In order to archive internal mails with REDDOXX Maildepot, the Exchange 2016 journal needs to be configured.
This document covers the premium journaling with pop3 (this requires Exchange Server Enterprise CALs).
The alternative (that not requires CALs) via database journaling is of course also possible.
After creating the journaling mailbox, simply select the relevant database(s) in ECP => Server => Databases and select the journaling mailbox in the Maintenance area.
The following steps are required for configuration:
Create Journal mailbox
Create Journal group and select users
A Journal group is needed, because internal mails only for specific users shall be covered with journaling.
If this would be done without a journal group, the new healthcheck mailboxes would also be archived with the REDDOXX Maildepot.
Create and configure Journal rule
Activate POP3 Service
The services “Microsoft Exchange POP3” and “Microsoft Exchange POP3 Backend” services need to be activated in the Service snap-in.
It is recommended to use “Automatic (Delayed start)” as autostart method, as sometimes the services would not start correctly after a reboot when only set to “Automatic”.
AD Adjustments to Journal User
Set the Journal User Account Password settings in the Active Directory to never expire.
