Outlook was an absolute mess on my last android phone it didn't work at all.
I moved to thunderbird on my PC and like that because it is independent of Office and means I can maintain an email client on my PC without shelling out £££ for that.
I maintain the same client on android and as I said it works sufficiently. But the consistency of the download process is a bit flakey and the notifications do not work despite them being turned on (I do know how to do this). This is a common occurence on android where you find on one app or another the notifications simply won't work or come through in a timely manner.
Investigations on the net seem to imply its the basic android tools that the email clients use that could use some improvement.
I never had any such experiences using Apple, which just works straight out of the box.
I think it is worth adding that when you get an apple, that is pretty much it you are running apple.
When you are running Android you are running say Samsung UI on top of Android, or Nokia UI on top of Android etc. This makes the probablity that there will be some clashes/bugs in the way different phones running android will work, ie not all android phones are equal.
I switched to Samsung from Noika because a) I needed esim and b) samsung offer great support (I think 5 or 6 years) which a lot of budget manufacturers like Nokia don't.
So far I think the Samsung is better/less bugs at running Android than Nokia. I guess this is because they sell more phones, and probably have a bigger team on the UI programming.
