I justfound out (through your documentaion), that it is possible to import mail from an archive-folder. I already have setup my helpdesk-mailbox. Is it possible to copy mails from other mailboxes (which are requests from my customers within a different mailbox) into my new (empty) helpdesk-mailbox through the archive function AFTER I´ve setup the helpdesk mailbox in zammad?
No. The archive mode can only be triggered during adding the mailbox in question to Zammad.
It imho also only makes a differences to the moment where it finds old mail and won’t have any useful effect on new incoming mails.
Also note that email servers behave differently especially in the creation date term which may cause Zammad to not correctly detect “old” mails if you’ve moved them into another mailbox.
I moved some old mails into the archive folder of another mailbox and added this mailbox into my selfhost zammad instance.
It didn´t “find” the archive folder - neither in my already added mailbox, nor in the newly added one.
My mailboxes are hosted on my provider “AllInkl” and they already have a “archive” folder prepopulated. I added a newly folder called “archives”, which was not recognised too.
Sorry but how should I be able to answer that question? I don’t know your stack configuration.
