[rt-users] RT with Office 365 Outlook

[Donny Brooks]

We recently migrated from in house Postfix to hosted Office365 Outlook/exchange. I have been trying to figure out how to get RT to work with this setup but the only way I can see to do this is to "burn" a license or 4. With each one costing us around $20/month I would rather not do this. Has anyone successfully gotten RT to work with O365 without multiple email accounts? I was wondering if it could be done with "shared mailboxes" since I found the following instructions on accessing a shared mailbox via IMAP:
 
 
Exchange Configuration:
  USER EMAIL: user at maindomain.com
  PASSWORD: password

  SHARED MAILBOX: shared at anotherdomain.com      (could also be @domain.com, of course)
  SHARED MAILBOX ALIAS: shared-mailbox
  Note: Please make sure to create the UNIQUE alias always with the mailbox, because it creates the user [alias]@maindomain.com. In this case shared-mailbox at maindomain.com
 
Settings for IMAP Configuration:
  EMAIL ADDRESS: shared at anotherdomain.com (shared mailbox)
  IMAP SERVER: outlook.office365.com
  SMTP SERVER: smtp.office365.com
  USERNAME: user at maindomain.com\shared-mailbox  (user\shared mailbox alias)
  PASSWORD: password (user's password)
SMTP LOGIN IS DIFFERENT (!)
  USERNAME: user at maindomain.com  (users email)
  PASSWORD: password (user's password) 
 
It has been a long time since I have delved into the bowels of RT. It has been that rock solid for us. So any and all help is much appreciated.
