Hi,

Outlook 2013 (all updates) with IMAP server 993 (SSL), root folder path: "INBOX.", timeout 1 minute

Scenario:

1. Emails are sent since user closes Outlook at end of day

2. Next day: start computer, open Outlook

3. No new mail, even though mails were sent overnight

4. Half a day later Outlook fetches emails like nothing happened

Thunderbird is working, also web clients.

Please see log for not detecting new emails.

Last is log after I clicked several times in between Send/Receive, Inbox and Sent, then it sees new emails. If you click only on Send/Receive it does not detect new emails.
