Zimbra Desktop 4.29 cannot connect to our zimbra server

[mlmpm]

Hi,

I installed the new Zimbra Desktop 4.29 and when i provide the server url, i get the invalid server error.

We run the Zimbra 8.8.7_GA_1964.FOSS server.

How can we resolve this problem.

I suspect starting with a server that's about 5 years newer would be a start. 8.8.7 is old enough to be starting primary school.

Zimbra Modern Desktop app supports only 8.8.15/9.0.0/10.0.0 server versions with latest patches
