Configuring fetchmail to retrieve your mail from the Exchange servers

After Microsoft, which provides the College's email services, switched off traditional username/password authentication on its Outlook/Office365 mail servers iand changed to using solely OAUTH2-based authentication on March 29th of this year, the original documentation on configuring and using fetchmail within Imperial's email environment is no longer usable unfortunately. New documentation on getting updated versions of fetchmail that now support the XOAUTH2 protocol to work with the College's email services will be written and put up here as soon as possible.
