When Zimbra Connector for Outlook (ZCO) for a user is configured, the following error pops up :

zimbra outlook connection Licensed Failure.
You are not licensed to use the Zimbra Connector with this server. You may continue to access your local data. 
Please contact your system administrator.


ZCO is a licensed feature. Users need to have a valid MAPI license to use ZCO. Check the number of MAPI licenses on server, as well as the license validity, using :

su - zimbra 
zmlicense -p | egrep 'MAPI|Valid'

It should show the available MAPI licenses limit and validity as below :


If the count is seen as 0, it means the server doesn't have MAPI license and one needs to purchase it from Zimbra sales to use the ZCO feature and avoid the error above. Accordingly check the validity as well.
