OneDrive Outlook Security Policies Troubleshooting with Event Logs Registry | Intune

by

In this post, I will try to explain OneDrive Outlook Security Policies Troubleshooting with Event Logs Registry. The easiest and best way to configure Outlook security policies using Intune administrative template policies.

The following are the three policies that I configured to prevent the users from configuring personal account sync with OneDrive.

  • Prevent adding non-default Exchange account – Enabled
  • Prevent users from syncing personal OneDrive accounts – Enabled
  • Prevent users from adding e-mail account types – Enabled

NOTE! – Before the introduction of Administrative templates, we used to go through a very painful process to find the OMA-URI, CSP, string values, etc… as explained in the post – https://www.anoopcnair.com/restrict-personal-email-sync-intune/

Prevent users from syncing personal OneDrive accounts

This policy setting lets you block users from signing in with a Microsoft account to sync their personal OneDrive files. More details about enabling or disable options of this policy.

  • If you enable this setting, users will be prevented from setting up a sync relationship for their personal OneDrive account.
  • Users who are already syncing their personal OneDrive when you enable this setting won’t be able to continue syncing (and will be shown a message that syncing has stopped), but any files synced to the computer will remain on the computer.
  • If you disable or do not configure this setting, users can sync their personal OneDrive accounts.

Prevent adding non-default Exchange account

This policy allows you to prevent users from adding non-default Exchange accounts to existing Outlook profiles.

  • If you enable this policy setting, you will prevent users from adding non-default Exchange accounts via the Add New E-mail Account wizard.
  • If you disable or do not configure this policy setting, users can add non-default Exchange accounts to existing Outlook profiles.

Results – Intune Reports

I can see the policies got successfully deployed to 2 of the devices (Azure AD joined and Azure AD registered). It got failed on Azure AD Joined device probably because I logged in with local user account to that device.
