Hi Experts, (Server 2008 R2 SP1)

To say I am having major problems with my current install of Exchange 2010 SP1 is an understatement.  The install of Exchange worked fine (except for a problem I had getting the mailbox role installed, but this was solved quickly).  I have yet been able to access access exchange either by EMC or EMS and I have tried everything to get this working.  To date, I am exactly were I was three weeks ago and am starting to pull my hair out.  Now all I want to do is to remove exchange 2010 altogether and start again but of course even this isn't going to plan.  When trying to remove the mailbox role, I get this error:

"Uninstall cannot continue.  Database Mailbox Database 0036967436' This mailbox database contains one or more mailboxes, mailbox plans, archive mailboxes, or arbitration mailboxes"

 

"Uninstall cannot continue.  Database Public folder database 0747642716 is the default public folder database for the following mailbox databases 0036967436.  Before deleting the public folder database, assign a new default public folder database to the mailbox databases.


I have no users etc on this server at all (they are all currently using the existing Exchange 2003 box), so I want to remove this exchange 2010 install without effecting the exchange 2003 live box.


I am also getting an error with regarding the connector between exchange 2003 and 2010 but i'm assuming this is just a matter of deleting the connector?

Please please please help!

Just delete the databases manually. First the mailbox database, then the PF database. Then uninstall.

The relevant commands are REMOVE-MAILBOXDATABASECOPY (if there is a DAG) and REMOVE-MAILBOXDATABASE.

In the meantime, you may benefit from this:

sorry for my lack of knowledge but these commands should not have any effect on my existing windows 2003 Exchange

Each command requires you to specify the relevant database name. So, it would look something like:
REMOVE-MAILBOXDATABASE "Mailbox Database 9983247" and therefore only apply to that specific database.  in other words, it will not have any effect on any other aspects of your infrastructure.

Now I am getting this error:

term 'Remove-mailboxdatabase' is not recognized as the name of a cmdlet, function, script file, or operable program.

I am running this command within EMC

you will need to delete the arbitration mailboxes before deleting.
