Exchange Server 2010 Mailbox Database Move

How is the user impacted when I move the Mailbox Database in Exchange Server 2010? Will their Outlook client freeze? Will they lose connectivity to the Exchange Server during the move?

The mailbox gets locked towards the end. So I do it at night or group at a time. If you have Exch2007 SP2 and higher, it's totally online.

This issue is now resolved in 2010. No more impact.
Their mailbox gets locked at the end of the move then the user gets a message to restart outlook. The user can use the mailbox while it is moving.

So, None of my mailbox users will notice anything while my 60 GB mailbox database is moved?
Alan CoxSr. Systems Engineer | Lead Microsoft CIE Qualified FacilitatorCommented:
yes resolved in 2010 but source has to be 2007 sp2 or higher. meganuk is correct in that user can stay in mailbox.
Alan CoxSr. Systems Engineer | Lead Microsoft CIE Qualified FacilitatorCommented:
they will get locked out at the end of THIER mailbox move and give a message to restart outlook.
AmitIT ArchitectCommented:
I assume, you are asking for Mailbox move or you are moving the DB?
Mailbox and database are 2 separate things. If you are referring to a whole database that contains multiple mailboxes and you are moving the file location of this database, then that is an offline file move and the users won't be able to connect to their mailboxes while the DB moves. The users in cached mode won't notice much apart from their mailbox going 'Offline' and messages will sit in their Outbox

Good point.. we assumed mailbox move.. :)

DB move means 100% downtime. But why you want to move DB and what method you are using?
GoodDirectorNetwork & Systems AdministratorAuthor Commented:
The database is on a 100 GB C: drive with only 15 GB free. I want to move it to the D: drive that has 190 GB free. That will leave plenty of room for the database to grow over time.

I will be using the move database function in the EMC of Exchange Server 2010. It asks for the new path and then I click the move button. Fairly simple but I wanted to be sure exactly what will happen so I can properly notify my users.

So, I can safely assume that the database will go 'offline' and the users will be locked out since we don't use cached mode in Outlook?
AmitIT ArchitectCommented:
You need to notify the users as this involve a downtime.
Yep, notify users that they won't be able to access the database during the move and do yourself a favour and move it out of hours/over the weekend.

yup. 60gb should move after hours.
