How to send email notifications to external collaborators 7 days before their access is about to expire?

Question

Hi there
In our SharePoint Online Admin Center, the settings automatically expire for external collaborations in 6 months (which is good).
How to send email notifications to external collaborators 7 days before their access is about to expire?
Any OOB way? Script? PowerShell? PowerAutomate? Anything else?

Thank you so much.

Hi @frob ,

Currently, there is no OOB settings in SharePoint Online to control how often expiration notification emails are sent. The notification emails are sent by system and does not support customization either.

Please feel free to make your features suggestions on the Microsoft SharePoint Dev Platform feedback portal on UserVoice.
