Using Zimbra with Android Mobile Devices
See also Zimbra with iOS Devices
The Zimbra Network Editions include Exchange ActiveSync (EAS) support.
The Zextras add-on package also adds EAS support to the Zimbra Open Source Edition.
Our public Zimbra platform has mobile support using the EAS (Exchange ActiveSync) protocol with 'push' notifications.
EAS will sync:
Folders
Mail
Contacts
Calendars
Tasks
All modern smart phones support 'Exchange' or 'EAS' accounts without installing any apps.
You must have Internet access from your mobile device to access e-mail! Check this first!
This was done using Android 10 on Samsung S20 FE with the built-in Google Mail app.
* Tap Accounts
To change accounts with the Gmail mail client open the client then tap the circle (or picture) to the right of Search in mail then tap the appropriate email address.
To change folders tap the 3 bars to the left of Search in mail then tap the folder.
Older Android Setup
This was done using Android 4.2.2 with the built-in Mail app.
On our public Zimbra system, you need to use your full e-mail address as your username.
Settings → scroll down to Accounts → Add Account → choose Corporate (or Microsoft Exchange or EAS)
The option to select “Exchange” may be AFTER you enter email address and password then tap Next.
Enter your e-mail address
Enter your password
Touch Next
Modify the server to be zimbra.virtualarchitects.com
Select Accept all SSL certificates
Touch Next
Accept the security warning
Set Inbox check frequency
to Automatic (push)
Select Send e-mail from this account by default
(probably)
Touch Next
, then Next
again
Touch Activate
For security, the settings changes will force the use of a numeric PIN to unlock your phone instead of using a pattern.
Troubleshooting
If you can't get the new account to work properly even when all the settings look correct, try deleting the account completely, rebooting the phone and then add the account again.
Some phones, notably certain LG phones, have faulty EAS implementations. If you can't get your Android phone to work using EAS with the built-in Mail app, try another e-mail client app. Some free mail apps:
MailWise,
Outlook Mobile.
Add the new account as Exchange/EAS/Corporate for the best results. However, you can also use POP or IMAP protocols if you have trouble with EAS.
