Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

In Communicator, there are a few logging options available in the Options dialog.

  • Under Personal:
    • Save my instant message conversations in the Outlook Conversation History folder.
    • Save my call logs in the Outlook Conversation History folder.
  • Under General:
    • Turn on logging in Communicator
    • Turn on Windows Event logging for Communicator

The first two options are fairly straightforward - they do what they say they do.

The last two are a bit more ambiguous. Here's my questions:

  • What "logging" does "Turn on logging in Communicator" enable exactly, and where is it stored?
  • I presume "Turn on Windows Event logging" sends some logs to the Event Viewer (eventvwr.exe) but what gets logged there?
  • How do these options differ from each other, in data collection and storage terms?

The General tab has a "More Information..." button in the Logging section, but that only takes you to a Privacy Statement - this tells you what Microsoft will and won't do with the information that is collected, but doesn't tell you what information is collected by which specific feature.

This question came from our site for computer enthusiasts and power users.

    
BTW: I'm totally okay with moving this to SF if that's more appropriate. –  Iszi May 20 '11 at 19:01
    
Why would this be better on Server Fault? I don't know much about Communicator, but it seems on-topic for SU. Is it server software? If you think it's better there, you could delete your question here and re-ask on SF. –  nhinkle May 27 '11 at 22:58
    
@nhinkle - Communicator is enterprise-level software - not your standard MSN Messenger. So, I figured the ServerFault community might have a bit more knowledge. Generally, when a question is mis-placed, I'd rather migrate than delete and re-create. –  Iszi May 28 '11 at 6:16
    
I think it's on-topic for SU, but if you really want it migrated to SF, let me know and we can do that. It does look like there are a bunch of questions about Communicator on SF, so it'll probably be an OK fit. –  nhinkle May 28 '11 at 7:59
