> The ads in Outlook are if you're using the free @outlook.com email address. I'm using it with a Zoho email account and I haven't seen ads.

Not true. It’s baked into the default mail client (outlook). Outlook is now the default mail client replacing mail.

I'm using the baked-in free Outlook client right now (not the paid Office version) with both a free Outlook.com email and a Zoho email. The free Outlook.com email does show ads. The Exchange synced Zoho email isn't showing any ads.
