Downgrading to IOS 10.3.3

[Drewmich]

I have been running my Iphone 7+ at 10.3.3 and refusing to upgrade to 11 as I knwo the Outlook IOS APP sucks under ISO 11.X

I just had to restore my Iphoen 7+ and it forced me to update to IOS 11.3.1. Once the restore was completed - my Outlook IOS app was updated and it sucks. Very few settings and I hate its interface compared to Outlook IOS under 10.3.3

I am trying to "downgrade" to 10.3.3 but realize I need the 10.3.3 IPSW file that is SIGNED or the restore process won't allow me to use it?

Anyone know the tricks on how to do this downgrade safely ...

OR - better yet - how to fix the Outlook IOS app to run like it did in 10.3.3??

Thanks!

It’s not possible to revert to a software not signed by Apple, even if you’ve saved the ipsw file.

Contact the app developer (Microsoft, in this case). They are the only ones able to help. If there are enough users, they might even add some features again that you’ve liked before the update.
