After Upgrade Mobile Devices Stop Working

After upgrading to a new Zimbra Collaboration Server, there have been many reports where mobile devices are unable to connect right after the upgrade. There have been reports of this happening after an upgrade to, ZCS 8.0.8, 8.0.9, 8.5.0, 8.5.1, and 8.6.0.

  • Note: The information shown in this wiki article works only if Mobile Devices were able to sync to ZCS before the upgrade.


First you can take a look at the sync.log to see if there is any activity in the log that may describe the problem:

tail -f /opt/zimbra/log/sync.log

If the sync.log is not active, at an appropriate time, try restarting mailboxd, and the MTA services:

su - zimbra
zmmailboxdctl restart

Then issue this command on your MTA server:

su - zimbra
zmmtactl restart

Then check sync.log to see if devices are able to sync to ZCS.

If this does not resolve the problem do try to undeploy and redeploy the mobilesync zimlet.

Run the below command to undeploy the zimlet.

zmzimletctl undeploy com_zimbra_mobilesync

To deploy the zimlet again, Run the below command.

cd zimlets-network/
zmzimletctl deploy

Flush the zimlet cache

zmprov fc zimlet
