Hi !!

Yesterday we migrated over 100 users, using the same
method as earlier. We did not discover the same problem as
I mentioned below. The difference between this migration
and the others is:

Yesterday:
1. Exchange 2003 and 5.5 mailbox servers are on the same
subnet
2. Migration during day. (No datafile copy, no computer
softing)

The others:
1. Exchange 5.5 mailbox servers are placed in the users
location (several router hops)
2. When migrating mailboxes home- and commonareas are
copied to new servers
3. Computers are softed
4. Backup of Exchange servers might run during this period
