To set a forwarding address for a mailbox:

Set-Mailbox -Identity identityname -DeliverToMailboxAndForward $true -ForwardingSMTPAddress “my@mail.address

To list auto reply status for an account:

Get-MailboxAutoReplyConfiguration accountname | Format-List

To disable auto reply for an account:

Set-MailboxAutoReplyConfiguration accountname -AutoReplyState:disabled

To only restore the Inbox for a mailbox:

Restore-Mailbox -Identity restoreto -RecoveryDatabase recoverydbname -RecoveryMailbox restorefrom -Target targetfolder -IncludeFolders \Inbox

To disable a mailbox means to disconnect a mailbox from an account. It doesn’t remove either the account or the mailbox. All Exchange attributes will be removed from the account and the mailbox will be in a disabled state. Note: The mailbox does not immediatley show up in the disabled mailbox list until the Clean-MailboxDatabase process runs again. This periodically happens on the system, but can be forced with the Clean-MailboxDatabase command. To disable a mailbox:

Disable-Mailbox -Identity “Display Name

Update list of disabled mailboxes:

Clean-MailboxDatabase “Mailbox Database Name

To list all disabled mailboxes:

Get-MailboxDatabase | Get-MailboxStatistics | Where { $_.DisconnectReason -eq “Disabled” }

To connect a mailbox to a user account:

Connect-Mailbox -Database DatabaseName -Identity “Mailbox Display Name” -User accountname

Note: For the Identity or User, you can use the Legacy DN. I found this useful, when I had two of the same Display Name mailboxes disabled at the same time. You can determine the Legacy DN using the following:

Get-MailboxDatabase | Get-MailboxStatistics | Where { $_.DisconnectReason -eq “Disabled” | Select DisplayName,LegacyDN}

To check you send filter configuration:

Get-SenderFilterConfig

Note: This will override the current setting and only block the one address.
To block a user:

Set-SenderFilterConfig -BlockedSenders emailaddress

To block more than one:

Set-SenderFilterConfig -BlockedSenders emailaddress1,emailaddress2

To block an entire domain:

Set-SenderFilterConfig -BlockedDomains domainname

The BlockedSenders and BlockedDomains are “Multivalue properties”, so to add or remove entries instead of entering all them every time you just want to add one, you can do the following:

Set-SenderFilterConfig -BlockedSenders @{Add=”emailaddress1“, “emailaddress2“}

Or:

Set-SenderFilterConfig -BlockedDomains @Add={“domainname1“, “domainname2

Same idea to remove from the list:

Set-SenderFilterConfig -BlockedSenders @{Remove=”emailaddress1“, “emailaddress2“}

Or:

Set-SenderFilterConfig -BlockedDomains @Remove={“domainname1“, “domainname2
