M365 hosting Tenant A and Azure AD for AAD Device on Tenant B and On prem

Jaganathan Krishnan 20 Reputation points

I have a scenario where "M365 is hosted on Tenant A with domain.com" and Azure AD for AAD Joined devices on "Tenant B with onmicrosoft.com" and on premises with "Domain.local" .

Problem-User need to login using different credentials in Azure AD joined devices and then Microsoft 365,issue is multiple logins.

Question-What different solutions available to simplify user login process or implement the SSO ,so that once user login with AAD joined device which in tenant A they should be login without credentials into M365 which is hosted on tenant B.
