I’ve got this idea when I was staring at one error message that was generated Office 365 for a user who was trying to send email message to another user who has a full mailbox… The guy who sent me this error looking for help, did not even bother to read few lines in the email that could explain all the problem for him!

So I thought OK, I got an idea that is going to do a great good for everyone! I’ll start from now on to document every single error message that I get. The only condition that I’ll follow is it must be related to Email. Be it Office 365, G Suite’s Gmail, or Microsoft Exchange Server.
