OWL - using more than one email from the same URL?

Has anyone found a way to get OWL to work with more than one Exchange email account? Since the URL is the same for all my accounts on Exchange (outlook.office365.com) all email accounts created via OWL in TB are overwritten by the last account added. (eg. I add email me@abc.com, then you@abc.com – the content, folders, etc for me@abc.com is identical to and comes from the you@abc.com).

I don’t use it, but have you tried the support email address here?
