As already stated, I have never had a problem with email abroad.
I never use webmail and use Outlook 2010 on a laptop and Blue Mail on my phone, I never use a VPN for either.
I use both hotel WiFi and mobile 4G when abroad.
Obviously of no consolation for those experiencing problems but just to prove the nonsense that BT spout regarding mail clients.
I don't think it's nonsense what BT are saying about mail clients, though it would be good if there was an official and detailed statement on using email abroad.
I never use a VPN and my mail clients have worked fine abroad UNTI,L for some reason, logging in again is required.
Fortunately for me, the web mail on Edge browser (Android) has so far worked as my backup option.
Can you clarify what you mean by 'logging in again'.
Mail clients (unlike webmail) don't stay logged in to a mail server. They login, fetch mail and then logout at whatever interval you have set for fetching mail.
On my Windows 11 Pro PC and MacBook Pro, I use eM Client as my email application.
On my iPhone and iPad, I use AirMail and occasionally Apple's Mail app.
Without any further configuration changes, my PC is now sending emails successfully - I did nothing but simply tested it again just now and it works again so my setup of the server settings was clearly correct but something was amiss at BT's end I guess.
I have also just set up my email account from scratch on my iPhone and iPad in AirMail and both work now too. I did this exact same thing two days ago and it failed.
I have no clue as to what's going on.
I suspect s/he means having to re-configure the email app's server settings with the new password when BT forced a password change on them.
By logging in, I mean when a client asks for the password again as a security check. Those would normally only happen on very rare occasions in normal UK usage. With Outlook for Android you only need to supply your email address and password and it sets up the account for you. That's usually it, but on some random occasions it will al6l you to provide the password again.
