Hi all,

I am trying to migration mailboxes from exchange 2007 sp3 to zimbra 7.2 using the migration wizard for exchange.

Things are running fine, except calender items are not migrated.

Just before the migrate start, an error prompts "Could not retrieve base forder URL of Exchange Server. Appointment will not be imported.
Either the permission are not configured correctly or because of Microsoft KB article 899351."

I am runing the migration wizard on the exchange server, using the administrator account.

Parhaps the "base folder" refer to the public folder of exchange?

Any ideas?
