service httpd restart

Issue on Z-push Side

Some additional steps are sometimes required due to bugs etc, see the INSTALL file included with the backend for more info.

If running Zimbra backend 59 onwards fix Z-Push's RowCmp() function Within z-push/lib/default/diffbackend/diffstate.php, replace existing contents of RowCmp() with

return strcmp( $b["id"], $a["id"] ) ;

Changes on Zimbra Server ( mail.sysnetglobal.net ) side

If running Zimbra 7.2 onwards and have clients with multiple devices you need to allow them to connect simultaneously, on your Zimbra server allow an appropriate number of sessions (default is 5)

zmlocalconfig -e zimbra_session_limit_soap=7
zmconfigdctl reload

If running Zimbra 8 onwards you need to whitelist your Z-Push server otherwise its likely to get blocked by Zimbra, on your Zimbra server allow your Z-Push server's IP address

zmprov mcf zimbraHttpThrottleSafeIPs 182.50.129.154

Outlook Configuration

Make sure you use the server name ( in our case mobile.tetrain.com ) ,use of IP will not work
Please ensure the use of Outlook 13 only as other lower version will not work . Only Outlook 13 supports Active sync .
It only supports SSL based configuration , non SSL based z-push configuration will not be supported . That means we need to have Authosized SSL certificate for mobile.tetrain.com ( in our example ) and https is enabled on the Z-push server .
while configuration choose manual and then Outlook.com or Exchange Activesync service
select as shown in picture (only example)
