Why generates a lot of certificate in my Azure AD connect server?

Hi, I am Rubiat.

I have an Azure AD Connect server which is running very well but recently I have found a lots of error application log which is event ID is 906. I checked those errors and found that it was related with certificate. Then I checked my certificates from mmc and got a lot of certificate which is issued by Microsoft PolicyKeyService Certificate Authority. Have anyone any suggestion why it is continuously generated?

Hello @mdrubiathaque-0645, those are certificates generated by the installation, updates and re-configuration of the Azure AD Connect Health agent. It is safe to remove the ones which have expired.
