We have the com.apple.calendarserver user configured in the Calendar preferences, but when the outbound invitation mail is sent, the log reports authentication issues. There is a mismatch between the password configured for the com.apple.calendarserver system user, and that entered in the Server.app preferences.

The other is labeled “icalserver.invitations” and it stores the password for whatever IMAP/SMTP account(s) you are using.  Normally that account is also com.apple.calendarserver, but it may be different if the admin has chosen to use an external mail service.

It would be up to you to then copy that into the Edit invitation settings.
