👋 Hi ​@SanuChacko, welcome to the Box Community! Thanks for reaching out about this issue. We’re glad to assist.

Regarding the invalid credentials error, does this occur when you're trying to log in as an admin? How many users are experiencing the same issue?

Looking forward to hearing back from you.

I am trying to log in as an End User, Jey.  All the provisioned users (5 at the moment) are having the same issue.

When I tested the Sign In from the Entra ID side, it worked fine.  But the same user cannot sign in using the regular taphandles.box.com site.

I may have solved this, Jey.  I did not realise that I had to create a Box.com user account for every Azure AD user I add.  Adding a user in Box, worked.

Dear ​@SanuChacko, thank you for your response and for sharing additional context around the issue.

I was about to ask whether the users already had existing Box accounts matching their Azure AD email addresses. Glad to hear that’s been resolved on your end.

If you need help with anything else, please don’t hesitate to reach out. 😊
