How unique is the drive id?

Question

I'm using Microsoft Graph to build apps that connect to files across OneDrive, OneDrive for Business, and SharePoint document libraries.

from https://learn.microsoft.com/en-us/graph/api/drive-list?view=graph-rest-1.0&tabs=http
I noticed that the API cannot directly list all drives. To list a drive, the source must be specified as in the following image.

I want to know how unique DriveId is. Are there any chances of duplicates?

Answer 1

Hello Warintorn Chomsang (Intellity Thailand),

Thank you for contacting Microsoft Support!

The DriveId in Microsoft Graph API is globally unique. Each drive in OneDrive, OneDrive for Business, and SharePoint document libraries has a unique identifier that distinguishes it from all other drives. This ensures that each drive can be individually accessed and managed without any risk of duplication.

Hope this helps.

Hi @Warintorn Chomsang (Intellity Thailand) ,

The Drive ID in Microsoft Graph is designed to be unique. Each drive is assigned a unique identifier when it is created, and this ID persists across actions performed on the drive, such as renaming or moving it. Therefore, there should not be any chances of duplicates for Drive IDs as long as the drives exist.
