Fun fact! If you have outlook on your phone with a work account added, chances are IT has admin access to your phone and can remotely wipe it at any time. Also means that your phone can be collected as evidence if you or the company is involved in a court case possibly related to emails
Ok I've tested this with some users that definitely do have their work emails on their private phones and I can't see what this setting is. Are you sure about this, it seems super dodgy?
If you set up intune correctly (and its a requirement) you can prevent access to the entire of m365 including outlook unless they register their device and you can use allow lists for users who are approved to use their own devices, or just block them full stop while allowing company phones access.
If yours isn't requiring registration, then its not setup to do so, you can very much enforce it, this is usually done via conditional access requiring that the device is registered before it can get access.
Often admins also forget to block web access from mobile devices, but that's also blockable via the conditional access settings (and other ways, but conditional is how I would do it). Its not perfect as its using the user agent, which can be spoofed. Personally if the client needs that level of protection then web access should just be blocked for non company devices.
You can enforce that the company is added as a device manager, that's usually how the device wipe is enforced. Access to personal data isn't really what you are granting here, it is the ability to remote wipe the entire device.
Its a proper device management system with a ton of options. You can for example force users to only use an approved list of applications on their own device for company data.
There are ways around this. I run Outlook inside of a sandbox, so you can remote wipe the sandbox, but the rest of the phone isn't accessible to anything in the sandbox even with "device admin" permissions.
There are ways around most things, but you'll have to define this sandbox on your mobile as a lot of these can be prevented with the right additional product, obviously Microsoft being Microsoft isn't going to give this away.
Yeah I'm pretty sure that's how our system sets it up, but it's supposed to be set up like that not as a workaround, I feel super duper sketchy about wiping it uses personal device. When they leave the company that's the only section of the device we wipe.
There's only like a couple of dozen uses on the account that actually use their personal devices. Mostly just the have IT staff and a few managers who need to be emergency contactable.
That's exactly why Android has this function, so they can only remotely access/wipe that profile. Everything in that profile is kept segregated from the rest of the system.
To reset a password for work. Apparently eHub doesnt work on Firefox, it has to be edge or chrome. Called the Help Center and they asked if I was using chrome and I said no Firefox. "You don't uh...have anything like chrome on your phone?"
"no, I might be able to access a work computer with chrome but I'm not putting a chromium browser on my device" (it's there because android, but all its permissions are cut off)
She just had to sit on hold while I logged on on a work computer to reset everything where if they just fucking made a webpage to work on Firefox we could have not had the conversation in the first place.
