    Thanks Gabe_Bratton for looping me in. This is a known issue at this moment. A bug is currently open with OWA Team & worked upon for root cause determination & a possible fix.

papski2got a similar issue on two of the tenants I'm managing. 117 recipients on a sent email with BBC but only showing 16 when the user try to reply or to verify the recipients list.

Looks like there's a limitation on the OWA aplication. I've opened a case to MSFT and I'm waiting response to confirm this behaviour.

 

BTW i'm waiting an answer by client-side if they can see the complete recipients list on the Outlook heavy-client and Outlook on a mobile device, to confirm my suspicions.

 

I'll try to answer this as soon i got it confirmed.
