Outlook 2013 not fetching new mail/synchronization issues

[Dragos Pacher]

Hi all,

 

Dovecot 2.2.10 CentOS 6 64 bit.

 

We are having terrible synchronization issues with Outlook 2013 (all
updates) on Windows 7 SP1 and 8.1 hosts (all updates).

 

Scenario: 

1.       Emails were sent since user closed Outlook

2.       Next day: start computer, open outlook

3.       No new email (even though email were sent overnight)

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

 

Second issue: folders created or email send in Outlook 2013 does not
synchronize on IMAP, they remain only local ..

 

But I am mostly interested into finding a fix for the first synchronization
issue described in scenario. Second is also important

but I have a feeling its connected to the first.

 

Any help will be highly appreciated!
