ZeXtras Review

04 Sep 2015 | ~7 minute read

In a previous article about setting up a Zimbra server, I mentioned ZeXtras when talking about mobile sync, and in particular, ActiveSync support for Zimbra. However, I feel that the quick mention of ZeXtras didn’t really do it justice, so I thought I’d write a full ZeXtras review, to show you what the suite has to offer – which is a hell of a lot more than just ActiveSync support.

Whats Does ZeXtras Offer?

Well, the basic answer to that question is – a lot. The ZeXtras suite is a collection on Zimlets (Zimbra plugins) that add a number of features to your Zimbra deployment. The plugins are as follows:

My Initial Thoughts

Deploying ZeXtras is an absolute breeze (instructions here), once it’s deployed, it instantly gets to work. The whole process is designed to be extremely easy to manage – even for novice administrators. However, if you feel like you want to get under the hood, you can also use ZeXtras via the CLI, which I found to be a lot more useful.

You don’t have to use the CLI though, that’s just what I prefer. Pretty much everything can be done from the Zimbra Admin GUI, with the use of wizards. So if you’re coming from a Microsoft background, this will really suit you.

I’ve been using ZeXtras off and on for a few months now, and so far I’ve not had a single issue with it. Everything has just worked. Which is great when you’re managing your own server! So let’s take a look at the zimlets and their features in a little more detail.


Thankfully, I haven’t really needed to use ZxBackup in anger. However, it’s always good to test your backups so you know they work before you actually have to use them. ZxBackup will backup all data for all users on a real-time basis.

You can of course set the retention policy (default is 30 days), and select which data you wish to backup, and where it’s backing up too. If you ever need to restore your data, you have a couple of options:

  1. You can restore an entire mailbox as it was at a particular point in time, to a completely new mailbox. This won’t affect the live mailbox being restored from – awesome!
  2. You can restore all deleted items from that point in time, back to any point within your retention period. It will restore to a separate folder within the users mailbox.
  3. Using the CLI, you can also restore single items.
  4. There are also disaster recovery options, just in case the sh*t really hits the fan!
  5. There are many more options in the ZxBackup Admin Guide, but these are the ones I have tested so far, and are working perfectly.


ZxMobile is so easy to use, it’s unreal. Simply enable the zimlet, then head to your mobile device and add a new Exchange/ActiveSync account. Enter your username, password, and server address, click save and you’re done! Email, contacts, calendars (including shared calendars), and tasks are all synced to your device – it’s so simple.

On my Zimbra server, I host email accounts for my family and a couple of friends, none of which are technical. The fact that all of them have managed to set up their mobile devices with very little input from myself, proves how simple it all is.


Honestly, I haven’t really played with this plugin, as I haven’t had to. I simply set it up with my default mail store (it does this out of the box), and away it went. I haven’t had to change a thing, and I haven’t had any problems. You can set up secondary mail volumes with Powerstore (I imagine this works in a similar way to Exchange Mailbox Stores). I may set up a secondary store at some point, but for now I have plenty of space and only a few mailboxes, so I don’t really need it.

You can get more information about ZxPowerstore from here.


ZxAdmin basically allows you to delegate junior admin control to other users on your Zimbra deployment. So you can allow standard users to be administrators for a particular domain. You can then set limitations on their accounts, such as mailbox limits and storage quotas.

If you’re running a large Zimbra deployment, then this could become invaluable. However, it also has it uses in a small deployment like mine. If i wanted to host mail for extended family, I could give them their own domain and let them manage it themselves. Very useful indeed.


It does exactly what it says on the tin. When deployed, it adds a chat window to the Zimbra webmail interface, so users can add other users as “buddies” and chat to them in real-time. If you have a webcam and mic, you can even do a video calls. So you basically have your own internal version of Microsoft Lync, or Skype – pretty bloody impressive, especially since it’s free!


I haven’t had to use ZxMigration yet, as I haven’t had the need to migrate from one server to another. However, the plugin allows you to completely migrate from one Zimbra server to another, even if they are running different base operating systems. More information about the ZxMigration tool can be found here


Although ZeXtras does have free plugins, the main plugins are not free. You can however get a 30 day unlimited free trial of all the plugins, there is an annual licensing fee for the suite. There are a number of bundles that you can choose from, and the minimum license number is 10. However, the licensing is extremely affordable, as shown below:

There are also discounts available for bulk orders which can grow to as much as 40%. You can configure (and buy) your license using the ZeXtras online configuration tool – it’s extremely easy to use. Once you have your license, activating it only take a few seconds, and is also very simple to do.


Overall, I’m finding ZeXtras to be a superb tool that’s cheap, easy to use, and does it’s job very, very well. If you’re looking for a way to protect your Zimbra deployment, or add extra features, like ActiveSync or extra admin abilities, then I can’t recommend ZeXtras highly enough.

I’ve had to use their community forums on a couple of occasions (more for general questions than support), and I’ve found the responses to be quick, helpful, and very useful. So not only is ZeXtras a great product, there’s a great support team behind it as well.

I hope you’ve found this ZeXtras review useful. As usual, feel free to leave your thoughts, comments, or questions below.
