Know More: Email Migration 

May I ask you why do you use IMAP instead of Exchange ActiveSync (EAS), please? 

It is much more better, because it will synchronize your Contact list, calendar, to do list and notes which you have in your Desktop client Microsoft Outlook via MAPI or EAS protocol (Office 365 desktop package) and in Outlook Web Access (OWA on https://outlook.office365.com).  

For Android is the best client, for Exchange, Nine e-mail client which support enforce delivery report from Exchange server (for confirm if your sent e-mail was successful delivered to target e-mail server).
