Azure Sync Version – V2 Upgrade
With our recent improvement updates to Azure Sync, users will experience a new sync version (Version 2). See below an outline of the key changes and benefits associated with these improvements.
Admins will now find the Azure Sync Version prominently displayed in the title section of the Azure Directory Sync page.
- Enhanced User Attribution
Version 1: Only users with the account_enabled flag set to true were included, regardless of licensing status.
Version 2: Azure User Sync now exclusively includes active, licensed M365 users when creating new active user accounts. This includes users with the account_enabled flag set to true and those holding an active exchange license. This ensures that only relevant users are synced, optimizing user management.
- Seamless Account Type Modification
Version 1: Modifying a user’s account type required the synchronization process to delete and recreate the account, leading to configuration loss (Sender lists, log details, and user filters).
Version 2: In Version 2, there is no longer a requirement for account recreation during account type modifications. User types will be updated seamlessly while preserving all existing user attributes, such as sender lists, log details, and user filters. This ensures a smoother transition without disrupting user data.
- Improved Handling of Inactive Accounts
Version 1: Users with account_enabled set to false were synchronized as disabled users, causing mailflow interruptions for shared mailboxes and distribution lists.
Version 2: In Version 2, users with account_enabled set to false will be synchronized as functional accounts. This enhancement ensures uninterrupted mail flow for shared mailboxes and distribution lists, improving overall system reliability.
