I think it could be related to the Exchange LegacyDN attribute. This
attribute changes when the user is migrated from 5.5 to 2000/2003 if I
am not mistaken. In 5.5 the legacy attribute is based on the Site name,
where as in 2000, the attribute is just based on the First
Administrative Group name. I am sure if you add the User again to the
permissions list of the calendar with Owner privileges they can modify
the calendar.

Subject: [exchangelist] Mailbox Migration issues for modifying old
calendar entries

Hi hope someone can assist    
    I am migrating users from Exchange 5.5 to Exchange 2003 cross site
using exmerge in batch mode. However, I have come across a problem with
calendar entries that were created before the migration of a user took
If a user is on 5.5 and makes creates an appointment in a calendar and
then that user is migrated from 5.5 to 2003, then when that user tries
to amend the entry they are denied access. Looking at the permissions on
the calendar folder for the mailbox where the appointment was placed
which is still on 5.5 then the explicit permission settings of the users
migrated show up as X500 addresses. Adding an X500 address to the
migrated users proxy addresses makes no difference. What I have found
that I need to do is change the default permission to Owner to allow
this to work. 
This is not a good solution and I would like some thoughts on a better
