Pmorgan25 We have read your message. We try to help you.

Hello there,can you see the maps or map that is in your trashcan? Can you put out the files?or any file?out of the map?not the map itself. Copy them to a another extern map? And delete the junkmail map that causes the problems of being stuck in the trashcan? Do not shrink or compromise the map.

Greetings Firefox volunteer.

Hello there again.

Try to locate the msf.file Locate the .msf files that correspond to the folders you want to rebuild and move them to the trash.

Make sure Mozilla Thunderbird is not running.

Open your Mozilla Thunderbird profile directory on your computer and select the desired account's data folder.

Locate the .msf files that correspond to the folders you want to rebuild and move them to the trash.

Start Thunderbird. The email client will rebuild the removed .msf index files, thus repairing your folders.

Is this possible to do?

Read this one to. The other way to find your msf.files(trash).

Thank you for your instructions but after deleting the .msf files in my Thunderbird profile folder, the junk folder did not come back.

Is it still showing in the trash folder? (a screen shot of what you are seeing would be helpful.) Is the account IMAP? (It probably is but this is important to confirm as understanding the issue correctly relies on the account type.)

Matt, it is no longer showing in the trash folder and yes it is an IMAP account. Attached is a screenshot of the subfolders under the main account.

More importantly is there a just (or similarly named) folder if you right click and select subscribe on the account name.

Who is the mail provider? (mainly is o365 involved but the who is relevant)
