uninstall Exchange 2010

This will be because of the arbitration mailboxes.

From the Exchange Management Shell run the following to get the names of the mailboxes:

Get-Mailbox -Database DATABASE_NAME - arbitration

Replace DATABASE_NAME  with the name of your database.

Then run:

Remove-Mailbox MAILBOX_NAME -Arbitration -RemoveLastArbitrationMailboxAllowed

ya i have had the same issue

just want to add to the previous comment , just make sure u have all the required roles to do the same.

as when i was doing Remove-Mailbox MAILBOX_NAME -Arbitration -RemoveLastArbitrationMailboxAllowed was not working as i did not have the appropriate role

I cannot execute these commands, I may not have the roles or the permission
Get-Mailbox -Database does not work
any solution ?
Thank you




 

Are you adding the name of the database?

yes
get-mailbox -database "Mailbox Database 1722727489" -arbitration

and the command do not work
I tried everything, very strange
Could it be a right problems?

If I format the server should I be able to reinstall Exchange 2010 ?

What do you by the command doesn't work ? What is the error?


Try

Get-mailbox -arbitration | Remove-Mailbox -Arbitration -RemoveLastArbitrationMailboxAllowed

Here the error

Get-mailbox -Arbitration
the object "-arbitration" cannot be found in 'SERVER1.DOMAIN.LOCAL'
(the issue is that SERVER1 is the AD/DC server, Exchange2010 sever is called EXCHANGE1 (member server), is it normal ?

Remove-Mailbox -Arbitration
"remove-mailbox" not a known command applet, function or executable program. Check syntax or path....

 

Problem is solved
It was indeed a permission issue
Thank you very very much
