Hi Wayne,
Base on my knowledge, I don't think there is a tool could get all the client Operating Systems, include ExMon.
Using ExMon, administrators can view the following, but no client OS information:
-
IP addresses used by clients
-
Microsoft Office Outlook versions and mode, such as Cached Exchange Mode and classic online mode
-
Outlook client-side monitoring data
-
Resource use, such as:
-
CPU usage
-
Server-side processor latency
-
Total latency for network and processing with Outlook 2003 and later versions of MAPI
-
Network bytes
Do you mean that get all client outlook version ?Right?
If it is right, I recommend you can use Log Parser to analyse the RPC Client Access logs on the Mailbox servers.
The RPC Client Access logs are stored in the \Logging\RPC Client Access folder of the Exchange installation path, eg
C:\Program Files\Microsoft\Exchange Server\V15\Logging\RPC Client Access.
The log files are in CSV format and therefore can be analysed using Log Parser. Two of the fields of interest are:
- client-software
- client-software-version
More details for your reference:
Exchange Server 2013 Planning and Discovery Client Versions
