Hi,@Claus Frauenheim
Thanks for posting your question in the Microsoft Q&A forum.
Based on your description, you want to know if TLS 1.2 is active and enabled by Exchange.
In the Exchange Server server, type regedit
and press Enter to open the Registry Editor.
- Navigate to
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols
. - Under
TLS 1.2
, select theServer
andClient
keys respectively. Check to see if their status is Enable.
I need more information from you about whether Exchange is enabled for TLS 1.2:
1.What version of Exchange Server do you have?
2.Can you provide a screenshot of the reported error message?
