Currently, all users can share their data everywhere through OneDrive and email. I want to apply the approval process when users send data outside the organization.
1) Email: when the user sends an email more than 10 MB to the outside of the organization it should go for approval to his manager and once approved its send to the outsider.
2) OneDrive: whenever users send files, folders, or links from OneDrive to out of the organization it should go for approval to his manager once approve OneDrive files, folder or link will be sent to the outsider.
I think it is impossible to create a flow for above requirements as there is no trigger for Outlook " when an email is created"
The problem with the email would be that you would need an individual flow for each user's mailbox. So even if you could create one its not practical.
For the OneDrive sharing, there is no trigger that fires when a sharing link is created. So I don't see any way to intercept that either.
Data Loss Prevention Policies (DLP) in the Security and Compliance center would be the best way to address this.
That means it is impossible to do these requirement as we mentioned, correct? What do you mean with Data Loss Prevention Policies (DLP)? For my understanding, these policies can be used to control connections.
Yes, that means its impossible to achieve your requirements using Power Automate.
DLP policies can be used to identify "Sensitive Information" and then set policies about what can be done with it. Approvals is not one of the of options, but you can block sharing and then allow an override for a stated business purpose. Then you can Audit those overrides to review the stated business purpose and contact the person involved. This depends on having a governance policy that people understand about what should and should not be shared externally. But right now that's about the only way to do it. But this will work for OneDrive and Exchange.
