Hello, i have one user with large mailbox (count from comand line):
files - 31639
directories - 968
all - 7G

client soft - Outlook 2016.
when log in via WWW - see all messages and can find it (but slow).

Client can't synchronize all mailbox with outlook, cant search messages.
I use Sogo and think it is problem, so configure outlook via IMAP and the same situation.

Some folders are empty on outlook, some have only a few messages.
Log of dovecot/sogo quiet - nothing strange.
It can be serwer config problem or Outlook?

Re: Outlook and large mailbox

IMAP performance will slow down with large mailbox. You have 2 possible solutions, you can try either of them, or both of them, no conflict.

1) Tune SOGo to handle large mailbox:

2) Deploy Apache Solr for full-text indexing. This will significantly speed up IMAP search (either mail header or body):

- Solr: http://lucene.apache.org/solr/
- Dovecot + Solr: http://wiki2.dovecot.org/Plugins/FTS/Solr

We offer paid support for both of them, contact us if you need some assistance:
