ZCO license error

---

Problem :

When Zimbra connector for Outlook for a user is configured, 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.

Solution :

ZCO is a licensed feature. Users need to have a valid MAPI license to use ZCO.
Check MAPI license on server using :

su - zimbra 
zmlicense -p | grep -i MAPI

It should show the available MAPI license limit as below :

MAPIConnectorAccountsLimit=10000

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.
