Thunderbird: is set-up still up to date?

Hello everyone,

I have just acquired the OVH cloud version of Microsoft Exchange. Everything is running pretty smooth but I am sorry that I can't use Thunderbird at least to read and receive emails. It is not a huge loss but I have so many folders that it really helps me to check all emails in one shot..

Is there any way to properly configure Thunderbird nowadays? I have tested the walk through offered by OVH but settings don't work at all.

Cheers
