For the last month or so I've been having issues with my work email account set up as Exchange on iOS 10 (iPhone 6S) not displaying the content of emails. It displays the preview but when entering a message, the content doesn't load. - It's not a connectivity issue (it happens regardless of whether I'm using 4G, home WiFi or work Wifi). - My email address does not contain an apostrophe or any symbol other than "." (I've read that this is causing issues in iOS 10). - It happens regardless of whether any or all of the threading options are switch on or off (I've read that this causes similar issues). - Other email accounts (include Exchange ones) are working fine. - There's no issue on my MacBook Pro or iMac. - Sometimes the content loads (it's working right now), but 95% of the time it doesn't. It's essential for my work to get this working! I communicate a lot by email and it's difficult not being able to reply on the go. Thanks.
