dovecot - Aug 2019 - IMAP folders showing no messages in Office 365 Outlook

I'm new to Dovecot. Using Dovecot IMAP with Postfix, everything works 
fine using Thunderbird. But with the same setup, no messages show in 
IMAP folders for user accounts created in Outlook, accessing exactly the 
same server as the accounts in Thunderbird.

Dovecot version 2.3.7.1.

Is there any configuration required that is special to support Office 
365 Outlook clients? How to debug this?

Smells like a simple folder subscription issue from the client.

Try this in Thunderbird:
1. Right-click the account in the folder list.
2. Click "Subscribe..."
3. Hit "Refresh". You will probably see the folders you were looking
for.
4. Tick the folders you want to see in Thunderbird.
5. Hit "OK".

If this fixes the issue, it is a general IMAP 'feature', unrelated to
Dovecot,
I believe.

Hello Gert,

Thanks for this, but I mentioned all works fine in Thunderbird. It's 
Office 365 Outlook where the messages do not show. And I tried the same 
technique that you show, the equivalent in Outlook, and still no 
messages appear.

Hi Gert,

Well thanks to your advice and knowing that there is no specific config to
be done for Outlook, I checked the config in Dovecot more carefully. It
turns out I was using %u in the mail location instead of %n, which is what
is properly needed in my particular overall setup with Postfix and the way
I have arranged the vmail folders.

So sorry for the noise, but perhaps this thread will help somebody in the
future.
