IOS10 Mail FONT Size Issues

Same thing for my company. Many of our older users are now unable to see their emails, particularly ones that originate from an Exchange environment, and thus HTML format. The update released yesterday included this: "Fixes an issue that caused some HTML email to be formatted incorrectly". However, we performed the update and the problem remains. This is really an accessibility option that has been taken away by Apple, which is just short of an assault on the visually impaired. While the option to use the larger fonts via the accessibility options does work in most areas, the one that gets the most use, EMAIL, is left behind.

Apple Support tells me to wait, and that an update should be forthcoming to correct this issue. Case ID: 100051219552

Hopefully, we will get a 10.1.1 to deal with this issue sooner rather than later.

iOS update 10.1 seems to have mostly resolved this problem. I still get a few HTML emails that appear to utilize only part of the screen both in portrait and landscape mode, but I can successfully use a two-finger zoom to fill the viewable area and when switching to landscape after zooming, landscape mode also stays zoomed in. It's a big improvement but not a complete fix.

Dude, this does not fix the problem. The iPad is Useless if I can't read the email!!!!

Please fix it ASAP. And give us the curtesy of acknoldgeing your mistake.

I am having the same problem and I have tried every fix suggested on this and other threads. When I contacted apple support, they told me that it was a problem installing the software. So I upgraded my phone to the 7 Plus - same issue. Is there any movement on this from Apple???

there is only one fix. tell everybody that emails you to send the email in text. not HTML

that's not a workable solution for work email. Apple should fix it. There was no problem with ios9

this week alone. 5 people at my Police Dept have migrated over to Samsung Galaxy because they cant read their emails. i have 4 more orders with Verizon to upgrade to a Galaxy in one other other Department, all because they cant read their emails on IOS 10

I have noticed a quirk (bug) in Dynamic Type that may explain why Braden85's suggestion is not producing the desired results. To review, these are Braden85's instructions:

Make the font even bigger

1. Go to Settings > General > Accessibility > Larger Text (or Larger Type in iOS 7).
2. Turn on Larger Accessibility Sizes (or Larger Dynamic Type in iOS 7) for bigger font options.
3. Drag the slider to select the font size you want.

Turn on other Accessibility settings

Go to Settings > General > Accessibility to make the text bold, increase the contrast, or invert the colors on your screen.

Here is the problem. If you drag the slider to adjust the size of the Dynamic Type it will have NO EFFECT unless you set it to the location shown below, or even further to the right. At least, that's the story on my iPhone 6s+. If I move the slider one "notch" further to the left than shown, the size of the font JUMPS down to a very tiny size.

So, check your settings and see if moving the slider to the position in my screen shot below succeeds in enlarging the font size to an acceptable level.

Unfortunately, that did not help me. Makes me almost miss my Windows phone!

Yes, that was it, I increased the font size as per your snapshot and the emails are an easy to read size again, thanks for curing a slightly aggitated apple mobile / cellular telephone customer
