Email folder size

[H1uams]

My email box regularly tells me it is full. I can see the size of my email box, but how can I check the size of subfolders so I can delete on mass without cherry picking to reduce the overall mailbox size.

Webmail lacks the functionality to show a folder's storage size; instead use an email client like Thunderbird or similar to obtain this information and to manage your mailbox.
