I'm wondering if anyone has programmed the following for Exchange
(2003):

* I need to be able to go into Active Directory and select a "team" of
individuals.

* I must be able to specify a leader(s) of the team (through A/D) which
can assign and modify tasks for the team.

*The leader(s) who create the tasks, must also be able to get the same
reminder that the assignees of the task will get X days before due
date.

Any help would be greatly appreciated.

Hello,

you could use the delegate feature of Outlook. While it is possible to set
this programmatically, it's also quite complicated.

Thank you for the response. I am familiar with the delegate feature in
terms of mailbox access and sending/replying on behalf of another
person, but am not aware of how it could be used to set up an assigned
task where both assignees and assignor get reminders. Would you be so
good as to provide a brief example?

Hello Tommy,

ok, misunderstood you.. in fact I were reading appointments when you were
writing tasks. This is not possible with tasks.

I think the best way to go is a global event sink watching the task folders.
This event sink is triggered whenever a task is modified. You could update
the relevant linked tasked according to your logic.

Hello,

I am trying to find information on how to display the list of people with
editor/author access to your calendar. I found a knowledge base article on
how to give someone access which involved creating an ACL object and
attaching it to the folder. But I cannot find any information on how to
review the ACL objects associated with the Calendar folder

Your post seems to imply that you're familiar with this kind of task, I was
wondering if you could point me to a code sample or a quick walkthrough of
which DLL/COM objects I need to use and what initialization sequence I need
to go through.

Hello,

if you are using .NET and have time till next week... I hope I have put some
code together over the weekend. I will post that on my website as part of
the InfiniTec.Exchange package.

If you do want to this yourself: I vaguely remember the kb you mentioned...
basically, you can use the AccessControlEntry and AccessControlList COM
objects to read the security descriptor from an Exchange item.... There
should be something in the SDK covering this.

Another option is to use WebDAV: Do a PROPFIND on the folder and retrieve
the http://schemas.microsoft.com/exchange/security/descriptor property. This
property contains the entire ACL in XML format. You can parse it from there.
However, the descriptor is an NT Security descriptor, so you must rebuild
the MAPI view from that. See
http://www.microsoft.com/downloads/details.aspx?FamilyID=2ae266f0-16b7-40d7-94d9
-c8be0e968a57&DisplayLang=en
for more information on that...

Best regards,
Henning Krause

I've just now gotten back to this issue. I managed to work around the form
based authentication that is setup on our OWA server. I've gotten to the
ntsecuritydescriptor property, but I'm not entirely sure what to do with it
now. I'm not really a windows programmer, and my first gut reaction would be
to un-base64 it to look at it. However I'm not familiar enough with C# to
get that done quickly :)

The document that you linked to is a nice description of how security works,
but I did not find anything in it on how to convert this base64 string into
something useful, like an ACL object mapping or something along those lines.

What do you do with the ntsecuritydescriptor once you have it? Is there a
.dll that I can use to map the string into an ACL object of some sort to
traverse? Or is there another way to read the string?
