Hi @UIG Technology Admin , there are several reasons why an external user might receive an error when accepting an invitation.
One possible reason is that the invited external guest user's email may conflict with an existing Contact object, resulting in the guest user being created without a proxyAddress. This is a known limitation that prevents guest users from redeeming an invitation through a direct link using SAML/WS-Fed IdP, MSAs, Google Federation, or Email One-Time Passcode accounts.
To unblock users who can't redeem an invitation due to a conflicting Contact object, you can follow these steps:
- Delete the conflicting Contact object.
- Delete the guest user in the Azure portal (the user's "Invitation accepted" property should be in a pending state).
- Reinvite the guest user.
- Wait for the user to redeem the invitation.
If this does not solve the issue, please provide more information about the error message or any other relevant details so that I can assist you better.
Please let me know if you have any questions and I can help you further.

Thank you,
