How to Sync Android with Zimbra Contacts and Calendar

You can use the open standards CardDAV and CalDAV to easily synchronise your Zimbra Contacts  and Calendars to your Android smartphone.

Android has no native CardDAV client but some are available from the Google PlayStore and F-Droid.org. We now recommend the free DavX which works really well. We talk you through configuring that client but essentially any others that are available will be similar.

Once you install DavX it will appear in the Android Account Sync area, but simply starting DavX will give you the option to Go to accounts & Sync.

Select Add Account, and choose Login with URL and username as the account type.

The server name is eg https://mail.opensure.net.

Enter your email address and password.

The app will then check the connection and ask for an account name for you to identify the configuration by, eg the email address. Change this as or if desired. Leave the groups as separate VCards.

Your contacts and calendar (and Tasks) are now able to sync.

To change which calendars and address books will sync, open the Accounts area under Android Settings and click on the DavX section listing the DavX accounts. Select Manage Accounts and Click on the account shown that you want to configure. Select the Calendars and Contacts from the list that you want to sync to/from your phone.

The Settings Cog under each accounts area will allow you to more finely configure things like intervals, connections etc.

How to Sync Android with Zimbra Email

You can use the open standards called IMAP and SMTP to synchronise your Zimbra email to your Android smartphone.

Android has several email clients available but we recommend an open source one called K-9, free from the Play store or F-droid.org. Here we talk you through configuring that client but others will be similar.

You are connecting to your Zimbra account via IMAP (to fetch incoming email) and SMTP (to send emails) which allows connection to your mailbox.

To configure K-9 for zimbra ensure you are connected to the Internet then start K-9:

Then select Menu, then Add Account…:

Enter your name, email address and password, then press Next:

Select IMAP account type:

Check the user/password is correct then move to the IMAP server box and enter eg zimbra.opensure.net

Select Security as SSL or StartTLS

Port 993(leave IMAP Path Prefix as default).

K-9 will now check the configuration before moving on to the outgoing server.

In Outgoing Mail Server section, enter server as mail.opensure.net server then press Next:

Security is StartTLS if available and the port should be 587 (not 25).

Authentication should be PLAIN and the user/password should be the same as for IMAP.

Click Next and wait until it has finished verifying configuration.

Give this account a name that makes sense to you, eg Simon’s OpenSure Account and then give the name that shows when you send message eg Simon Sayes.

Then click Done and the account is ready for use.

Save the account:

Confirm.

Back to account settings page, still need to fix SMTP port as mail.opensure.net prefers to listen on the correct port not (the wrong) default port 25, open account settings:

Open Account Info:

Open SMTP page:

Choose Primary Server: mail.opensure.net

Adjust SMTP port: 587

Back to Account Info, open Advanced settings:

Enable SSL on IMAP port:

How to Sync Thunderbird Contacts and Calendars with Zimbra

Configuring Thunderbird and TB-Sync to synchronise your Contacts and Calendars on our Zimbra service.

Again we recommend using Zimbra Desktop to do this but if Thunderbird is your thing then here is how you can do a neat synchronizing trick with the smart set of add-ons: TB-Sync and Provider for CalDAV & CardDAV.

Setup Add-ons in Thunderbird to sync Zimbra Contacts (and Calendars)

First we assume that Thunderbird is properly installed and configured ready for your OpenSure Zimbra email account.

In Thunderbird Menu select Add-ons.

Search and install the add-ons ‘tb-sync’ and ‘provider for caldav and carddav’

When installed, manage the Tb-Sync add-on and add a new CalDAV/CardDAV account with Automatic Configuration.

Give your account a new name to refer to it, then your username is your Zimbra email address and then enter your Zimbra password too.

All your account’s calendars and contacts lists are shown in the listing from which you can select as many as you need or want.

Then you can use and sync all the Contacts and Calendars from Zimbra within Thunderbird.

How to Sync Outlook email with Zimbra

Configure Outlook email client to use the Zimbra email service

This is designed to help you setup a new account in Outlook for your new mailbox. We recommend Thunderbird (www.mozilla.com the same people who write Firefox web browser – also recommended) as a free and powerful mail client in preference to Outlook as it is a standards compliant approach and works very well with modern mail systems. However, this is about what you want to do so here you go!

To configure Outlook to use a Zimbra email account:

  • In Outlook, click Accounts on the Tools menu.
  • In the Internet Accounts dialogue box, click Add, and then click Mail
  • In the Display name box, type the name that you want other users to see when you send a message, and then click Next.
  • In the E-mail address box, type the e-mail address for the account that you are using (for example, type my.name@domain.here), and then click Next.
  • In the E-mail Server Names box, click IMAP for the incoming mail server type (POP3) is the default type)
  • Type mail.opensure.net as the incoming (IMAP) and outgoing (SMTP) servers and Click Next.
  • Type your IMAP account name and password in the Account name and Password boxes then click Next.
  • In the Internet Mail Account Name box, type a name to identify the mail account, and then click Next and Click Finish.
  • You should now be able to highlight this new account in the Internet Accounts window and then select ‘Properties’ When in this window click Advanced.
  • In the Advanced window tick Incoming Mail – This server requires a secure connection SSL – the Port will automatically change to 993.
  • Above this is the Outgoing Server equivalent tick box. You should set the SMTP service to StartTLS on port 587.
  • At same Properties window as when finding the Advanced tab, you will see a ‘Servers’ tab. Move to this and click the Outgoing Mail Server – My server requires authentication. Leave as using the same settings as incoming mail server.

How to Sync Windows 10 with CalDAV and CardDAV to Zimbra Contacts and Calendar

Sorry, you can no longer do this natively.

Microsoft has decided to add native CalDAV and CardDAV support to Windows 10+ but to allow only partner companies, namely Yahoo, Google and Apple to set up accounts using it. Even old hacks to get it to work, albeit not very secure, have now been closed off too.

You may have success specifically within Outlook, by using this open source software https://caldavsynchronizer.org/ or possibly https://arpdev.com/.  However, you may find adding general third party Cal/CardDAV software to let you sync other accounts may interfer with the operation of their locked down resource. 

The service MS currently include can and has in the past readily worked with ours and thousands of other services offered on CalDAV and CardDAV but they have locked all smaller and independent providers out by policy not technology. It may just be a mechanism to restrict competition to their own Exchange based 365 service.

We are sorry, but this is why we like Open Source and Open Standards – it gives you choice. With Microsoft closed software solutions it shuts down your options and you have no real free choice.

If you want a general business desktop solution that works, you can talk to us about options with Ubuntu and other Linux distributions for your desktop.

Remember Linux is what powers Android, probably many of your routers and similar tech underpins Apple’s OS.

96% of the top 1 million servers on the internet run Linux. 100% of the top 500 Supercomputers run Linux. 85% of the worlds smartphones run on Linux.
