Cannot verify server after using VPN
Hello
following update of iPhone (14.3) I am receiving an error "Cannot verify server" from the mail app after using a VPN connection, the error relates to all my email accounts using MS365, outlook.com and an on-premise exchange server.
The only way I'm able to get email working is to close the mail app then force restart the device.
Work colleagues are also reporting the same issue on their iPhones and iPads so it is not a device issue.
Do you know how to resolve this issue?
Regards
Kevin
