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
But we got error
"Active Directory operation failed on WS2K16EXG. The object 'CN=IM Override,CN=Setting
Overrides,CN=Global Settings,CN=cyberThink Inc,CN=Microsoft
Exchange,CN=Administrator,CN=Configuration,DC=WS2K16EXG,DC=lab,DC=com' already exists.ADObjectAlreadyExistsException"
