This is a nagging issue for me. I have no viruses and I keep my box compacted but I am constantly receiving a popup saying that the message may have a virus or the box may be full. If I choose to skip the message, my emails get scrambled and the contents of the message do not match the subject or sender so I have say no and keep checking the Get Messages button. This is really annoying when I get over 100 messages a day. Am I alone here or is there a solution already in place to fix this issue?

Which mail protocol is this account set up to use, POP3 or IMAP? You can check by clicking on the account name in the left pane, then View settings for this account (right pane) | Server settings (left pane) | Server type will be shown at top of right pane.

I have quite a few accounts but the main one is POP3 which is the one that is having this issue.

First, backup your Profile ( )

Create a new sub-folder under Local Folders. Move all of the messages currently in your Inbox to that new subfolder.

Confirm that you have made the recommended backup of your Profile.

Close Thunderbird and navigate to the \Mail sub-folder of your Profile folder. Delete both the file Inbox.msf and the file Inbox with no extension.

Restart Thunderbird and you should find a new, empty Inbox folder in place. Copy any messages you MUST have in your Inbox from the sub-folder created above to the Inbox. Compact the Inbox after those messages are copied in.

The "Real Fix" entry in this article -- also describes this process.
