Send Message Error

I can receive E-Mails using thunderbird as a client but no send them. If I use the Microsoft web portal I can send and receive E-Mail messages.

When I send an email using any Microsoft E-Mail account I just receive the following message in a window. The Window is labeled as "Send Message Error". The message that I receive is;

Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) smtp.office365.com timed out. Try again.

I have tried the following: Changing client account settings, update software, searched the knowledge base, deleted the accounts and recreated them, removed all thundebird software and reinstalling.

What has caused this and how can I get the client the work again.

Run Windows in safe mode and see if the problem remains.

Confirm that you have smtp.office365.com on 587, STARTTLS, normal password, User Name = email address.

Timeouts can be caused by antivirus apps scanning outgoing mail. Avast/AVG with the Mail Shield are known culprits. What's the AV and its mail settings?

No. Its not the Antivirus. I just get this. Funny thing is other software that uses my E-Mail account do not work either.
