I have recently had a computer issue which resulted in making a clean install of Windows 10. This, obviously, wiped everything from my computer, most of which I have managed to re-instate.

I can access both addresses without any problem on webmail and VM help confirms that everything is OK their end, but Outlook doesn't recognise the setup. They tell me that there is nothing they can do to help.
For both addresses, I get the same error. This comes up whether I use the automated process or opt to enter the details manually.
I have a screenshot of the error message:

Can anyone help me sort this out, please?
