Email reminder and follow up in New Outlook missing

The feature is there but currently still in a limited form.

When you select the message, you can use the Flag button in the Ribbon, click on the flag icon which shows when you hover over the message in the Message List, or right click it for more options.

Actual pop-up reminders and setting custom dates and times is still a work in progress. For now however, you could create a "For Follow Up" Search folder to keep up with your flagged items.

Appreciate the quick response Roady.

You say it's a work in progress, are Microsoft working to make it fully functioning as before?

Thanks

Nothing has been officially announced but I expect them to have full feature parity with Classic Desktop when it comes to this feature as it is an important mail triage feature for many people. Also "under the hood" it works similar to custom times and dates for Calendar Items and Tasks.

What you can actually do now as a workaround, and without switching back to Classic Outlook, is to flag the email in New Outlook, then go to the Flagged Emails section in To Do (either via the App or the Navigation on the left in New Outlook), and then set your custom Due Date and Reminder Date/Time for the item.

That's great Roady, sincerely appreciate the effort in responding.

I'll take that suggestion, good temporary solution.

If you can (in your busy schedule!), pop me a reply when you're aware an update has been made to let me know.

Thanks again and have a great day.

So a useful function that had been working for years has been removed??? Why???
