Hello everyone!

I've performed a plenty of tests between SOGo and MS-Outlook 2013 using Activesync, Caldav Synchronizer and Internet Calendar via WebDAV, during saving time and after saving time. Brazilian daylight saving time is not applied to entire country. Araguaina is a city that will apear during the tests and it is not in Brazilian saving time. Let's go to the considerations and results.

SOGo Timezone = America/Sao_Paulo
Outlook Timezone = America/Brasilia (Outlook just have America/Brasilia and America/Araguaina)
Server Timezone = America/Sao_Paulo


Tests performed during saving time (From Nov 04 2018 to Feb 17 2019)

Events created on SOGo 4.0.4 and visualized on MS-Outlook 2013
A - Single event with one guest
 A1 - MS-Outlook 2013 Activesync
    Mouse over event shows correct time.
    If you edit this event, time is 1 hour less than SOGo and Outlook displays Araguaina Timezone

 A2 - MS-Outlook Caldav Synchronizer
    Mouse over event shows correct time
    If you edit this event time is also correct

 A3 - MS-Outlook Internet Calendar via WebDAV (Read Only)
    Mouse over event shows correct time
    If you edit this event time is also correct
    
    
B -  Weekly event with one guest    
 B1 - MS-Outlook 2013 Activesync
    Mouse over event shows 1 hour more than SOGo
    If you edit this event time is correct but Outlook displays Araguaina Timezone

 B2 - MS-Outlook Caldav Synchronizer
    Mouse over event shows correct time
    If you edit this event time is also correct

 B3 - MS-Outlook Internet Calendar via WebDAV (Read Only)
    Mouse over event shows 1 hour more than SOGo
    If you edit this event time is correct but Outlook displays Araguaina Timezone
    
    
    
    
Tests performed after saving time
Events created on SOGo 4.0.4 and visualized on MS-Outlook 2013
A - Single event with one guest
 A1 - MS-Outlook 2013 Activesync
    Mouse over event shows correct time.
    If you edit this event time is also correct but Outlook displayed Araguaina Timezone

 A2 - MS-Outlook Caldav Synchronizer
    Mouse over event shows correct time
    If you edit this event time is also correct

 A3 - MS-Outlook Internet Calendar via WebDAV (Read Only)
    Mouse over event shows correct time
    If you edit this event time is also correct
    
    
    
B -  Weekly event with one guest    
 B1 - MS-Outlook 2013 Activesync
    Mouse over event shows correct time.
    If you edit this event time is also correct but Outlook displayed Araguaina Timezone

 B2 - MS-Outlook Caldav Synchronizer
    Mouse over event shows correct time
    If you edit this event time is also correct

 B3 - MS-Outlook Internet Calendar via WebDAV (Read Only)
    Mouse over event shows correct time
    If you edit this event time is also correct but Outlook displayed Araguaina Timezone
    

Nowadays we have a lot of Activesync users in our Tine20 Groupware solution and would be necessary to fix this issue before migration to SOGo.
Anyone could give me an idea ?

Thanks in advance

Best Regards
