Why is my mail taking 26 GB of space when I've deleted my mail accounts?
I can't figure out why my MacBook Pro (Mid 2014) is showing that mail storage is at 26.34 GB no matter what I do. I have several Gmail accounts and 1 Yahoo account. I've delete emails, and it didn't change. Today I took all of my accounts off - I deleted them with the "-" under accounts, removing all accounts. I restarted and it STILL shows mail is taking up 26.34 GB of storage. What's going on?
