Configure eM Client for MAPI & EWS

MAPI/EWS is a data synchronization protocol bundle that seamlessly syncs SmarterMail Email, Contacts, Calendars and Tasks with eM Client. (Using the EWS portion of the bundle.)

NOTE: Before you can configure a mailbox to sync using the MAPI/EWS technology, you must activate the MAPI/EWS add-on. For more information, please refer to the KB article Activate MAPI/EWS.

It's also worth noting that on more recent builds of eM Client, the default autodiscover settings for any Exchange account point to Microsoft 365. That means that when using the automated setup of an account, if you're using MAPI/EWS, eM Client will fail to find your account. To work around this issue you need to edit your Registry.  Below is a screenshot of the registry entry you need to make. IF YOU ARE NOT COMFORTABLE editing your registry, we strongly recommend you simply set up your email account in eM Client as a IMAP account.

HKEY_CURRENT_USER\SOFTWARE\eM Client

AllowAutodiscoverJson = 0

1. Within eM Client, click on Menu then select Accounts from the dropdown.

   Password: Your account password
6. Click the Next button.
7. It is entirely possible that eM Client will fail to find your server settings. If this happens, enter your mail server info when asked. (E.g., mail.your-domain.com). Then, click the Next button.
8. Enter your Account details when asked. Generally, leaving this as-is is the best course of action. Then click the Next button.
9. Select your desired encryption options for use with eM Client, and click Next.
10. Select your Account avatar and Sync Options, then click Finish.
11. The new account's info will be displayed. You'll notice that the new account has an "Exchange Web Services" tab -- this ensures your connecting as an Exchange account.
