I use Outlook 2016 for my now redundant clear.net.nz email, and forwarding .gmail.com email address.

I do general searches in Outlook with no results appearing, since updating my account profile in Outlook from clear.net.nz to gmail.com. At first I thought perhaps I deleted a particular email I was searching for, but after scrolling through many messages I spotted it.

How do I rebuild Outlook's search, so it searches every email I've received and sent from either my clear.net.nz or gmail.com account?

Many thanks

Stevie
