NoReplyAll Outlook Add-In

The Outlook Add-In can be download from this page: http://research.microsoft.com/en-us/downloads/60860f41-88ab-4bb4-8104-765feca9cfed/default.aspx

The primary function of this add-in is to add a few buttons to the Outlook ribbon to prevent people from replying to all the recipients of your message or forwarding it, etc. The add-in uses a facility built into Outlook and Exchange that is more lightweight than information-rights management but is not exposed in the existing UI. The add-in also includes a check for common email errors, such as omitting attachments or subject lines.

Allow Anonymous Relay Through Exchange Hub Transport

Use this Exchange Management Shell command to allow anonymous relay to external domains. (This should not be done on external facing servers.)

Get-ReceiveConnector "<servername>\Receive Connector Name" | Add-ADPermission -User "NT AUTHORITY\ANONYMOUS LOGON" -ExtendedRights "Ms-Exch-Accept-Headers-Routing","Ms-Exch-SMTP-Accept-Any-Sender","Ms-Exch-SMTP-Accept-Authoritative-Domain-Sender","Ms-Exch-SMTP-Submit","Ms-Exch-SMTP-Accept-Any-Recipient"

The last ExtendedRights permission is the one that can only be set through the shell.  (The other permissions can be set in the GUI console.)

Set Exchange 2010 Alias to samAccountName

Use these PowerShell commands to set a users Exchange mailbox Alias to their username (AKA samAccountName/samid):

$aliasname = Get-Mailbox -OrganizationalUnit "OUNameHere" -ResultSize Unlimited
$aliasname | Foreach-Object{
$_ | Set-mailbox -Alias $_.SamAccountName
} 

Exchange Address List Segregation

An address list is a collection of recipient and other Active Directory objects. Each address list can contain one or more types of objects (for example, users, contacts, groups, public folders, conferencing, and other resources). You can use address lists to organize recipients and resources, making it easier to find the recipients and resources you want. Address lists are updated dynamically. Therefore, when new recipients are added to your organization, they’re automatically added to the appropriate address lists.
