How can I increase my allotment for Thunderbird?

more options

I keep getting a message that I am over the Thunderbird high water mark and should delete messages. I am deleting messages from my in-box, trash, and sent messages every day. If I miss a day deleting, I am over the high water mark again. Do saved messages count in determining the high water mark? How can I increase my allotment of space? John W. Simmons

Can you provide a screen shot of the error message, or quote it verbatim? Thunderbird doesn't use any phrase such as "high water mark", so I suspect this warning comes from your email server.

Do you compact your folders after deleting messages? If not you have not deleted anything. https://support.mozilla.org/en-US/kb/compacting-folders

From: admin

Your mailbox is over the high water mark. Please delete some messages from your mailbox.

I have just compacted folders . Will see if it solves my problem.

Who is my administrator? John Simmons

Ask your email provider. Thunderbird is email client software running on your computer so that makes you the admin over that.
