Journaling in Hybrid Scenarios

Hello techresolve!

We currently use dynamic distribution groups (DDGs) as base for JournalingRules.

The DDGs members are collected based on recipient filter which is based on AD-attributes (native or extensionattributes possible).

Furthermore, in Hybrid scenarios the DDG should be configured that it only contains UserMailboxes (not MailUsers/RemoteMailboxes), in each System (ExchangeOnpremises and ExchangeOnline).

This would also avoid duplicate journaling.

Example DDG:

Get-DynamicDistributionGroup <Name of DDG> | fl recipientfilter,name,prim*

RecipientFilter : ((((CustomAttributeXX -eq 'XXXXX') -and (RecipientType -eq 'UserMailbox')))
PrimarySmtpAddress : <MailAddress of DDG>

Example JournalingRule:

PS C:\> Get-JournalRule <Name of the JournalingRule>

Name : <Name of the JournalingRule>
Recipient : <MailAddress of DDG>
JournalEmailAddress : <Journaling Mailbox>
Scope : External
Enabled : True
