In order to archive internal mails with Reddoxx Maildepot, the Exchange 2019 journal needs to be configured.
This document covers the premium journaling with pop3 (this requires Exchange Server Enterprise CALs).
It is also possible, but not described here, to use database journaling which does not require additional CALs.
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”.
For now, only PlainTextAuthentication can be used, so we need to change the Login Type by using the Exchange Management Shell.
Use following Commands:
Set-PopSettings -LoginType 1 Restart-Service MSExchangePOP3; Restart-Service MSExchangePOP3BE
Keep in Mind, that when configuring the POP3 Connector, the Security needs to be set to "None"
AD Adjustments to Journal User
Set the Journal User Account Password settings in the Active Directory to never expire.
