You might want to post this to an Exchange group as it appears that the
migration triggered the problem. Something on Exchange may need to be
looked at.

After furious head scratching, ADP Comm asked:

| Recentl migrated to a new Exchange 2003 server and since there have
| been random issues. The most recent is individual user calendars,
| sporatically, are no longer visible or can be viewed. The user
| themself, can see their own calendar however no else that previously
| had permissions to view it, cannot. There have been no changes but
| this issue seems to just 'appear'. The individual user can reset the
| permissions however there will be no change. I am browsing through MS
| trying to find a answer, however there is still no luck. Anyone have
| any ideas?
