We had a user quit recently.  Three days ago I copied his entire Maildir folder

to that user's Maildir/.JoesEmail.  I changed ownership and made the permission

didn't work to show
the new folder.  Today, in his Thunderbird client, I subscribed to the 
'JoesEmail' folder.  I
restarted dovecot and restarted Thunderbird.

In Thunderbird, the 'JoesEmail' folder now shows, but it is empty and shows 
none of the
subordinate mail folders.  I ran 'doveadm index -u newowner JoesEmail' and
'doveadm force-resync -u newowner JoesEmail'.  This didn't help.

I did this once before with a previous user who quit and only changed 
ownership, no
subscribing, no doveadm, and that worked.

What am I doing wrong?

Your description might be interpreted one way or another, esp. "copied his
entire Maildir folder ... to that user's Maildir/.JoesEmail".

Also, it depends on how you have configured mail_location.

If this means that you have:
Maildir/.JoesEmail/{new,cur,tmp}
Maildir/.JoesEmail/.mailbox/{new,cur,tmp}
Maildir/.JoesEmail/.mailbox.submailbox/{new,cur,tmp}
now, that will clash with the standard Maildir format:
https://wiki2.dovecot.org/MailboxFormat/Maildir

You would need to move the subfolders with a leading dot of .JoesEmail
into:
Maildir/.JoesEmail/{new,cur,tmp}
Maildir/.JoesEmail.mailbox/{new,cur,tmp}
Maildir/.JoesEmail.mailbox.submailbox/{new,cur,tmp}

If you use :LAYOUT=fs to mail_location, .JoesEmail should spell JoesEmail

Subscription is needed only, if the mail client "displays subscribed
folders only" or does not "display all folders". The meaning of the
setting varies from client to client.

Another way would to keep the other account and share it via ACLs:

Steffen, thanks for your reply. I did have the copied folders as shown in your 
first example. I
changed that to what you show as the remedy. The target user's Maildir folder 
now has:

drwx------  5 mpress domusers   4096 2017-06-28 20:07 .Deleted\ Messages.Junk/
drwx------  5 mpress domusers   4096 2018-07-16 23:22 .Delta\ Dental/
drwx------ 21 mpress domusers   4096 2018-07-17 16:48 .Dennis\ Email/
drwx------  5 mpress domusers   4096 2018-07-16 23:15 .Dennis\ Email.Deleted\ 
Items/
drwx------  5 mpress domusers   4096 2018-07-16 23:15 .Dennis\ Email.Deleted\ 
Items.Sent/
drwx------  5 mpress domusers   4096 2018-07-17 17:02 .Drafts/
drwx------  5 mpress domusers   4096 2018-07-17 16:35 .ESI/

Where '.Dennis Email' is the folder for the old user. I copied the old user's 
'Maildir/.Deleted Items'
and 'Maildir/.Deleted Items/Sent' to the target user's 'Maildir/.Dennis 
Email.Deleted Items'
and 'Maildir/.Deleted Items/Sent, respective. That how I understood what you 
advised. There are
more such subfolders, but I thought I'd try this one first.

However, still only the "Dennis Email" folder shows in the mail client, empty, 
no sub-folders
even though "Deleted Items.Sent/cur" has plenty of mail files (1522).

I did try running 'doveadm index -u mpress "Dennis Email"', again; and 
restarting dovecot and
thunderbird again, but still nothing.

First check if Dovecot thinks the folders are there:

doveadm mailbox list -u "mpress" | grep Dennis

yes:

# doveadm mailbox list -u "mpress" | grep Dennis
Dennis Email
Dennis Email.Deleted Items
Dennis Email.Deleted Items.Sent

That means: Dovecot sees them, but your client is not.
Are you absolutely sure the client is set to "display all folders"?
Secondly, make sure Thunderbird rescans the folders. Sometimes you need to collapse *certain* levels and expand them. I mean, collaps the whole tree of the account, then expand it again, see if the triangle in front of Dennis Email appeared, tap there, a.s.o. I have a Thunderbird client, that for whatever reason I don't know, "forgets" about a certain hierarchie (subtree) now and then.

As another test, you could speak IMAP:

telnet localhost 143
1 login mpress "pwd"
2 list * *
3 lsub * *

You could manually add those to the subscription file, if LSUB does not display the folders. LSUB displays only subscribed folders, LIST displays all.


Then make sure that each of the three folders contain the cur, new, tmp
subfolders.

They do:

drwx------ 2 mpress domusers 4096 2018-07-13 14:30 ./.Dennis\ Email/cur/
drwx------ 2 mpress domusers 4096 2018-07-13 14:30 ./.Dennis\ Email/new/
drwx------ 2 mpress domusers 4096 2018-07-13 14:30 ./.Dennis\ Email/tmp/
drwx------ 2 mpress domusers 2678784 2017-06-23 12:14 ./.Dennis\ Email.Deleted\ 
Items/cur/
drwx------ 2 mpress domusers 180224 2016-06-20 16:29 ./.Dennis\ Email.Deleted\ 
Items/new/
drwx------ 2 mpress domusers 16384 2016-06-20 16:29 ./.Dennis\ Email.Deleted\ 
Items/tmp/
drwx------ 2 mpress domusers 507904 2018-07-13 13:02 ./.Dennis\ Email.Deleted\ 
Items.Sent/cur/
drwx------ 2 mpress domusers 4096 2015-02-23 17:51 ./.Dennis\ Email.Deleted\ 
Items.Sent/new/
drwx------ 2 mpress domusers 4096 2018-07-13 13:02 ./.Dennis\ Email.Deleted\ 
Items.Sent/tmp/

Does the Dovecot log contains something?

Nothing at all when searching for "Dennis Email"
