Problem

On ZCS v8.5.x and higher versions folder list is not visible in left panel of webclient when logging in.


Solution

  • Check if all mailbox servers are listed in the zimbraReverseProxyAvailableLookupTargets
  • Check if zimbraMailReferMode is set to "reverse-proxied" for all mailboxes.
  • Since ZCS v8.0.x the attribute zimbraReverseProxyAvailableLookupTargets overrides the old attribute zimbraReverseProxyLookupTarget
    If zimbraReverseProxyAvailableLookupTargets is empty, the proxy will use the mailbox servers that has zimbraReverseProxyLookupTarget" enabled
  • To fix this problem add all mailbox servers to the zimbraReverseProxyAvailableLookupTargets and set zimbraMailReferMode to "reverse-proxied".
zmprov mcf +zimbraReverseProxyAvailableLookupTargets <mailbox server>  
zmprov mcf zimbraMailReferMode reverse-proxied

Confirm this is the same in the server configuration for all the mailbox servers:

zmprov gs {mailbox-server-zmhostname} zimbraMailReferMode
  • Now restart mailbox service and proxy service to take changes
zmmailboxdctl restart  
zmproxyctl restart

The idea here is to find the mailbox where the affected user is and add it to zimbraReverseProxyAvailableLookupTargets.
