Cleaning up mailboxes
When you remove a mailbox from Microsoft Exchange Server, it does not automatically hard delete the mailbox. Hard deletion may be required to free up disk space, or to remove all traces of the mailbox such that a new mailbox can be created.

The first command will set the retention period on the mailbox database to 1 minute. This doesn’t always remove the mailbox however, especially if a backup has not taken place.
The second command will cleanup the mailbox database specified, removing any mailboxes marked for deletion. The -confirm attribute will remove items regardless of their backup state or retention period.

Check the Application event log afterwards to confirm removal.
[PS] C:\Documents and Settings\waknowles>Set-MailboxDatabase "Mailbox Database" -MailboxRetention 00:00:01 [PS] C:\Documents and Settings\waknowles>Clean-MailboxDatabase "Mailbox Database" -confirm

How to configure deleted mailbox retention

Setting full administrative access on a mailbox
**When to use:** if a user needs to access another user’s mailbox; administrative access for backup/restore/support purposes
**What it does:** gives full access to the user’s mailbox to the user specified.

[PS] C:\Documents and Settings\waknowles>Add-MailboxPermission username -User waknowles -AccessRights FullAccess

Identity User AccessRights IsInherited Deny -------- ---- ------------ ----------- ---- domain.... DOMAIN\username {FullAccess} False False

Backing up a mailbox
- To backup a mailbox, give full administrative access to the user you will use to perform the backup.
- Add the mailbox to the Exchange account in Outlook
- Export the mailbox (include all subfolders) to a PST file – store in BACKUP2′s mail archive share

Restoring a mailbox
- If doing a complete restore, you will need to disable the mailbox in the Exchange Management Console. This will remove Exchange attributes from the user’s AD account.
- At this point, cleanup the mailbox database using the “Cleaning up Mailboxes” instructions
- Create a new mailbox for the user. Be sure to setup email addresses again.
- Grant full administrative access to the owner of the mailbox and an administrative user.
- Open Outlook on TS and add the mailbox to the Exchange account.
- Navigate the the root of the mailbox and go to File -> Import and Export
- Use the “Import from a file” option to import from the backup PST file. Be sure to import *all* folders. This may take a while.

Cached Outlook Contacts
Outlook caches recently used contacts in c:\documents and settings\username\application data\microsoft\outlook\outlook.nk2
If email bounces back with error messages similar to the following, rename or delete this file and restart Outlook.

USER The recipient's e-mail address was not found in the recipient's e-mail system. Microsoft Exchange will not try to redeliver this message for you. Please check the e-mail address and try resending this message, or provide the following diagnostic text to your system administrator.

Mailbox offline for single user, but working for others?
Check Application event log for error events with source MSExchangeIS (Event ID: 9646). The error detail should look something like this:
Mapi session "/o=organisation/ou=exchange administrative group (fydibohf23spdlt)/cn=recipients/cn=davidlulham" exceeded the maximum of 32 objects of type "session".

Unfortunately, the only fix for this at the moment is to __restart the MSExchangeIS service__.

Username/Password Prompt After Server Restarted
Start the Microsoft Exchange System Attendant service. This fails to start on boot, and must be started manually.
