Before installing any employer-related app on my phone I read the Ts&Cs. The Outlook app requires permission to do a factory wipe on the phone, and even though I was assured by the employer at the time that they'd never do that, I refused to install it on my personal phone. OK, I lose some functionality (although it turned out that I could have IMAP access to my email without any strings) but if it's important then they can provide the phone.
My device, my rules. If you want your rules then supply the device.
