the error message says "Bad Request", followed by "invalid_grant"
error. If I'm not mistaken, I think I saw it too, it shows when the
application you use for connection doesn't match grants
required/requested by the evolution-ews. Did your admins follow the
instructions for the OAuth2 settings on the wiki page ? The OAuth2
login within evolution-ews links to it too.
Note there are users claiming the page is outdated , which can be,
due to the Azure web interface being changed since the wiki page was
written. I'm more than willing to update it, but I do not have a paid
account to verify what it changed to meanwhile and the developer
account requires filling a credit card, apart of other personal
information, which is something I'm not willing to give to the
Microsoft folks, I'm sorry.
