After Upgrade Mobile Devices Stop Working
|This article applies to the following ZCS versions.|
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 and 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.
