After migrating with the Calendar Synchronization agent you cannot assign "Delegate" rights within Outlook for other users.
When using the "Calendar agent" before using "Mail Target Agent" a property is not written for the new Mailbox.
In other words, if the Calendar agent is creating mailboxes the property is missing. If the Mail Target agent creates
the mailbox, the property exists.
The property that does not exist in the "Root" of the information store is called "PR_IPM_APPOINTMENT_ENTRYID."
At this time there are several potential workarounds which will fix the issue.
1. Logon to the profile effected with Outlook 2007 (potentially higher versions) which will check and repair the profile with the missing entry.
2. Run the script provided below - which populates the missing property and repairs the profile. (Please note the reporting doesn't reveal or reflect what is done so you should ignore the generated report at this time. )
The script comes with a readme.htm which was not exactly designed for this issue. The only thing that needs to be changed in the script however is denoted in this line.
"Open the RebuildContainerClass.vbs script file with any text-editor and modify it to run on the target Exchange server in full mode, by setting the mapiReportMode value to false (mapiReportMode = False). "
3. Recommend or run the MTA first (to create the mailbox) , then the CSA can be used and it will prevents the issue. Note: Running MTA second, after CSA, will leave the issue of the missing property. The MTA will not detect or populate the property.
Copy the LEDN file and the script to the same directory and run it from there with the shortest path possible for convenience. This can be done on the QMM console and under and account that has permission to access the Exhange mailbox. The service account used for your target Exchange typically.
Example,
c:\cscript.exe "c:\myDirectory\RebuildContainerClass.vbs" [servername] [filename] [domainname\username] [password]
Replace the bracketed variables with the correct information.
