Exchange 2019 CERT renewal with scripting
Hi, we understood that CERT renewals using Exchange Admin Center are no longer possible after CU12 for Exchange 2019, we're currently using 15.02.1118.026. Thus, we're bound to use scripting, which is really combersume. In the first line we state "Get-ExchangeCertificate -Thumbprint ...5BE9". This is the thumbprint of the CERT to be renewed. But we have to confirm "Current certificate: '...EEE7. Replace it with certificate: '...633A" which is not as intended. What to do? The script does not do what is specified. Thanks for any help, Marcel
