Legacy Microsoft SharePoint Invitation Manager settings have retired [MC854657]

As part of MC696169 (Updated) Legacy SharePoint Invitation Manager is being retired (originally published December 2023, updated January 2024), we have retired all related settings from the Microsoft SharePoint admin center. The only setting specific to the legacy Invitation Manager (that retired late February 2024) is the setting for Guests must sign in using the same account to which sharing invitations are sent. Please note that all link sharing today requires guests to accept link sharing invitations with the account that was invited. If your users want guests to access links with a different account, users should select the Anyone link sharing setting instead.

[How this will affect your organization:]

The setting Guests must sign in using the same account to which sharing invitations are sent will no longer appear in the SharePoint admin center. As the SharePoint Invitation Manager has already been retired, there is no behavior change in the product.

We recommend using the Anyone link sharing setting, which admins can enable in the SharePoint admin center as shown below.

[What you need to do to prepare:]

This rollout will happen automatically by the specified dates with no admin action required before the rollout. You may want to notify your users about this change and update any relevant documentation.
