My uni e-mail uses Office 365 as e-mail provider; I've added it in Thunderbird, but I can see only unread e-mails. All the read one are not appearing in my inbox. However, if I `cat` the INBOX file, I can see the e-mails and if I mark them as unread from somewhere else I can see them. Also, adding the e-mail address on Thunderbird on Windows doesn't have the same problem. Any idea to further investgation? -- Giovanni Santini My blog: http://giovannisantini.tk My code: https://git{hub,lab}.com/ItachiSan My GPG: 2FADEBF5
