We have some guest users, from different Home tenants, that have problems logging in to our tenant with MFA when using Edge web browser.

It works fine when they are using InPrivate in Edge, another device or another web browser.

When we check their settings in our Entra everything looks correct. We have not changed any policies or settings and it is not all the guest user from the same Home tenant the have this issue, for most of the guest users from the same Home tenants it works fine accessing our tenant with MFA while a few guest users from the same company/ Home tenant have this issue. 

It is almost as if there is a clash between their home tenant AAD user, Microsoft Edge, and the guest user in our AAD.

Does anyone have some recommendations och solutions to this issue?
