• 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.

This was done using Android 10 on Samsung S20 FE with the built-in Google Mail app.

Open Settings on your phone (Gear Icon)

Tap Accounts

Tap Accounts (again)

Tap Add Account

Tap the (Gmail) Exchange option

Enter your e-mail address and tap Set up manually

Enter your password and tap Next

Your username is probably your full e-mail address

Set the server to zimbra.virtualarchitects.com

Tap Next then Done

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.

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.

1. Enter your e-mail address
2. Enter your password
3. Touch Next
4. Modify the server to be zimbra.virtualarchitects.com
5. Select Accept all SSL certificates
6. Touch Next
7. Accept the security warning
8. Set Inbox check frequency to Automatic (push)
9. Select Send e-mail from this account by default (probably)
10. Touch Next, then Next again
11. Touch Activate

1. 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.
2. 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.
3. 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.
