I upgraded to the new 45.0 version of Thunderbird; however, ExQuilla for Microsoft Exchange is no longer compatible with Thunderbird 45.0.

This means I have lost my inbox completely - it disappeared.

I have been trying to add this email account again as an existing account; however, it can't recognise it.

What can I do to fix this?

How did you determine that? ExQuilla is supposed to work with Thunderbird 45. https://addons.mozilla.org/en-US/thunderbird/addon/exquilla-exchange-web-services/
