Hello Friends:

I have Windows 11 Pro and Office 365 (Office Setup) installed on my PC and every time I open Word or PowerPoint I get the following message:

Select a certificate for authentication server:

Can you please tell me how to remove this message?

Thank you in advance for your help

Are you standalone Microsoft 365 user? You may contact your IT support to fix 

Hello @Kidd_Ip thanks for your reply. Indeed, I am an independent user and I do not have any IT support, that is the reason why I am asking for help through this medium. I have tried everything in my power, but I have not been able to solve this problem.
