Zimbra Connector for Outlook update

Zimbra Connector for Outlook update

If you are using our Zimbra email service with Outlook, you need to do a manual update before March 4th 2020. Check your current version of Zimbra connector – if it is not 8.8.15 you need to follow the instructions below to do the update.


The current version of the Zimbra Connector for Outlook (ZCO) contains a bug which means that auto update does not function correctly. We have disabled the auto update feature for now but from 4th March 2020 we will be enabling it again.


After the 4th, all users of the old ZCO will be prompted to update – the update will appear to complete, but will not. In such cases, the only solution is to completely uninstall ZCO, then carry out a fresh install.


The ZCO downloads are available from here:

Download Advanced Outlook Connector (64 bit)
Download Advanced Outlook Connector (32 bit)


Once this latest version of the connector is installed, auto updates should work correctly going forward.


We are sorry about the hassle this will cause. We felt the only way to mitigate some of the impact on you was by disabling auto update until a specific point in the future to give you time to arrange the manual updates.


If you need any help with the Zimbra Connector for Outlook update or you need us to do the update for you, please get in touch.
