ActiveSync users cannot synchronize an EAS device for the first time in an Exchange Server environment

Symptoms

A user cannot synchronize a Microsoft Exchange ActiveSync (EAS) device for the first time.

When this issue occurs, the following event is logged in the Application log in Event Viewer:
Source: MSExchange ActiveSync
Event ID: 1053
Task Category: Configuration
Description:

Exchange ActiveSync doesn’t have sufficient permissions to create the “CN=MailboxName,OU=OrganizationalUnitName,DC=domain,DC=suffix” container under Active Directory user “Active Directory operation failed on DOMAINCONTROLLER.domain.suffix. This error is not retriable. Additional information: Access is denied.

Active directory response: 00000005: SecErr: DSID-031521D0, problem 4003 (INSUFF_ACCESS_RIGHTS), data 0”.

Make sure the user has inherited permission granted to domain\Exchange Servers to allow List, Create child, Delete child of object type “msExchangeActiveSyncDevices” and doesn’t have any deny permissions that block such operations.

Cause

This issue can occur if the Owner Rights security principal does not have Full Control permissions on the user account that is trying to synchronize the EAS device.

Resolution

To work around this issue, assign the Exchange Servers group the right to change permissions against msExchActiveSyncDevices objects. To do this, follow these steps:

  1. Start Active Directory Users and Computers.
  2. Click View, and then click to enable Advanced Features.
  3. Right-click the object where you want to change the Exchange Server permissions, and then click Properties.
    Note You can change permissions against a user, an organizational unit, or a domain.
  4. On the Security tab, click Advanced.
  5. Click Add, type Exchange Servers, and then click OK.
  6. In the Apply to box, click Descendant msExchActiveSyncDevices objects.
  7. Under Permissions, click to enable Modify Permissions.
  8. Click OK three times.
