How to access office email with a rooted device?

My office is moving towards device management, so if a device is rooted, it can't connect and access my office emails, calendar and contacts.

Question, can I have stock and custom Rom, with stock not rooted and custom Rom rooted?

Alternatively, have custom Rom and undo root.

In the worst case, I can forget about accessing my office exchange but all my contacts are on it, so I need to keep double copies of contacts in office exchange and gmail, which is really a pain. Thanks.

If anyone know a solution to this, please drop me an answer. Thanks.
