We are using RPC over SSL for Exchange 2013, we have a lot of syslog messages like this:
2014 Jan 27 10:15:17 WAAS01 java: %WAAS-CMS-4-700001: Failed to get the encryption/decryption key for EMAPI
So it looks like some clients aren't using the correct GPO settings and using the standard settings anyway (which is encrypted MAPI)
Is there any way to find out which client IP addresses are using EMAPI, I tried to debug the mapi accelerator and checked the errorlog.current file but there are too much information about every MAPI session so I can't find the ones which are using the wrong one.
Of course we have deactivated the Encrypted MAPI in the Accelerator Settings on our Central Manager.
I'm happy for every input I'll get.
