[SOLVED] Enabling instant messaging after upgrade

[xyzz]

Hi,

we are running ZCS network edition (5.0.16_GA_2921.UBUNTU8 UBUNTU8 NETWORK edition), recently upgraded from some unknown previous release.

I tried to enable XMPP messaging service with "almost FAQ" command sequence:

zmprov mcf zimbraXMPPEnabled FALSE
zmcontrol stop
zmcontrol start

zimbraXMPPEnabled is TRUE and after restart ... noting happened.

$ zmprov gcf zimbraXMPPEnabled
zimbraXMPPEnabled: TRUE

Is there something else that needs to be enabled for domain/user?

solved.

Modifying class of service was also required.

Either:

zmprov mc default zimbraFeatureIMEnabled TRUE
zmprov mc default zimbraFeatureInstantNotify TRUE

or:
Admin Console > Configuration > Class of Service > (cos) > Options
