Hotmail emails in Thunderbird not sending

[BStacey]

I've not been able to send any hotmail emails through Thunderbird since I changed to BT. It was fine before.

Most of the time I'm getting Connection to server timeout outlook.office365.com messages too although I was getting them before I switched. Sometimes I don't get them but I'm not getting any emails through at the moment. 

My emails work on my phone on outlook for Android, just not on my laptop with Windows 10.

Thanks for reading...

Can you check you have the correct server settings

Thank you, I've just checked them and they all appear fine.

I'm using the default server:
smtp.office365.com - that's the option that's checked anyway. When I look in server settings it says it's using outlook.office365.com. So that's confusing!

Here's the message I get on timeout:
Sending of the message failed.
An error occurred while sending mail: Outgoing server (SMTP) error. The server responded: Timeout waiting for client input [LO2P123CA0030.GBRP123.PROD.OUTLOOK.COM].

Thanks again 🙂

If you are using a Microsoft Hotmail email account or as it is known now Outlook.com, you will need to use the Outlook.com server settings in Thunderbird for that account and not the BT email settings.

Thank you - I've made sure I'm using the correct settings as far as I'm aware.

Regarding this paragraph on the first link you sent me, there's no box to check for "my server requires authentication":

To protect our email server from abuse by spammers, we also require all emails sent through our email service to have SMTP authentication.

SMTP (Simple Mail Transfer Protocol) is an authentication process that identifies the origin of emails; it stops them being sent anonymously and therefore helps to combat spam
Enabling SMTP authentication is easy; you usually switch it on by ticking a box called "My server requires authentication" in your email program's settings. If you don't set up SMTP authentication, you'll get an error 530 failure message when trying to send email messages.

Ignore the link in message 2. Those setting are if you are using a BTMail email account not a Hotmail email account.

The settings you should be using are in the link in message 4.

Thank you, the settings it states are the settings I have:

IMAP server name outlook.office365.com
IMAP port 993
IMAP encryption method TLS

I've just tried sending another email after resetting the changes I made, I'm now getting this message:

Sending of the message failed.
An error occurred while sending mail: Outgoing server (SMTP) error. The server responded: * OK The Microsoft Exchange IMAP4 service is ready. [TABPADQAUAAyADYANQBDAEEAMAAxADEANwAuAEcAQgBSAFAAMgA2ADUALgBQAFIATwBEAC4ATwBVAFQATABPAE8ASwAuAEMATwBNAA==].

Did you ensure that the other settings are correct

• SMTP server name smtp-mail.outlook.com

• SMTP port 587

• SMTP encryption method STARTTLS
