Can get email on WiFi but not 3/4G

[Jaco45er]

Hi there

I have an iphone SE, I can use email on WiFi, but as soon as I am on 3G/4G, it fails with "Cannot Connect to Server for".

It was working but without anything changing it's stopped. 

Any ideas of things to try would be appreciated.

Thanks

Hi @Jaco45er How strange! Are any other apps or webpages you're unable to access?

Hi Jack. Everything else is fine. I even have 2 other email accounts on the phone that work, it's just this main email that won't work unless on WiFi.

I was wondering if it was some sort of security/spam setting on my account ?

It sounds like it could be a security issue with your email provider, or within the device itself. I've done a bit of digging and like looks like a fairly common issue with Iphones. Please could you give the fix mentioned here a go and let me know how you get on?

Hi Jack

I followed the examples, deleted the account and re-entered all the parameters for that account and now its working.

Many thanks for your help Jack
