I tried to sign-in into my work Outlook account with aerc a while ago, from WSL2, unfortunately it didn't work with an app password[0], and OAuth2 won't cut it, because I'll have to ask the company's services administrator to grant me access.
Nevertheless, a great piece of software. Using it for personal e-mail.
