Trying to authenticate Microsoft Office on iMac using my corporate account

Good day dswoodard,

I see you are a new user here in Apple Support Communities - welcome! I hope we find you contributing often in the future.

If you are getting an error when trying to authenticate Microsoft Office 365, you may want to troubleshoot using this document in Microsoft's knowledge base - How to troubleshoot non-browser apps that can’t sign in to Office 365, Azure, or Intune

Thanks for using Apple Support Communities.

Safe computing.

try these steps :

1- install Google Chrome or any other browser

2- once you login to the website that asks for the certificate , capture the name of that certificate

3- open keychain access app, search with the name of that certificate in the search field of keychain access app

4- delete it , when you open Safari again it will ask you again to use that certificate and your issue is resolved

Have you asked Microsoft yet?

why should we contact Microsoft , its web browser related, so no need to contact Microsoft, i have just tried the steps above and its solved

Because it is a Microsoft product?

its a Microsoft service , a web service that supposed to work with all users and all updated web browsers, if you for instance create a new user in this iMac and try it you will find that it works normally, the issue is not with product , its with the certificate , which is related to apple.

these kind of errors you may face with all web services if we mess with the certificates.

What are you going on about, I asked if you had asked the manufacturer of the product, that is all. Too much coffee this morning?

Now you have fixed it you can stop!

actually i still didn't had any coffee.. i though you wanted explanation that all.. sorry if you got me wrong man.. have a nice day

Thanks to the response from mbehih121 my solution was:

1- open keychain access app

2- delete all microsoft entries

4- login in web browser

5- login to installed desktop 365 apps

Thanks, worked well!
