If it isn't in the Trash folder, it's likely gone.

The IN folder really brings together the inbox of several email accounts under one roof. I still have all my email accounts and their respective inboxes. At the moment I am having to check all the accounts individually.

What I was hoping is an explanation of what I would have to do to reconstruct the IN folder so I would have only one place to check all the aggregated inbox mail received. Isn't this one of the reasons to have an application like Thunderbird?

Surely there is a way!

Your reference to the IN folder confused me. And I"ve never seen the unified inbox in Local Folders. Try this:

1. click view>folders and tick unified folders
2. once that appears, rightclick, select properties and then click the 'choose' button
3. from there, tick the inbox for each account to be added to the unified view

Let me know if that resolves the issue.

rightclick on what?

I got unified folders appearing below my list of folders and accounts but nothing happens if I rightclick on it. Basically it looks like a copy of all that I already have but under a "Unified Folders" header.

Sorry. I meant to rightclick on Unified Folders after highlighting it. The option 'properties' should appear. If not, can you post a screenshot of what you see?

Menu Bar Customize

I thought there was a way to unify the IN folder from accounts settings

No. the unified folder is a virtual folder and there are no account settings to do it. You should see 'Inbox' in left side folder pane. Rightclick on it. this is the folder you set up by clicking view>folders>unified folder. The folder pane should have the words 'Unified Folder' with Input directly below it.

If I right click on the Inbox under "unified folders" I get a menu as shown in the attached screenshot.

That's right. See the entry 'properties' there that I referenced in earlier instructions? click it and then click the 'choose' button

Properties: see photo.

What do I do with this??

Ok, your earlier deletion is causing problems. Try removing it from view>folders menu, shut down thunderbird, in profile folder, look in the Mail folder for a possible folder named 'smart mailboxes.' if present delete it. Then, restart thunderbird and reactivate the unified folder and try again with rightclick and selecting properties. We'll get through this.

Now I'm seeing a lot of mail in that Inbox (unified folders). Rightclick > properties shows a different window.

I note that the Inbox and Sent both carry emails from different accounts I have and I assume that messages from all accounts will appear likewise.

You have indeed helped solve the issue - not quite as I expected but it does the job I require.

Mission accomplished.

So perfect! Wonderful and Great!

Thank you

I was glad to assist. However, do you have 13 accounts? If not, my guess is you ticked the accounts, and not their folders. So, if you have fewer than 13 accounts, rightclick again there and on the 'choose' button, expand each account. Untick the account itself and just tick the inbox. when done, you will also see a unified Sent folder and a unified trash folder. For each, rightclick, select properties, and then choose.

Yes. I do (almost). I have 12 email addresses but it is not so much for the addresses themselves but more as a way of providing a different address / identity when it becomes convenient or necessary to do so.

Consequently, I would have to keep track of any messages received on these addresses and act accordingly.

What I find strange is that the Sent folder has 12 ticks (Sent of each account) but still shows up as 13. Nothing else is checked as far as I can see, including the "Local Folder". (Is this Local folder necessary?)

There seems to be a bug. I see that the sent folder has the Local folder included in spite of it not being selected. The local folder itself does not show the said folder yet trying to move it, it states it's already there.... but it does not show up in the Local Folder list. (this refers to what I see under "Unified Folders")

If there is a sent folder in Local Folders, Thunderbird somehow is including it. If no account is related to that folder you may be able to just delete it.

Better if I leave it there. Better not do something which I cannot reverse!
