The following limits apply to all plans.
- Items and files - A list can have up to 30 million items and a library can have up to 30 million files and folders. Views can have up to 12 lookup columns. To learn more about other restrictions for viewing large lists, see Manage large lists and libraries in Office 365. A file's entire path, including its name, must be fewer than 400 characters.
