Mail taking up 98 GB of storage but I have no mail

My mail is taking up 98 GB of data blu I have only about 30 emails in all of my folders. When I Get Info about my account, it says I am using less than 150 MB of data. Where is the 98 GB of storage being sucked from?

MacBook Air, macOS 14.6

In Finder, select Go menu > Go to Folder, enter ~/Library/Mail in the field and hit return. That will take you to the folder where Mail stores files. What are the folder sizes there? You can drill down into the hexadecimal-named folders and see individual mailboxes. You may have old accounts taking up space.

Sorry for the delay on my end. Thank you so much, that helped a lot. I found a sub folder of MailData called MFArchiveFileWrapper that had like 40 folders with the same copies of some documents I used a few years ago, but it is taking up 100.3GB. I have these same documents in a folder on my desktop/home screen, so I don’t need them here. If I get rid of all of them from here will it not affect the ones stored in the folder on my desktop?

It will not affect the files stored on your desktop. Whether or not deleting them actually frees up space will depend on your Mac's OS and drive formatting. If you're running 10.13 or later, your storage should be formatted as APFS and with that disk format, there's really only one copy of a file – duplicates are effectively just clones with pointers so if you duplicate a 10 GB file, you don't see the available space go down but conversely, if you delete 9 of the 10 copies of a 10 GB file on the drive, you don't get any space back. Older versions of MacOS used HFS+, where 10 copies of a 10 GB file would take up 100 GB of space.
