How do I migrate Public Folder permissions?
Permissions for Public Folders can only be migrated from Exchange 2010+ (i.e., they cannot be migrated from Exchange 2007).
The account for the Source needs to either be an Owner of the Public Folder or be in the Public Folder Management Role Group. The Role group method resolves issues of missing ownership of a folder.
In order for Public Folder permissions to be migrated correctly, the users on the Source and Destination must be created and set up. When we migrate permissions for a Public Folder, we attempt to match the full email address first, and then attempt to match the display name of the user. If neither of these are found to match, then the permission is not migrated.
Further explanation on the process followed for permission checks:
- The migration process will first try to match the primary email address.
- If it finds a match, then permissions will migrate.
- If it cannot find a match, then it will continue on and check the display name of the user.
- If it can find a match of the display name, then permissions will migrate.
- If it cannot find a match of the display name (or the primary email address), then permissions will not migrate.
By default, Public Folder permissions are migrated for folders that do not exist. If folders already exist, permissions are not migrated.
If you would like to force permissions to be migrated when a folder already exists, you will need set the Advanced Option to migrate permissions for new folders and existing folders.
Note: Rules, such as Assistant Rules, are not migrated with Public Folder migrations.
