The iPhone Mail app will start not working for various reasons that can include problems with your local network, Apple server issues, and bugs with the latest iOS update. The screenshot on this page reveals iOS 8.2 with the Watch and Mail app on the same screen.
One of the most common problems with iPhone Mail will be sending and receiving email, which we have seen first hand with many complaints in regard to iPhone mail coming in, but not going out due to unforeseen issues. The solution won’t always be clear, with a fix in some situations being a soft reset or reinstalling the latest iOS update again on iPad, iPhone, or iPod touch.
We have seen polls reveal that the Apple iPhone Mail app is the most used client, although this is officially yet to be proven.
If you are seeing servers down today, or other problems, then leave a status update with detailed issues below. If there’s a major outage with iCloud or other services, this will be evident within the updates below.
