email everyone - allow to open in web outlook not using mailto:
When opening sharing window there are three tabs:
Within a "Shared with" tab there is an option to send email to everyone, but it opens a mailto: registered client.
Allow to configure to open in Outlook web app and also allow to configure text within the message.
This will be great for onboarding process when migrating from other platforms, so users can be informed what they have access to. If there is a lot of sharing across users, the "Shared with Me" view is confusing and this can help users find the most important documents.
