I cannot attach documents to e-mails any more because I have exceeded my file storage limit. This happened because I removed a user and thus reduced the limit. In fact I am well past the limit now. How do I delete my previous e-mail attachments on mass so I can carry on using e-mail?
I have looked at previous answers to this and it looks like you will expect me to go through all my old e-mails and delete each one separately. I don't have time to do that, surely there is a way to delete them all at once.
