Outlook messages show as sent but are not sending

[drdavewatford]

Hi,

I'm using Outlook via the web. Regardless of which device I use (Mac, Windows) when I send a message it shows as sent in my 'Sent' folder but the recipients are not receiving my messages. The problem started today - everything was working fine yesterday.

Many thanks,

David.
