arielzusya , So how did you get this working exactly?

i made an shared mailbox named Ticket.

In OSTicket I had to rely on a local SMTP relay, which allows all mail from a specified IP to pass through without credentials, because there isn't (yet) a way to specify different mail credentials for send and receive. The rest works as described above though.

Is this solution still working for people? I'm trying right now and ripping my hair out trying to figure out what I'm missing. I have my setup identical to what you have outlined arielzusya, but unforunately an AUTHENTICATE FAIL is returned when I go to save the config. I have verified that the parent mailbox works just fine when not trying to point to the Shared Mailbox that the user has permissions to. Are there any additional settings that need to be in place on the Shared Mailbox before the authentication will work successfully? I'm also using a local SMTP relay which seems to work just fine, it's just the IMAP config that is failing, and only for the Shared Mailbox. I would love to get it working instead of having to pay for an extra full user license in Office 365

If it says authentication fail, it's either not hitting the point to where it authenticates (something is blocking this maybe?) or it is an incorrect password/username being used (Maybe the permissions are not setup properly on Office365 side?). I am not pro with Office365 and do not have an environment to test in, but that's my two cents. Wish I could be more helpful. 

No problem. Thanks for the input. It's bizarre and I haven't been able to find an answer yet. I have ensured that the base account is able to authenticate if i set it up as a separate email account within OSTicket, but when trying to access the Shared Mailbox is fails with the authentication error.I've also ensured that I can configure a standard mail client with an IMAP connection pointing to the Shared Mailbox with the exact same settings I'm putting into OSTicket with the same base account for authentication. I'm going to see if I can dig into any sort of Office365 logs to get more info other than "Authentication Failed"

@[deleted] any chance you can chime in and possible help out?

looking forward to a fix for this also. Authentication fails all the time as well / imap settings not right...working fine on Android / ios.We have around 6 mailboxes we want to use, but we arent going to buy subscriptions for office365 as well.A shame it so hard to fix shared mailboxes on osticket.are there any devs looking in to this?

Q: are there any devs looking in to this?A: Not to my knowledge.  I would hazard a guess (opinion) that since Shared Mailboxes violate HIPAA account guidelines I rather doubt that they will.
