Removing Your Last Exchange Server: Part 1- Managing Recipients

Australia | Removing Your Last Exchange Server: Part 1- Managing Recipients

So my fellow Insentra crewmate, Dan Snape, has inspired you to finally get rid of your last Exchange server with his “Updates to Microsoft Exchange 2019blog article. What’s next?

With Exchange 2019 CU 12 as your current schema version, you can do so in a fully supported environment.  Once you’ve completed the commands for removing your final Exchange server, you can walk through the below actions for managing your recipients since your source of authority (SOA) is still on-premises Active Directory.

Recipient Management EMT Security Group

IIf you’ve followed the steps outlined in Microsoft’s ‘Manage recipients in Exchange Hybrid environments using Management tools’ article, you’ll note a new active directory security group was created called the “Recipient Management EMT.” Members of this group will be able to manage recipients in your organisation.

Recipient Management Commands

As a reminder, any changes made to the on-premises AD environment will be synced to Azure AD and M365 via your Azure AD Connect server.

  • To manage your synchronised recipients and groups, connect to the new management server’s PowerShell and execute the following command:
Add-PSSnapin *RecipientManagement

This will import all the required commands for managing your recipients. Run this command every time you need to manage recipients.

I have broken down the available commands into the table below with a brief description for each:

MailUser CommandsNotes
Set-MailUserUsed to set attributes onto a mail user
Get-MailUserUsed to get the results of a mail user
New-MailUserUsed to create a new mail user
Remove-MailUserUsed to remove a mail user
Disable-MailUserUsed to disable a mailbox for a mail user
Enable-MailUserUsed to enable a new mail user
  
MailContact CommandsNotes
Set-MailContactUsed to set attributes onto a mail contact
Get-MailContactUsed to get the results of a mail contact
New-MailContactUsed to create a new mail contact
Remove-MailContactUsed to remove a mail contact
Disable-MailContactUsed to disable a mail contact
Enable-MailContactUsed to enable a mail contact
  
RemoteMailboxNotes
Set-RemoteMailboxUsed to set attributes onto a remote mailbox
Get-RemoteMailboxUsed to get attributes of a remote mailbox
New-RemoteMailboxUsed to create a new remote mailbox
Remove-RemoteMailboxUsed to remove a remote mailbox
Disable-RemoteMailboxUsed to disable a remote mailbox
Enable-RemoteMailboxUsed to enable a remote mailbox
  
DistributionGroupNotes
Set-DistributionGroupUsed to set attributes of a distribution group
Get-DistributionGroupUsed to get the results of a distribution group
New-DistributionGroupUsed to create a new distribution group
Remove-DistributionGroupUsed to remove a distribution group
Disable-DistributionGroupUsed to disable a distribution group
Enable-DistributionGroupUsed to enable a distribution group
  
DistributionGroupMemberNotes
Get-DistributionGroupMemberUsed to get the members of a distribution group
Add-DistributionGroupMemberUsed to add a member to a distribution group
Remove-DistributionGroupMemberUsed to remove a member from a distribution group
Update-DistributionGroupMemberUsed to update the distribution group membership
  
EmailAddressPolicyNotes
Set-EmailAddressPolicyUsed to set an email address policy
Get-EmailAddressPolicyUsed to get the results of an email address policy
New-EmailAddressPolicyUsed to create a new email address policy
Remove-EmailAddressPolicyUsed to remove an email address policy
Update-EmailAddressPolicyUsed to update an email address policy
  
UserNotes
Set-UserUsed to set the attributes of a user
Get-UserUsed to get the results of a user

At first glance, this looks like a lot of commands and the list can look quite overwhelming (especially if you’re not comfortable with or don’t use PowerShell regularly). It may help if you look at this in a different way. Instead of seeing a long list of commands, break it down into seven categories (as demonstrated in the table above):

  • Mail users
  • Mail contacts
  • Remote mailboxes
  • Distribution groups
  • Distribution group memberships
  • Email address policies
  • Users

This brings us to the end of part 1 of Managing Recipients when Removing Your Last Exchange Server.

In part 2, “Removing Your Last Exchange Server: Part 2 – Remote Recipient Commands” we will dive into the seven categories of recipient commands.

For any questions or feedback, as always, you are welcome to contact us (we’d love to hear from you!).
