Sage 50 Accounts Professionall v26.3 doesn't appear to support MAPI email clients

SOLVED

I remember with previous versions of Sage 50 it was possible to send emails with any MAPI compliant email cllient.

This no longer seems to be the case, the only options that are listed in Email Defaults are Microsoft Outlook and Webmail.

Trying to google this, it looks like the option should still be there.

TIA for any help with this.
