In the Folder Pane....'Local Folders' is an account created by default. It is usually listed at the Bottom below all your other mail accounts. But that depends - have you set up a load of pop accounts as deferred accounts so they use 'Local Folders' as their set of folders ? Have you set up 'Local Folders' as the default account in 'Account Settings' ?

Basically, I have no idea what your personal Folder Pane looks like and no idea what you mean by 'to view the folders below Local Folders'. You could have a view option which alters what you are seeing. I do not know whether you are using View > Folders > All or whether you have selected any of the other options eg: Unified

Pleae post an image of your Folder Pane and put a marker on image pointing to what you call 'folders below Local Folders'

Thank you for a list of TB's shortcuts.

All my emails are in IMAP format, not multiple POP accounts. All my TB emails initially went to my TB inbox. Also I have not setup 'Local Folders' as the default account in 'Account Settings'.

I don't know what the area "below the Local Folders" is called so I have used that description. In the uploaded image from W10 is a portion of that area. If you know what that area is called, could you please inform me?

In W10 and prior versions TB had this area. In W10, right clicking Local Folders allowed new Folders to be created and a few emails from Inbox were copied/moved to those folders. In effect, this was a way of saving those emails.

I presume that this continues in W11, but so far have not been able to find it.

I have been asking about this area since it contains many emails that have been saved and cannot be replicated.

re :All my emails are in IMAP format, not multiple POP accounts. All my TB emails initially went to my TB inbox.

The mail account above 'Local Folders' account is your imap mail account. Image shows 27 new mail in 'Inbox'. It looks like you may have a gmail account because gmail use a folder called 'All Mail'. There are a few other servers that use the gmail format. It does look a bit odd because the 'Spam' folder is missing and you have two folders that are used as 'Archive' - which is incorrect. 'Please note gmail consider the 'All Mail' as the default archive because that's where it stores all your emails.

Gmail stores every email in the 'All Mail' folder. Incoming, outgoing and archived (any email that does not have a label attached). Gmail understands that putting everything in one folder is about as useless as it gets, so they invented something called 'labels'. Labels are a type of 'tag' which is applied to the emails stored in 'All MAil'. Depending upon what 'label' has been applied, a virtual copy of that email stored in 'All Mail' can get put into the relevant 'label'. That means all incoming tend to get the 'label' called 'Inbox' or 'Spam'. It means emails can now be displayed in a manner that's more logical to the user and can be easier to organise and locate. It also means you can apply as many 'labels' as you like to any particular email and see virtual copy in various folders. In the webmail account those 'labels' look like a more conventional folder hierachy.

Thunderbird has no concept of 'labels', so in an imap account, all folders synchronise with server and download whatever is in each 'label' and it stores them in 'mbox' files that appear as Folders in the Folder Pane. Those emails that are in the imap 'Inbox' are not virtual copies. So by subscribing to see 'All MAil', it means you have downloaded everything twice. As emails on server are only stored in one location, it means if you delete anything from 'All Mail' it will get deleted from all other folders because it no longer exists. If you delete emails, they must get put into the server 'Trash' folder which in some cases may be called 'Bin'. Gmail will then auto empty the 'TRash' periodically, so in effect you never need to manually empty the Trash unless you really want to. If you choose to delete and do not put emails into Trash - you by-pass the Trash - gmail understands that instruction to mean remove label and keep in 'All Mail' as if archived.

Most people do not subscribe to see the 'All Mail' folder purely because it doubles up everything and if your Anti-Virus decided to try and fix that mbox file, you stand a good chance of losing everything in the imap account and on the server. So if you want o keep seeingit, then do make sure your anti-virus is not allowed anywhere near your profile and if you do allow scanning then never let it fix anything it finds.

It's important to see all the server folders otherwise you might miss incoming mail that has been auto directed to the server spam folder. I suggest you subscribe to see the 'Spam' folder.

re :I don't know what the area "below the Local Folders" is called so I have used that description. In the uploaded image from W10 is a portion of that area. If you know what that area is called, could you please inform me?

It's displaying all the various folders in the 'Local Folders' account. 'Trash' and 'Outbox' are default created folders. 'Outbox' is used by all accounts if you choose 'Send Later' when creating emails. All the other folders you created eg: 1931 Census

To access any of those folders you click on the folder eg: 1931 Census and it will display list of emails it contains in the 'Message List' Pane.

re : In W10, right clicking Local Folders allowed new Folders to be created and a few emails from Inbox were copied/moved to those folders. In effect, this was a way of saving those emails.

Imap account folders synchronise with server to display whatever is stored on server, so in effect they are not truelly independent copies. Getting copies of emails from an imap folder put into 'Local Folders' account means you then have a copy stored on your computer which is totally independent of the server.

The image you have uploaded was from a W10 computer. But you seem to be talking about a W11 computer.

Can I presume you talking about two entirely different computers? Are you saying you can see a load of folders in W10, but not in W11 ? Do you want to get a complete copy of what you see on W10 appearing in W11 computer ? IF yes: Have you done the following ? Obviously, you have installed Thunderbird on both computers. Are both computers running the same version of Thunderbird ? If no then get them both using same version.

Have you created a backup of the entire profile on W10 computer and moved it onto the W11 computer ?

This is how you get same Thunderbird on both computers.

