KB: 919169, Access Denied or 403 Forbidden When Creating Appointments in WebDAV/CDOEX

I saw another case on this issue and remembered that I hadn't put this on my blog yet.  If you are getting 403's when trying to create an appointment in another user's calendar using WebDAV or an access denied in CDOEX after installing our Send As hotfix (895949) then check out this article...

...You will have to open a support incident to get this hotfix....

Note from the article, "In special cases, charges that are ordinarily incurred for support calls may be canceled if a Microsoft Support Professional determines that a specific update will resolve your problem. The usual support costs will apply to additional support questions and issues that do not qualify for the specific update in question."

...In other words you should not be charged for this case if it is opened solely for the purpose of getting the hotfix, any additional troubleshooting or help may incur a cost...
