I’ve searched both here and MIIB github to see if a solution existed. Fixed a number of things this way. The mail server portion is operational and that syncs fine (so far). I can’t use Exchange server since obviously the OC/NC portion won’t update. I can do without my old data. Perfectly happy to just wipe that and start fresh. I just need to know how to go about doing this manually? Is it even possible?
The error when running mailinabox:
“Upgrades from Mail-in-a-Box prior to v0.28 (dated July 30, 2018) with Nextcloud < 13.0.6 (you have ownCloud 8 or 9) are not supported. Upgrade to Mail-in-a-Box version v0.30 first. Setup aborting.”
