Microsoft says basic authentication will be disabled on Office365 in October 2020. Looking at Email::Folder::Exchange, it doesn't say if it uses basic authentication or not. I assumed it did though, and if you pry into the soap object from Email::Folder::Exchange:EWS, it seems that it does: 
use warnings;
use strict;
use Email::Folder::Exchange::EWS;
use Data::Dumper;

my $folder = Email::Folder::Exchange::EWS->new('https://outlook.office
+365.com', 'myemail@address.com', 'mysupersecurepassword');
print Dumper $folder->soap();

        '' => [
            'myemail@address.com',
            'mysupersecurepassword'
        ]
    }
},

Where can we go to see if any changes to the module are in the works? I have several instances of this module in production use and I'm hoping not to have to rewrite them too much.
