The settings on the tab for "delegate" was not properly stored.

Question

Hello group,
I try to write it in english - but it is a try only *g
Since last week I can´t set or delete any user or groups from the delegate tab.
Only User in the IT OU can set delegates. I´ve compare the users with acldiag and I can´t see any differnce.
I´ve try to move the users to the IT OU but the problem is the same.
New Users have the same problem. I´ve copy a User that can set delegates but the copied user can´t set it. 
Die Einstellungen auf der Registerkarte für "Stellvertretungen" wurde nicht
korrekt gespeichert. Liste zum Senden im Auftrag kann/können nicht aktiviert werden.
Sie besitzen nicht die erforderliche Berechtigungen, um diesen Vorgang mit diesem Objekt auszuführen.
I´ve translate the error message with google language tools.
The settings on the tab for "delegate" was not
properly stored. List to send in the order can or can not activated will.
You do not have the required permissions to perform this operation with this object.
Our enviroment is a single W2k3R2 Domain with 2 Ex2k3 and 1 Ex2k7 Server.
Thx for any help!!
Kind Regards

Hi Denis,
At this time, I suggest you apply following hotfix on a problem Outlook 2007 client to check whether the error still exists:
Error message when you try to add a delegate in Outlook 2007: "The Delegates settings were not saved correctly"
http://support.microsoft.com/default.aspx?scid=kb;EN-US;950794
I would like to explain that the hotfix is included in Office 2007 Service Pack 2. Therefore, you can simple install SP2 on Outlook 2007 and create the registry key indicated in the KB article.
Please understand that before this hotfix was created, the "Send on Behalf" (PublicDelegates) permission was considered a mandatory part of adding a delegate. This hotfix lets you add the delegate without setting the "Send on Behalf" (PublicDelegates) property.
The "Send on Behalf" permission is not needed for meeting-related messages. Therefore, even without the "Send on Behalf" permission, delegates can successfully send meeting requests and responses on behalf of the calendar owner. However, when you use a delegate that does not have the "Send on Behalf" permission to send a non-meeting-related message on behalf of the owner, the operation fails.
After installing the hotfix and apply the registry key change, if the error can be resolved, we can conclude that the issue occurs due to Outlook is not able to update the PublicDelegates attribute successfully due to permission issue. After your previous post, I notice the issue occurs even if you create a new user.
At this time, would you please let me know whether the new user belongs to any group (except domain users)? I also suggest you use DSACLS tool to export the ACLs of the user object to check whether acl may reject the user to update AD attribute.
DSACLS “distinguished name of the user object” >acls.txt
Thanks,
Mike
