URLscan ini file exceptions

I installed  the IIS URLscan extension this morning, as recommended in Scott Guthrie's blog post

This promptly stopped Outlook Web Access from working. The URLScan log file showed me what was wrong. I had to loosen up from the default position by setting:

AllowDotInPath=1 in the [options] section

adding the following verbs to the [AllowVerbs] section


SEARCH
SUBSCRIBE
PROPFIND
POLL
BPROPPATCH

and commenting out

Translate: in the [DenyHeaders] section;
:  (Don't allow alternate stream access) in the [DenyUrlSequences] section. This was causing any email subject with a colon (Re: your message) in it to be rejected;
.. (Don't allow directory traversals ) in the [DenyUrlSequences] section. This was causing email subjects ending in . to be rejected.
