Do you mean your company uses InTune?
Or does it only allow Outlook?
- For InTune - the latest InTune enabled version is this:
https://www.aqua-mail.com/forum/index.php?topic=6771.0- User Agent can be changed on the account setup screen if you tap Manual
However if you also use OAUTH2 - then the server knows "who" (what app) it is talking to, not just based on user agent (which is easy to change) but also based on OAUTH2 client ID.
It's like - when you go to "my account" in Office 365 and look under "apps with access to my account" - you'll have specific apps listed, "it knows". Same thing is possible for restricting access I suppose.
More broadly speaking - if your IT Department decides to do something, they have all kinds of tools and knobs and switches on their end to enforce this, so you may or may not be able to go against their polices.
( and if you do succeed but get found out and it becomes a problem - it's entirely between you and the employer )
