As the school year is coming to a close, it is a good time to for everybody to clean up their e-mail box.
Delete unnecessary and space wasting messages and their attachments, if there are such.
It is good to sort messages e.g. by size, date, sender or title as this makes deletion easier.
You must clean up separately the Inbox, the Outbox and the Drafts folder.
Deleted messages are first moved to the Deleted Items folder, where messages can still be retrieved
when needed. The Deleted Items folder must be emptied separately.
