@Chris Webb I don't mean that, but I do mean For example, I have a commercial registration certificate that expires after 6 months, for example I want to set a date and get an email alert when that date comes
You can look into retention and disposition of content, but that's pretty complex and requires labeling of all documents etc.
But it sounds like you need to setup tasks or something based on that document. In this case I would have a library with a follow up metadata column and then create a flow using power automate that runs on a daily schedule and e-mail or create a task or whatever other action when that date matches the date you set in that column for the file.
Laura Rogers and Shane Young have some good content on Youtube for learning flow etc. if you want to look into going down that route.
Yeah you would want to setup a flow similar to my example above.
You can set a manual reminder using the built in reminder flow they have in libraries now under "Automate" when you select an item, you can specify to give you an alert on that date, but you have to do it for each item. I'd prefer the flow personally since you can setup your own rules and own custom e-mail etc. based on the match.