W10 computer:

• Exit Thunderbird
• Access profile by doing the following.
• In windows search type: %Appdata%
• Select the '%Appdata%' file folder option - see image below as guide
• Select the 'Roaming' folder
• Copy the 'Thunderbird' folder to an external drive.

W11 computer:

• Exit Thunderbird
• Access profile by doing the following.
• In windows search type: %Appdata%
• Select the '%Appdata%' file folder option - see image below as guide
• Select the 'Roaming' folder
• Delete the 'Thunderbird' folder
• Access the backup where you have the copied 'Thunderbird' folder.
• Copy the backup 'Thunderbird' folder and paste it into the 'Roaming' folder.
• Start Thunderbird

The W11 computer should now be displaying exactly the same as the W10 computer.

If you need to create a new folder in 'Local Folders' account

• Right click on 'Local Folders' and select 'New Folder'
• Give it a suitable name
• Create as a subfolder of : Local Folders'
• Click on 'Create Folder'

If this 'New Folder' option is no longer available/greyed out or not working when selected, it is probably because you have not set up the Junk Settings for both imap account and Local Folders account. I located this issue a short while ago and reported it as a bug, but the following does fix it.

In imap account make sure you have subscribed to see the 'Spam' folder. In Folder Pane

• Right click on imap mail account name folder
• Select 'Subscribe'
• clickon 'REfresh'
• Select 'Spam'
• click on 'Subscribe'
• Click on 'OK'

• In 'Account Settings'

For the imap mail account

• Select 'Junk Settings' for imap account
• select checkbox to enable adaptive junk mail controls for this account
• Under 'Destination and Retention'
• Select 'Other' and choose 'Spam on imap mail account name'

For 'Local Folders' account

• Select 'Junk Settings'
• select checkbox to enable adaptive junk mail controls for this account
• Under 'DEstination and Retention'
• Select 'Junk' and choose 'Local Folders'

Restart Thunderbird.

Toad-Hall your answer was point on

A few of my observations are included.

I suggest you subscribe to see the 'Spam' folder.   

The download from Mozilla TB did not create a SPAM folder, but there is a TRASH folder. So are the two the same?

Are both computers running the same version of Thunderbird ? If no then get them both using same version.

I checked the versions on both W10 and W11. They are the same, except W10 is 32 bit and W11 is 64 bit. Later I will try to transfer from W10 to W11.

If you need to create a new folder in 'Local Folders' account

I tried to create in W11 a couple of folders below Local Folders. I copied emails into that folder below Local Folders. But two folders were created by TB - one above Local Folders and the other below Local Folders (see below). Both contain the emails. Is this a bug in TB on W11?

Would this transfer of folders below Local Folders from W10 to W11 also include the W10 Address Books?

re :Would this transfer of folders below Local Folders from W10 to W11 also include the W10 Address Books?

Yes. It will transfer everything you currently see and use on W10 and make it the same on W11. It will completely overwrite whatever is currently on W11. The Copy of that W10 .../Roaming/'Thunderbird' folder includes all profiles, all mail accounts,all folders, all emails, all address books, everything in calendar, all preferences. Everything.

re :The download from Mozilla TB did not create a SPAM folder, but there is a TRASH folder. So are the two the same?

No, they are not the same. If set up initially as an Imap account then all the default server folders should be auto subscribed and seen. You also should not have two folders set up for Archives.

In Thunderbird you need to get that 'Spam' folder sorted because gmail/ whatever server..do usually auto empty Trash and Spam periodically and there's nothing more annoying that missing good emails that gmail thought were spam.

In Folder Pane

• Right click on imap mail account name folder
• Select 'Subscribe' -See image below as guide - it's an older version but 'Subscribe' is still in same location.
• click on 'Refresh'
• Select 'Spam'
• click on 'Subscribe'
• Click on 'OK'

Report back on whether Spam is now showing in Folder Pane on W10 computer.

Before you transfer everything - maybe you should check a couple of things first on the W10. Can you post the following:

W10 computer:

• In Thunderbird
• Help > Troubleshooting Information
• Scroll down to 'Mail and News Accounts' section
• Copy all the data in that section and paste it into this forum question.

It means I can check that a Pop account has not been altered into an Imap account. In other words, it was initially set up as Imap from the start and is still Imap. I can also see what server you are using which helps to understand whats going on.

Then can you logon to your webmail account via a browser. I need to see the entire list of folders usually displayed on the left. Create an image file of what you see and upload image file to this forum question. This will help me understand what should be displayed in the imap account.

If you are using a gmail server then I would expect something like the image below. It's an image of my gmail webmail in 'Settings' > 'Labels' You can see all the default folders are at the top and all the 'labels' are below (they display as folders in the imap account). You can see how I have all the folders I created are selected to 'Show in Imap'

I'm wondering why you have the 'Archives' folder - I created a 'Label' called 'OldStore' where I keep archived emails because if I use 'All Mail' then they get mixed up with everything.

My linked a/c to TB is 4jpsutka@gmail.com.

The 'Mail and News Accounts' is attached.

I am not certain on how to create that image file, but I checked Settings>Labels and all were 'Show in IMAP'. But a few were not checked. Attached is a partial of my Settings>Labels.

I went through the Subscribe/Refresh and when I re-opened W10 TB, SPAM is now showing in the Folder Pane. Should I do same for W11 as SPAM is not there?

What about the double folders created in Local Folders on W11 as shown below?
