• I’ve checked if the mailbox had been listed as the “JournalingReportNdrTo” in a transport rule. Is a new security feature in Exchange. If you find the email address with this configuration
then stop reading because this is the problem. Assign another mailbox for journaling reports.
Even worse the rules were not running manually.
After verify that I have two x500 email addresses in the list, I opened both and I noticed one of them has a different Active directory (AD) forest and with a different organizational unit (OU).
Once I validated both accounts, I removed the email address with a different AD information. I saved the changes and Voila!
First, check in outlook that you do not have any rule configured. If so, delete it (you can back up the rules, just in case…)
Create the rule using outlook web app. To do this, open outlook web app – in the upper-right corner click on Settings – Manage integrations.
In the left side, on Mail options go to Inbox and sweep rules.
