How field security affects synchronization between Dynamics 365 and Dynamics 365 for Outlook

Securing a field in Microsoft Dynamics 365 with field level security can impact synchronization between Dynamics 365 and Microsoft Dynamics 365 for Outlook. Consider the following scenario.


We do not recommend securing a field in Dynamics 365 when the field is set to sync. Best practice is to NOT secure any sync fields. If you do decide to secure sync fields, you’ll need to do the following:

  1. Secure the field using field level security. More information: see “Set field level security” below.

  2. Change the sync direction so that sync does not attempt to update or write the field during synchronization. More information: Control field synchronization between Dynamics 365 and Dynamics 365 for Outlook

Scenario: Restrict users from changing Job Title

The Contoso company wants to promote consistent data entry. While sales personnel are out in the field, it’s easy for them to create different data entries to describe the same thing. For example, the same job title could be entered as “Construction Manager”, “Foreman”, or “Site Manager”. To prevent this, the Job Title field is secured. This has consequences for synchronization.

Set field level security

John, the Dynamics 365 admin for Contoso, sets security on several fields.

He did the following steps:

  1. Go to Settings > Customizations.

  2. Choose Customize the System.

  3. Expand Entities > Contact.

  4. Choose Fields and select jobtitle. There are a lot of Contact fields so you’ll need to advance several pages.

  5. Choose Edit.

  6. For Field Security, choose Enable > Save and Close.

  7. Choose Publish All Customizations.

John also secured the following Contact fields so they won’t appear in Dynamics 365: ftpsiteurl, governmentid

Create and configure a field security profile

John creates a field security profile and assigns sales team members to the profile.

What the user sees

Nancy, a salesperson at Contoso, uses Dynamics 365 for Outlook and creates a new contact and tracks it in Dynamics 365.

When Nancy synchronizes with Dynamics 365, she notices that the Job Title field is gone from the contact. This is because Nancy doesn’t have update rights for the Job Title field.

Nancy’s manager, with update rights to the Job Title field, fills in the field with the correct job title: Construction Manager.

Nancy synchronizes again with Dynamics 365 and now the Job Title field is in the contact with the correct title.
