create mailbox

Create a new mailbox

New-Mailbox -Name 'prospect NL' -Alias '' -OrganizationalUnit ' Fleet Europe/Stuttgart/Rooms and Equipment' \
  -UserPrincipalName '' -SamAccountName '' -FirstName 'prospect' -Initials  -LastName 'NL' \
  -Password 'System.Security.SecureString' -ResetPasswordOnNextLogon $false -Database 'Stuttgart Mailbox DB One'

create linked mailbox

New-Mailbox -Name 'Koroch, Ernst' -Alias 'ekoroch' -OrganizationalUnit ' Fleet Europe/Stuttgart/Users' -UserPrincipalName \

add mailbox permissions

-AccessRights <right>
where <right> may be


disable auto-mapping of

-Automapping $false

remove mailbox permissions

remove-MailboxPermission -Identity -user domari\user -AccessRights Fullaccess -inheritance all

add/remove 'Send as' permissions

Add-ADPermission -Identity 'CN=Mahnwesen,OU=Users,OU=Stuttgart,OU=ARI Fleet Europe,DC=arifleet,DC=com' -User 'DOMARI\ntrgovcevic' -ExtendedRights 'Send-as'

You can grant the permissions by using Active Directory Users & Computers. Simply open the properties of the group, switch to the Security tab, add the mailbox user or group, and then tick the Send As box and apply the change. After making this change you may notice that it does not take effect for up to 2 hours. This is due to caching on the Exchange servers. Though you can speed up the change by restarting the Information Store that is obviously not going to be practical in most production environments, so you’ll often find that you just need to wait.

Remove-ADPermission -Identity 'CN=Mahnwesen,OU=Users,OU=Stuttgart,OU=ARI Fleet Europe,DC=arifleet,DC=com' -User 'DOMARI\ntrgovcevic' -ExtendedRights 'Send-as'

Search Mailbox content

This one searches for all messages between 1/1/2017 and 12/31/2018 and creates copies of it within the Mailbox of targetmailbox into targetfolder:

Search-Mailbox -Identity <USER-ID> -SearchQuery "received>=01/01/2017 AND received<=12/31/2018" -targetmailbox "<TARGET-USER-ID>" -targetfolder "SearchResults"

set thumbnail-image

from an exchange server

Import-RecipientDataProperty -Identity dSchlenzig -Picture -FileData \
([Byte[]]$(Get-Content -path ".\thumb-DOMARI.jpg"  -Encoding Byte -ReadCount 0))

from an AD

$photo = [byte[]](Get-Content path of pic -Encoding byte)
Set-ADUser username -Replace @{thumbnailPhoto=$photo}

Import/Acivate new Certificate

Import-ExchangeCertificate -FriendlyName "webmail10102019" -PrivateKeyExportable $true -FileData ([Byte[]]$(Get-Content -Path c:\certificates\YOUR_CERTIFICATE.cer -Encoding byte -ReadCount 0))

In case of encrypted .pfx or something like that:

$pass = ConvertTo-SecureString "<PASSWORD>" -AsPlainText -Force
Import-ExchangeCertificate -FriendlyName "webmail10102019" -Password $pass -PrivateKeyExportable $true -FileData ([Byte[]]$(Get-Content -Path Webmail.pfx -Encoding byte -ReadCount 0))


Enable-ExchangeCertificate -Thumbprint 1234ae0567a72fccb75b1d0198628675333d010e -Services POP,IMAP,SMTP,IIS

DAG/Cluster stuff

Check who's master:

Get-ClusterGroup EU-DAG

Get detailed DAG info:

Get-DatabaseAvailabilityGroup STG-DAG -status | fl

Test replication health (do so on all cluster members):

Test-ReplicationHealth -server EXC02

Get mount status, copy/reply queue, Index state

Get-MailboxDatabaseCopyStatus -server exc01

Check Queues:

get-queue -server stgwpvinfexc02

Check service health (do so on all cluster members):
(test whether all the Microsoft Windows services that Exchange requires on a server have started)

Test-servicehealth –server EXC02

Test MapiConnectivity (Note: this will only test if the DB’s are mounted/active copy on the specific server):

Test-MapiConnectivity -server EXC02

Test/view replication:

Get-MailboxdatabaseCopystatus -server EXC02

Failover Cluster:

Get-ClusterNode EXC03 | Get-ClusterGroup | Move-ClusterGroup 

This will failover the 2 node cluster to the other node

Get-ClusterNode EXC03 | Get-ClusterGroup | Move-ClusterGroup -node EXC01

This will failover the cluster to the node EXC01

Move Databases:

Move-ActiveMailboxDatabase DB3 -ActivateOnServer MBX4

This example performs a switchover of the database DB3 to the Mailbox server MBX4. When the command completes, MBX4 hosts the active copy of DB3. Because the MountDialOverride parameter isn't specified, MBX4 mounts the database using a database auto mount dial setting of Lossless.

Get-MailboxDatabase stg-* | Move-ActiveMailboxDatabase -ActivateOnServer MBX4

Same as above, but moves all databases starting with 'STG-*' to MBX04

Move-ActiveMailboxDatabase DB1 -ActivateOnServer MBX3 -MountDialOverride:GoodAvailability

This example performs a switchover of the database DB1 to the Mailbox server MBX3. When the command completes, MBX3 hosts the active copy of DB1. Because the MountDialOverride parameter is specified with a value of Good Availability, MBX3 mounts the database using a database auto mount dial setting of GoodAvailability.

Outlook stuff

get all add-ins

Be aware that HKCU can only be grabbed if running in the user context!

$searchScopes = "HKCU:\SOFTWARE\Microsoft\Office\Outlook\Addins","HKLM:\SOFTWARE\Wow6432Node\Microsoft\Office\Outlook\Addins"
$searchScopes | % {Get-ChildItem -Path $_ | % {Get-ItemProperty -Path $_.PSPath} | Select-Object @{n="Name";e={Split-Path $_.PSPath -leaf}},FriendlyName,Description} | Sort-Object -Unique -Property name

Transport stuff

some stuff i used the GUI for

Relay Configuration (GUI)


Server-Configuration --> Hub Transport --> Receive Connectors (Tab)
- Select a valuable connector which matches you needs or create a new.
- for me there was 'Relay internal' which was to allow anonymous connects from spec. hosts/nets --> Double-Click
- Switch to 'Network'-Tab --> Add IP or rage to lower box.

Max connection from single IP

set-ReceiveConnector -Identity "exc03\Application_Relay" -MaxInboundConnectionPerSource 50

sets the max inbound connections per source IP to 50 (default 20)

Create an anonymous Receive Connector

after you created an receive connector by GUI you will have to run:

Get-ReceiveConnector "STGWPVINFEXC02\Application_Relay_Intern" | \
Add-ADPermission -User "NT AUTHORITY\ANONYMOUS LOGON" -ExtendedRights "Ms-Exch-SMTP-Accept-Any-Recipient"
