    • Does everyone in the vendor's organization use the Teams desktop or mobile app, or do they all use the browser version?

    Hope to hear back from you soon.

    The behavior indicates that the work email domain is already registered and federated with Microsoft (likely via GoDaddy/Microsoft 365), even though the company actively uses Google Workspace. Because of that federation, sign-in from rich clients (Teams desktop/mobile) is being redirected to the GoDaddy/Microsoft-branded page, which then rejects the account. In the browser, sign-in is succeeding via a different flow (magic link + TOTP) that is not working the same way in the clients.

    This is not something that can be fixed from the end‑user side. It requires an administrator with control over the workdomain.com tenant to correct the domain/account configuration in Microsoft Entra ID (Azure AD) so that the guest account can be used consistently across web and client apps.

    Required actions (by an admin of workdomain.com or whoever controls the Microsoft tenant for that domain):

    1. Confirm which tenant owns workdomain.com
      • An admin must sign in to the Microsoft Entra admin center or Microsoft 365 admin center for the tenant that has workdomain.com registered.
      • If the domain was set up through GoDaddy/Microsoft 365, the admin may need to sign in via the GoDaddy/Microsoft 365 admin experience to reach the same tenant.
    2. Ensure the account is correctly provisioned as a guest in the vendor’s tenant
      • The vendor’s admin should explicitly invite the work email as a guest user in their Microsoft Entra ID, then resend the Teams invitation.
      • The user must accept the new invitation email and complete the sign‑in flow so that the guest account is fully provisioned in the vendor’s directory.
    3. Resolve conflicting account/federation issues
      • If the work email was historically used as a personal Microsoft account (MSA) or there is overlap between a personal account and a work/school account on the same address, this can cause sign‑in conflicts. In such cases, the personal MSA may need to be renamed to remove the overlap, as described in the troubleshooting guidance for overlapping Microsoft account and Entra ID identities.
    4. After admin fixes, sign in from Teams clients
      • Once the domain/account configuration is corrected and the guest account is properly provisioned, sign‑in from Teams desktop and mobile clients should follow the same modern authentication flow as the browser.
      • Use the same email address and complete any required MFA; the client should then allow switching to the vendor’s organization as a guest.

    If the organization does not know who administers the Microsoft tenant for workdomain.com, the domain owner (IT or whoever manages DNS/GoDaddy) must identify or become the Global Admin for that tenant to make these changes.
