Last published : Jun 07, 2026
Before you migrate users from the Folder Sync option to the Exchange Online Folder Sync option, you must understand the following aspects:
  • Before you enable users for Exchange Online Folder Synchronization, make sure that these users are disabled in Folder Sync.
  • If the users are enabled at both the places, then only the data received from the Exchange Online Folder Sync option is updated. However, the data received from the Folder Sync option is not considered while updating the folder structure.
