Calendar "sync" error -18576

[Daniel Hochman]

I am having trouble with the calendar function of Entourage. I use:

Entourage 2004 version 11
OS X 10.3.5

Connecting to an Exchange 2003 server.

I get the following error for every appointment created on the Mac, and also
any meeting that is updated (accepted or declined) by another exchange user:

Could not synchronize record: {Name of Appointment} to Exchange server:
{username} exchange

Error -18576.

Email and Contacts sync flawlessly, and any appointment created on my PC
connected to the exchange server also syncs well. Functionally, this means
that on my Mac the only use the Calendar has is viewing my already made
appointments. I cannot create appointments without causing the error.

Any help would be appreciated.

Thank you.

I posted this question several days ago. Can anyone help me understand this
error?

Hello - Do you have URLSCAN installed on your network? Errors like this are
usually caused by blocking DAV commands that Entourage relies on.
