CertificateThumbprint attribute does not found in Exchange Online

Question

CertificateThumbprint attribute does not found in Exchange Online

Abhishek Goyal 131

I used the ExchangeOnlineManagement module for using exchange online service via Powershell. The version of the module I used is 3.1.0

According to Microsoft documentation, Connect-ExchangeOnline cmdlet provides CertificateThumbprint attribute for app-only connection.

https://learn.microsoft.com/en-us/powershell/exchange/app-only-auth-powershell-v2?view=exchange-ps

But when I use Connect-ExchangeOnline cmdlet using CertificateThumbprint attribute it gives an error.

It's available and working fine here. Which version of PowerShell are you using? Don't load the module in the EMS, open a new Windows PowerShell (or PowerShell 7) console.

If you've just installed/updated the Exchange module, restart the console for best experience.

Actually, I used Powershell 7 on MacOS. CertificateThumbprint attribute works randomly. Some days ago, It was working fine, but now it does not work. I follow all your suggestions. But also it did not work

I'm not sure this parameter is supported on MacOS, as it relies on the Windows methods, afaik. Try using -CertificateFilePath/-CertificatePassword instead?

Hi @Abhishek Goyal ,

Agreed that it might because that you are on MacOS. Have also tried asking it via the Feedback option available at the end of this document to see if we can get any more information:
