Why I can not log in to my email through my i phone

Hey sithara1234,

If you're able to otherwise browse the internet but cannot sign in, are you using a VPN? Some sites may block VPNs in various ways. You can check if one is enabled under Settings > General > VPN & Device Management. If so, try momentarily disabling it and see if you can login then.

If that is not the case or you don't use a VPN, have you been able to sign into this app previously? How about trying to access your email from Safari via your email website?

Let us know, as those details will help guide our next steps. We'll follow up from there.

Cheers!
