I noticed in my employer's server logs that I'm getting a lot of strange requests in this format:
"PROPFIND /instmsg/aliases/[username goes here] HTTP/1.1" 405 335 "-" "-"

I'm not too familiar with PROPFIND, but I found out this is Outlook asking for information about the username (determined from email addresses / contacts). As you can tell, the webserver is currently responsing with 405 (Method Not Allowed) - does anyone know if there's a specific what I could or should be responding to these requests? Does IIS normally handle this (I have Apache)? Does request this normally get forwarded to a Microsoft Exchange Server (which my employer has)?
