Mail account shows up in Account Settings, but not Sidebar after setting Global Inbox
Multiple Catch-22's here. I tried to change all of my accounts to a Global Inbox. I thought that I had moved all the mail from my Verizon inbox before I changed it to go to Global, but some of the sub-folders did not transfer either to the Global Inbox or the Email Backup folder that I created. Now the Verizon account does not show up on the start page sidebar, although it does show up on the Account Settings popup. It's in the Preferences file (I think - instructions were for Window7/Vista and I'm running Win8). Mail sent to the Verizon mailbox is now properly stored in the Global Inbox (twice!) and I had archived all the 2014 and earlier mail, so all that I can't find is about half my 2014 Verizon messages. A test message sent to the new Comcast inbox shows up in BOTH Local Inbox and the Comcast Inbox. Since I can't see the Verizon account on the main screen, I can't right-click on it and select Repair Inbox, as recommended elsewhere. Since it already exists on Account Settings, I can't just recreate the account. Any ideas on how to Find the Phantom Verizon Account will be greatly appreciated.

The mail files from your Verizon account still exist in your profile folder.

Use this add-on and import the messages from the Verizon mail files to the current location underneath Local Folders.

Thanks, christ1. I found some of the files, including some in the subfolders that I thought I had archived and deleted. But I have a feeling that there are still some 2014 messages missing. I still don't see the Verizon account listed. Thanks for what I was able to restore.
Your not going to see the verizon account listed anywhere but in account settings as it not has no folders. You will however find a folder on your hard disk in your profile folder.
Go to Help menu (alt+H) and select troubleshooting information Click on the show folder button. open the mail folder in the windows explorer program that opened. Now open the one named for your Verizon server. In that folder you will see files named for example inbox and inbox.msf. The files with no file extensions are your mail. with filenames matching their original folder name in Thunderbird. There will be sub folders for each sub folder you have in Thunderbird with the respective name and an sdb extension. open those sdb folders to access the mail in those sub folders.
Now you have exact on disk locations for the mail, use the import export tools Chist1 mentioned to point to those locations to import mail.
