we’re using latest stable kopano pro with outlook 2013 users with KOE. outlook is set to encrypt all outgoing mails. Quite often, outlook encrypts outgoing mails in a way, that they are not readable anymore - neither for the sender nor the receiver. We suspect, that outlook is getting from somewhere, wrong certs for recipients and then messing it up. Where are the pub certs saved in a kopano environment? If i check in webapp - i see a lot of certs present for users. Where are they stored and how made available to clients like outlook?
