Configure Exchange ActiveSync on the iPhone

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

Microsoft Exchange ActiveSync is available as an optional add-on to SmarterMail. Unlike other synchronization methods, Exchange ActiveSync 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 configure the iPhone to function with Exchange ActiveSync.

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

  1. On your iPhone, open the Settings app.
  2. Tap Accounts and Passwords.
  3. Tap Add Account.
  4. Tap Exchange.
  5. Complete the following required fields:
    • Email (your full email address)
    • Server (the URL to your webmail. For example, NOTE: Do not include http:// when entering the server information.
    • Domain
    • Username (enter your full address:
    • Password
    • Description (Optional)
  6. Tap Next.
  7. If your webmail does not support SSL, the following message will display: "Exchange account verification failed."
    • Tap Next and then tap Save. Complete step 10 of these setup instructions.
    • After step 10, edit the account you just added.
    • Tap Account Info.
    • Change "Use SSL" to "Off."
  8. The iPhone will display a list of collaboration items to sync with Exchange ActiveSync. Choose from the list and tap Save to initiate the first sync.

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?

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.
