Configure EAS in the iOS Mail App

This article applies to recent versions of SmarterMail Enterprise. View articles for SmarterMail 16.x and earlier.

Microsoft EAS is available as an optional add-on to SmarterMail. Unlike other synchronization methods, EAS uses direct push technology to sync email, calendars, and contacts to the iPhone in real time.

Once you have Activated the Microsoft Exchange ActiveSync add-on and enabled Exchange ActiveSync for the specific SmarterMail mailbox, you will need to set up an Exchange account to use with the iOS Mail app.

To set up your iPhone to access Exchange ActiveSync, follow these steps:

  1. On your iPhone, open the Settings.
  2. Tap Passwords & Accounts.
  3. Tap Add Account.
  4. Tap Microsoft Exchange.
  5. Initially, fill out the following fields:
    • Email -- your full email address.
    • Description - A friendly name for the account, such as your company name, "Work Email" or whatever.
  6. You may be prompted with a screen that asks "Sign into your "" Exchange account using Microsoft?" -- If so, choose the "Configure Manually" option. Otherwise, you will be asked to sign in with a Microsoft School or Work account, or a personal Microsoft account.
  7. You'll be prompted for your account password.
  8. Clicking Next will bring up the options you want to sync: Mail, Contacts, Calendars, Reminders and/or Notes. Select the items you want to sync.
  9. Hit the Save button.
In your accounts list, you'll see the new Account set up, using the friendly Description you configured. You can click on the new account to turn on or off synced features, or change the "Mail Days to Sync" -- this will default to 1 month, but you can change it if needed. 

And that's pretty much it: you can open the iOS Mail app, and the new account will be there and ready to use.

Hi there, how do you set the "Display Name" (from) to show the name instead of the email address on iPhone? There is no field and it just shows the email address. Not great for spam, people seeing messages are from a certain person, etc. Running SM 11 with ActiveSync. Please help - thanks! Dennis

Dennis - unfortunately, this is a limitation of how Exchange ActiveSync is implemented in iOS. By default, iOS takes the email address and uses that. There's no way to modify it so that a friendlier display name shows on an iOS device.

iPhone recently upgraded to ISO 12, and now my iPhones keep coming back with "Password Incorrect" when I configure ActiveSyn, What gives?

Hello, Heber -- Make sure you've upgraded to the most recent release as it's working just fine with iOS 12.

Hi, We have 15 Exchange ActiveSync email accounts configured on iPhones and iPads. After iOS 12 got released, none of our ActiveSync accounts are working anymore. We have tried to delete the accounts and to reconfigure them, but with no luck. We just had our server admin to update our SmarterMail to the latest version, but still the same issue. It says "Password Incorrect". The ActiveSync is activated on our server with a 25-license version. Our server version is: SmarterMail Enterprise Version - 16.3.6855. I appreciate if you have any ideas for how to solve this issue, since it is a hassle not being able to read and send emails from the phone.

This is currently being looked at. Other customers who have seen this are attempting to connect to a mail domain that does NOT have a valid SSL certificate. Therefore, if you are using a mail domain without SSL attached, the suggestion is that you get SSL set up for your mail domain. This appears to resolve the issue.

Thanks Derek!
So a multi-domain SSL (SAN) certificate should work (without EV) on all of our domains?

Jan-Tore Øvrevik (10/11/2018 at 4:21 PM)
Got SSL installed and configured for the webmail domains and was able to configure the Exchange email accounts on the iPhone without any problems after that. Thanks for your help here Derek.
