Uninstall Microsoft Exchange 2010

Published by at 10:28 pm under Exchange

Microsoft Exchange 2010 uninstall wizard throws some errors unless you previously go through the following steps.

This will remove all mailboxes, contacts, etc…! There’s no way back

We assume this is the last Exchange server. If not, be more specific on mailboxes to be removed, with -database for instance, or -server on connectors.

Remove user mailboxes but not AD user accounts!

Get-mailbox | disable-mailbox

Delete arbitration mailboxes

Get-Mailbox -Arbitration | Disable-Mailbox -Arbitration -DisableLastArbitrationMailboxAllowed

Remove offline address book

Get-OfflineAddressBook | Remove-OfflineAddressBook

Remove connectors

Get-SendConnector | Remove-SendConnector

Finally remove Public folder. This is a little bit tricky since Exchange does need one public folder database.
It can be removed with the tool ADSIEdit

Remove Exchange public folders with ADSIEdit

Run ADSIedit
Right click on Configuration and Settings…
Under “Select a well known Naming Context:” choose “Configuration”

Then browse to:

CN=Microsoft Exchange
CN=Administrative Groups
CN=Exchange Administrative Group (FYDIBOHF23SPDLT)

Now you can delete the Public Folder Database and uninstall Microsoft Exchange 2010 with no hassle.
