Force removing Exchange 2010 database – ADSIEDIT.MSC

Run Get-Mailbox -Database “Database Name” –Arbitration command to find all the arbitration mailboxes

If there are some arbitration mailboxes, move them to different databases and then delete the database again

If all above don’t work, you can use ADSIEDIT tool to delete mailbox database:

1. Open Adsiedit.msc

2. Connect to the configuration partition.

3. Expand Configuration-Services-Microsoft Exchange–Administrative Groups-Servers–Information Stores.

4. Delete the appropriate database.

I ran Set-AdServerSettings -ViewEntireForest $True then ran get-mailbox -database db1 -arbitration and all of a sudden I now see a mailbox!!! How annoying.

I moved the arbitraion mailbox to another DB and I was then able to delete the DB.

I was not aware of the Set-AdServerSettings command.

get-mailboxstatistics -database |fl


  1. Howdy this is kind of of off topic but I was wondering if blogs use WYSIWYG editors or if
    you have to manually code with HTML. I’m starting a blog soon but have
    no coding know-how so I wanted to get guidance from someone
    with experience. Any help would be greatly

  2. There isn’t anything under ‘Information Stores’, the databases are under ‘Databases’ one folder up the tree from ‘Information Stores’:

    Adsiedit.msc > Config > Services > Microsoft Exchange > First Org > Admin Groups > EAG (ExRx) > Databases

    EAG (ExRx) is a placeholder for “Exchange Administrative Group ({Ceasars Cipher of ‘Exchange12Rocks’})”
