My company is planning to migrate our mail from Exchange 2007 to Office 365.  The current plan is to setup our own tenant and use ADFS and Dirsync between an on-prem Exchange 2013 environment (hybrid solution), our Windows 2008 R2 Active Directory and the Office 365 tenant space.

Can ADManager Plus create accounts/mailboxes in Office 365?  If not, what can we do to get ADM to work in this environment to create mailboxes?
