otool -arch all works, but interestingly otool -h does show all architectures for fat binaries being part of 3rd party applications (and arm64, not arm64e as system binaries). I've edited the question.

@bmike, I see, thanks. Would you mind adding this to the answer?

@bmike support.apple.com/en-us/105128 - this site says that setting up an Exchange account on your device gives the administrator the ability to wipe the device. Do you consider this as setting up a MDM?

@bmike, so if I understand correctly, for non-managed, non-MDM-enrolled devices, if you add Exchange ActiveSync account to your iOS device (Settings > Mail > Add Account), then a built-in app (default mail app) is the one that can wipe the device as it has the capability granted by default. In case you are using Outlook, then it cannot wipe the device as it doesn't have the necessary capability. Is this correct?

@nohillside You are right, but Outlook may use Exchange, right? Or am I mixing using mail service with device-wide Exchange ActiveSync service?

@nohillside You are right, I'll edit the question to make it clear I'm asking only about technical side

"4 is a personal device so no management other than what the app sends back to Microsoft" -> is the fact that the device is a personal one sufficient to state this? Some other threads suggest that Exchange can wipe your device despite it is a personal one: apple.stackexchange.com/questions/460329/… , apple.stackexchange.com/questions/344261/…

@SolarMike Why would they guess? I don't get your point, the ownership of the device should not matter, should it? What matters is if the device is a managed one and if it is enrolled in MDM. Or do you mean something else?

@SolarMike I assume 1 and 2 is an employer-owned device, while 3 and 4 may be both employer's and employee's device

@nohillside I meant the data related to private accounts stored on the device

@nohillside And in case I would have private accounts in Outlook or Teams, would he be also able to wipe the data related to these accounts?
