Scenario
Emails sent from an internal user to another internal user do not receive a signature or are not routed to Exclaimer Cloud.
Reason
Undeliverable journal reports are being sent to an internal mailbox and this has a side-effect of causing some unexpected mail routing.
Resolution
This solution applies even if message journaling is not enabled.
To resolve this issue, you need to specify a dedicated mailbox, as the recipient for Journal Report NDR messages, in Office 365 using the Windows Powershell.
To do this, you need to:
Install the Exchange Online PowerShell module
Connect to Exchange Online
Specify a dedicated mailbox
Office 365 Global Administrator credentials
To Install the Exchange Online PowerShell V2 module:
-
Open the Windows PowerShell and run this command as an Administrator:
Install-Module -Name ExchangeOnlineManagement
-
Confirm that you want to install this PowerShell module.
Note: For additional installation options, see ExchangeOnlineManagement.
To connect to Exchange Online:
- If you have Multi-Factor Authentication enabled, run this command:
Connect-ExchangeOnline -UserPrincipalName <UPN> -ShowProgress $true
In <UPN> enter your username.
- If you don't have Multi-Factor Authentication enabled, run this command:
Connect-ExchangeOnline -Credential $UserCredential -ShowProgress $true
When prompted, enter your password (and the Multi-Factor Authentication verification code if required).
