Managing external identities to enable secure access for partners, customers, and other non-employees
Thank you for the response.
Unfortunately this doesn't resolve my issue.
I have tried logging in using a different browser (Chrome rather then Edge) and get the same issue. I have also tried in-private access. My account still gets associated with the Guest account for a different tenant. I am not able to log in to the account and see my organisations either.
I can (and will) go back to the service provider who has set me up as a Guest but I still dont see this as more of a Microsoft issue allowing this to happen rather than a supplier who may have done something wrong but shouldnt be allowed to take over my account this way.
