Configuring preferences and options in Outlook.com
Mine said that I was using 11.7GB out of 15GB and 5.6GB of the 5GB - they shut off my email - could not send or receive. I deleted a bunch of old stuff with attachments and got down to 4.1GB out of 5GB and am again sending and receiving email, but what a PITA! Have had this account for over 26 years and am looking to change.
