Dear Team,

We are unable to install outlook in my Laptop. it showing below error

Request Id: Removed PII

Correlation Id: Removed PII

Timestamp: Removed PII

Message: AADSTS50020: User account 'Removed PII@m*******.com' from identity provider 'Removed PII' does not exist in tenant 'Removed PII' and cannot access the application 'Removed PII'(Microsoft Office) in that tenant. The account needs to be added as an external user in the tenant first. Sign out and sign in again with a different Azure Active Directory user account.

Please help to resolve this issue

Thanks

    Dear @Lokesh-Matrix,

    Thank you for reaching out to the Q&A forum! 

    For your situation, I will explain detail to you can clarify:  

    Microsoft 365 applications like Outlook are managed by specific organizations (called tenants). 

    • You're trying to use Outlook that belongs to P******* S*******, but you're signing in with an account from M******* P*******. 
    • Since your account is not recognized by Percept’s system either as an internal user or a guest, access is denied. 

    So, if you want to be able to sign in and use Outlook, you’ll need to contact their IT administrator from PSP Ltd and ask them to add your account (@matr....-proc......com) as an external (guest) user in their Microsoft 365 environment. 

    Screenshot of the invite external user menu option.

     

    • Please enter the guest’s email address => (Optional) Add a display name => Send the invitation  

    Screenshot of the invite external user Basics tab.  

    • You will receive an email with a link to accept the invitation. Once accepted, his account will be added to the tenant as a guest.

    • On the IT admin side, the guest’s email address will appear in the user list with the user type marked as "Guest". 

    For more detail you can infer this article: Quickstart: Add a guest user and send an invitation - Microsoft Entra External ID | Microsoft Learn 

    Once again, thank you again for raising this issue; it’s helped broaden my understanding. I hope you understand that I want to help as much as I can within the scope of this forum.      

    Looking forward to hearing from you!
