This switch will be flipped at the beginning of October this year, giving users plenty of time to adapt to the changes. This does not mean that devices with iOS 13 installed will be unable to use Microsoft Teams, it just means that Microsoft Teams won’t be able to update itself. This means that security updates won’t support iOS 13, which can be a pretty big omission when considering Microsoft Teams. However, if something is stopping you from updating your phone, don’t be too worried. If you already have Microsoft Teams installed on your current phone, it’s not like the app or your data within will be deleted after October. It just means that any new changes that Microsoft introduces will be incompatible with your phone, and won’t be installed. A message in the Microsoft 365 Admin Center states: However, if your phone isn’t updated, and there’s nothing stopping you from doing so, it’s a good idea to get on it sooner rather than later. A lot of Microsoft Teams updates are security-focused, and if you’re missing out on these, your business’s integrity could be at risk. It can be frustrating to feel like you’re left in the dark if you’re using an older operating system, but companies do have to make a cutting point when accommodating an operating system becomes more trouble than it’s worth, and a 90% user base using iOS 14 is a fairly reasonable point to make that decision.
