Be sure to ask your IT department first. Outlook/Accompli inserts itself between the user and the enterprise mail server, i.e. their cloud service fetches the mail from your work Exchange server to store and process it, meaning all your work email and your login credentials will be exposed to Microsoft. Many enterprises have policies in place prohibiting this kind of thing.
I am the IT department.
And we've already banned it. :lol:
Shame, it's a nice app otherwise.
