Purview retention locations
Cloud attachments, sometimes also known as modern attachments, are a sharing mechanism that uses embedded links to files that are stored in the cloud.
It is important to note that a copy of the shared file is created whenever a file is shared and it is this copy that the retention label is applied to.
Hence, the locations you select will depend on where the file(s) is/are located or which group site the file is/are associated. So, when a user wants to send an email, if the user is a member of a Microsoft 365 group, the file might be in their Microsoft 365 group site or in the user's OneDrive, then it will be applied when the file is attached, to the new copy, that is stored in the Preservation Hold Library.
Also, when configuring the label, you should select the option to apply the retention label when the label is applied to the item.
As previously mentioned, even if there was a retention label on the file in OneDrive, it would not apply in this case as a new copy of the file will be created that will have the new retention label (to retain or delete), as defined.
Cloud attachments are files stored in SharePoint, OneDrive, or Microsoft 365 Groups that are attached as links to Outlook, Teams, and Viva Engage messages or that are referenced in interactions with Copilot. The label will be applied only to the version of the file that's being shared or referenced and does not apply to the message. As a result, you won't be able to choose Exchange, Teams, or Viva Engage as a location in the next step
I hope this helps!
