Managing accounts in multiple Partner/CSP tenants
This is their response:
There’s no way to have one domain and user login for multiple CSP tenants. Each tenant must be associated with its own domain, which means a user who needs to access multiple tenants will need multiple logins corresponding to each tenant.
Are you not able to select a different linked tenant from your profile, top right of Partner Centre? You would then get logged in as a guest to another tenant. In destination tenant, someone will have to give this guest account correct permissions/roles in https://partner.microsoft.com/en-us/dashboard/account/v3/usermanagement
It's possible to use a guest account to gain access to certain areas of the Microsoft Partner Center CSP site. However, when you dig into Customers > pick a customer > Service Management > click on a service to administer (ex. Microsoft 365), the context is lost and that admin portal doesn't present information for that customer's tenant. I forget now if it presents information about the home tenant of the logged in account or the tenant of the CSP Partner portal.
I haven't tested myself. Does your guest account belong to the right security group, that includes relevant Microsoft Entra roles? You can see the security group for a customer at Microsoft Partner Center > Home > Customers > Customer List > XXXX > Admin relationships
I just tried again, and it didn't work. I set my guest account as a "Make this user an admin for partner companies: Full Administration", and I added the account to the GDAP group that grants Global Admin to a Test Customer. I then logged into https://partner.microsoft.com/dashboard/v2/home and switched to the CSP tenant. My guess account doesn't see the Customers Tile. I manually obtained the link for Home > Customers > Customer List > Test Customer and tried to access that with the guest account. That only displayed an error stating "No Access User doesn't have the necessary permissions to view the page." and only displayed "Service requests" on the left hand navigation. Clicking that generated "Something went wrong".
