Quota Type: bytes in the mailbox

Just now, three messages were bounced from my Thunderbird inbox. The error message given was: A message was sent to you that was returned to the sender(bounced) because it would have caused your mailbox quota to be exceeded. The following is the reason that the message was over quota: Quota Type: bytes in the mailbox Quota Available: 894.2KB Total Quota: 5000000.0KB There's very little in my Inbox, but there was a lot in trash and a bunch of sub-folders I didn't need anymore, so I deleted just about everything. The little indicator at the bottom right of the screen was still red, indicating excessive messages, so I closed Thunderbird and reopened it. The red indicator is still lit up like a Christmas tree, even though I've deleted hundreds of emails from all folders, but I resent the messages (these were between my Spectrum account and my Gmail account), and they still bounced. I then rewrote the emails, reducing the number/size of attachments, but they again bounced. Other emails from outside senders are coming through just fine. I also receive my gmail account via Thunderbird and it's behaving perfectly. It's just my Spectrum email account that's acting up, although as I said, email from outside senders are coming through without a problem. I'm doing this on my desktop, Windows 10, current Thunderbird version. I didn't go to webmail to delete any of this. I don't understand why the indicator says I'm at 99% of my quota after so many deletions. Any and all suggestions cheerfully received!!
