We have a user who had configured powerpivot data refresh jobs with his account. So, when he changed his password, his domain user account is getting blocked because of many wrong log-in try. Can I use management shell to display all power pivot data refresh jobs using his account credentials? Or what can I do with this issue?
How PowerPivot refresh configured? Was it setup with Secure Store? I doubt it but if so you will need to change the SSS credential in CA. Otherwise I would inspect the settings of the data connection PowerPivot is using.
