As of yesterday, my phone's email client will no longer work over LTE. It's very strange, I can not setup the Office365 account over LTE (I get an error telling me that the device "cant connect to the server", but as soon as I switch on my WiFi, the account sets up perfectly fine.
Continuing, if I turn off wifi after the account is set up, and try and refresh my email, I get an "Internal Error" that pops up with an option to report that seemingly does nothing. Turning wifi back on clears the issue and my phone's email works again.
I am currently using CloudMagic, which sets up and runs perfectly fine over LTE and wifi, so I don't think that the issue has anything to do with the server. I am absolutely baffled as to whats going on here and I would seriously appreciate any kind of help.
