Outlook client: Send error message while out of the UK

[#1]

Context:

I’m travelling. For the first time I have today used my MS Outlook client. I was In the UK on Monday Outlook worked as normal. Plusnet web mail operates normally.

Outlook setup:

In Outlook: [File][Account and Social Network Settings] [Account Settings] Plusnet

POP and IMAP Account Settings  

Outgoing mail server (SMTP): relay.plus.net

Issue:

No problem with receiving email to my Outlook folders.

I cannot send email. I have travelled abroad before and not experienced this fault.

Outlook reports, send error with message:

Task 'PlusNet_My_user_name - Sending' reported error (0x80042109) : 'Outlook cannot connect to your outgoing (SMTP) e-mail server. If you continue to receive this message, contact your server administrator or Internet service provider (ISP).'

Has anyone in the community experienced this issue when travelling?

Is there an explanation for the why, of this issue, and a fix?

Many thanks.

Edit: Apologies if I have posted this to the wrong topic.

@Auric 

the issue you encounter is because you are sending email off plusnet network, your answer is here

For off Plusnet network use you also need outgoing server authentication

Thank you for your reply. I’ve reviewed your post:

For email downloads I’m using POP3, and receive of emails is fine.

On the image you have posted the Outgoing mail server (SMTP) is relay.plus.net, (also sending email off the plusnet network), as indeed it is on my Outlook set-up.  I’m not understanding what you are suggesting I try.

TIA

@Auric 

Hopefully this might explain more, you need this

Outgoing - relay.plus.net port 587 encryption STARTTLS

Outgoing server should use authentication - same login details as the inbound server.

@Browni

Thank you for your post.

I have tried your suggestion of changing the authentication set-up for the outgoing server and I get the same result; same error message,

@Browni

A personal thank you to both. Your inputs have my email transmit up and running. 

When did this new requirement come into force; I ask as the last time I was abroad I did not experience issues.

[#8]

@Auric I find your final comment confusing - it has always been the case, even if you were off the Plusnet network when sending, as it is on all networks.

I can only speak from my experience. I did not travel in 2020 & 21. Prior to that I have been in the USA and in continental Europe. Never changed Outlook client settings till today, on advice from this community,

[#10]

Well, the requirement has existed for at least 20 years, to my knowledge, as I found out when I first tried sending from a (then) Tiscali account whilst away - in this country.

I recall many years ago encryption was not used for plusnet, force9 or free-online email clients, I  got caught out a couple of years back on my smart phone, I did not set outgoing mail to use STARTTLS and I was unable to send emails using mobile data.

I believe it still possible on network not to use any encryption.

@Dan_the_Van I don't send emails by phone - even at home, but I am talking sending through a desktop/laptop client when off the PN network.

My email is not encrypted, anyway.

[#13]

As far as Im aware , encryption is not a requirement for off network sending and never has been. Its obviously a good idea though, since you are transmitting your credentials open without it.

Nb just tried setting encryption to none using port 587 and sending with authentication  via mobile network still works

Thanks, @MisterW .
