By sharing data with read or edit access, you can co-operate with internal users or external partners. You can share items like E-Mail messages, address books, calendars, tasks, folders or files. When sharing items, particular permissions are granted to the persons you share the items with.
Note the following:
In order to share data, you need to have administrator permissions for the respective folder.
The global address book cannot be shared.
E-Mail messages can only be shared with internal users, not with external partners.
Address books, calendars, and tasks can only be shared with external partners with read access, not with edit access.
If you share a folder in the Drive app, you can define whether subfolders should be shared as well.
