Can't open Discovery Search Mailbox

While I was playing about with Discovery Search, I had the issue that I couldn't open up the Discovery Search Mailbox with either OWA or Outlook.

I suspected it was a permissions issue, but I was already a member of the Discovery Management group and when I looked at the Full Access Permissions in Exchange Management Console I could see that group listed.

After much scratching of my head, I decided to dive into ADSIedit and have a look at that Mailbox.

I found the Mailbox under Default Naming Context > DC=Domain,DC=Name > CN=Users, CN=DiscoverySearchMailbox{blahblahblah}

and when I took a look, I saw that the Discovery Management group wasn't listed. I just added it back in and gave it full control and the problem was solved!

Find email addresses in Exchange 2010

The quickest and easiest way to work out who (or what) is using an email address is to open up a PowerShell command window and run: 


get-recipient -results unlimited | where {$_.emailaddresses -match "address@company.com"} | select name,emailaddresses,recipienttype


for full details on the result, try 


get-recipient -results unlimited | where {$_.emailaddresses -match " address@company.com "} | fl

Backing up Ex2010 mailboxes to PST

Exchange 2010 SP1 has a new command to import and export to a PST.

First you need to give yourself permissions to do this with the following command:

New-ManagementRoleAssignment –Role “Mailbox Import Export” –User “<username>”

You will need to close down and open up the console again to gain access to the commands below.

Then you need to run the following to actually Export for a PST

New-MailboxExportRequest -Mailbox user@domain.com -FilePath \\path\to\file.pst 

If it's a backup of the archive you're after add -IsArchive on the end

You can check on the progress of the backup with:

Get-MailboxExportRequest

or

Get-MailboxExportRequestStatistics username\MailboxExport -IncludeReport | fl | Out-File c:\temp\output.txt

For full details.

You can clear any old Mailbox requests with:

Remove-MailboxExportRequest -Identity "username\MailboxExport"

or 

Get-MailboxExportRequest | Remove-MailboxExportRequest

to remove them all (and be prompted)

Very simple!

Changing the default User and Computer OU

I like to keep my "Real" Users in a separate folder away from all the other system accounts. This ensures that only valid accounts are displayed if you use LDAP lookups for various applications (e.g. a network scanner)


Windows 2003 introduced a couple of new commands that allow you to change the default location:


Users:


   ReDirUsr "OU=RealUsers,DC=domain,DC=com"


Computers:


   ReDirCmp "OU=RealComputers,DC=domain,DC=com"


You need to run this on a Domain Controller, and you need the AD to be in Windows 2003 mode as a minimum.


As you want to ensure the path to the new directory is correct, I recommend Softerra LDAP browser (it's free) which allows you to connect to the AD with LDAP and copy object locations.
