The first image - Account ijn profile - shows last files as Templates, is the 'Trash' file below the Templates or not ? It is not clear from the image whether it exists or not.

You cannot create a folder called 'Trash' because you are not using a pop account and the server already has a folder of that name.

Check: View > Folders > select 'All'

Check: Right click on imap account name in Folder Pane and select 'Settings Select 'Server Settings' click on 'Advanced' uncheck 'Show only subscribed folder' - to see if we can force it to appear. select: Allow server to override these namespaces' Click on OK

If you cannot see it.... Access the profile name folder. Exit Thunderbird. Delete these files:

• folderTree.json
• panacea.dat file
• session.json
• xulstore.json

Start Thunderbird.

Right click on imap account name in Folder Pane and select 'Subscribe' click on 'Refresh' Select 'Trash' or whatever the server folder calls that folder eg: Bin, Deleted Items etc click on 'Subscribe' click on OK.

then make sure you have selected to use that folder in the Account Settings > Server Settings select 'Move it to this folder' and select the server trash folder on account.

Please report back on results.

Hi, I didnt get a notification email about this, so unfortunately I cannot say whether this method would have worked. I did however just recreate the email account this afternoon before checking back here on my father's machine because something else had happened. So removed it, re-added, and all was well.

Likely your method would have worked if it was reseting some of that config that displayed his mailbox, but certainly the nuclear delete account and re-add worked.

Thanks Lawrence
