Can you please try

doveadm exec imap -u username_of_the_user
1 LIST "" "*"

and see if it is there?

Here is the output:

So, yes, the Mail Folders in question are indeed listed above.

Waiting for your feedback, I decided to remove the restored folders (Grants Active.European*) in case it makes any difference. After removing them I also did:

# doveadm -v force-resync -u userx Grants\ Active
# doveadm -v force-resync -u userx Grants\ Active.International

Then I asked the user to access his mailbox again, but it didn't make any difference. As in the beginning, the only two directories appearing in "Grants Active.International" folder are the following:

Grants Active.International.2324
Grants Active.International.India

which are the two newest ones (all the others are the same with those in the initial "Grants Active.European" folder which was renamed to "Grants Active.International").

I look forward to your advice and assistance. What may be causing the mailbox to not open the rest of the folders?

Thanks a lot,
Nick
