- OneDrive sharing has been available for both internal and external users since October 4, 2023. However, since Microsoft365 has strict restrictions on searching and viewing by other users, it is not possible to search by name or group when setting up sharing. Sharing is only possible when the email address is an exact match.
- Garoon messages can select a secondary group and designate its members as the destination, but they are kept as individual members in the destination, so if a member in the secondary group changes after the message is sent, the message destination will not reflect the change.
- GakuNin RDM does not allow sharing by folders or files, but it is possible to share as a project. When shared as a project, all information contained in the project will be shared.

- Folders and files in Google Drive's My Drive can have their owners changed to the user with whom they are shared, but since only one user can be designated as the owner, the current owner must change to the new owner. For example, if the current owner leaves the company without changing to the new owner, the owner of the relevant file/folder cannot be changed, and the relevant file/folder will be deleted after 360 days. Folders/files in the Google Drive shared drive are owned by the team, not the individual. Even if the creator leaves the company, there is no need to change the owner.
