We migrated exchange server 2010 to 2016.We have renewed our SSL certificate so thumbprint has been change.anyone have any idea how to we can change thumbprint for Instant Messaging I Exchange 2016 OWA and Skype for Business 2013.

We tried below cmd line with new certificate thumbprint,

New-SettingOverride -Name "IM Override" -Component OwaServer -Section IMSettings -Parameters @("IMServerName=WS2K16SFB.lab.com","IMCertificateThumbprint=0F4E220212440250F92B9CEA7FD8D40BA51374B0") -Reason "Configure IM" -Server WS2K16EXG

Overrides,CN=Global Settings,CN=cyberThink Inc,CN=Microsoft

Hi @JeminPrajapati-1970,

Have you decommissioned Exchange 2010 server in your environment?

According to your error message, it indicates that the value for the “CN = xxx” is taken from the alias property of the user being migrated from the old exchange server. In this case, we recommend you compare your AD properties between two servers. You can also try to delete the old “IM Override” and renew another name.
