Does anyone know where Exchange stores the Outlook Profile photos? The ones which appear at the bottom of emails

as photos or within a database?

Within databaseRegards from ExchangeOnline | Windows Administrator's forums

So not possible to get them out for an internal 'facebook' type project...?

Can you ask this to Exchange development forums?Regards from ExchangeOnline | Windows Administrator's forums

Active Directory includes the Picture attribute to store thumbnail photos. And you can easily import photos using the Import-RecipientDataProperty cmdlet. Here provide an article for reference. Hope it is useful.Noya Lau TechNet Community Support
