Davmail not authenticating request to exchange

[halvabner]

I am provided with firstname.lastname@student.university-name.edu.country-tld as my address. I can access the mailbox associated with that address as provided by my university at https://mail.university-name.edu.country-tld. It prompts me to log in with the credentials of the form:

firstname.lastname
password

like so:

then I am greeted with

this is what I see when I log out

I have been told that I can connect to it with Davmail. I launch Davmail with the following configuration:

I then start Thunderbird and configure it as follows:


I get the following messages in the logs:


Furthermore, after decrypting traffic between Davmail and the exchange, I find this:

I can do GET /EWS/Exchange.asmx from my browser but it prompts me with a basic HTTP auth, which after I feed my credentials, redirects me to this thing that looks like an XML

Davmail instead receives 401 Unauthorized because it doesn't authenticate with the credentials I typed in Thunderbird.
How can I make Davmail use my username and password in the HTTP requests to the exchange? Is there something wrong with the way I'm using it?
Thank you in advance

Why is there no feedback at all, did I say something wrong 😭

@halvabner : In your Thunderbird configuration, have you tried specifying firstname.lastname@student.university-name.edu.country-tld for the username instead of firstname.lastname? I know firstname.lastname doesn't work with my DavMail/O365 setup and IMAP client.

Also, I'm not sure about davmail.mode=EWS, but I don't think the currently released version of DavMail supports a davmail.url property setting that looks like *.country-tld for davmail.mode=O365Manual or O365Interactive. The next version should though as changes for this have already been committed to the code repository.
