Hey @HZ20 !
Unfortunately, view-only seat users cannot use the BCC address to log emails, even though you as a core seat user can use it without personal email access.
The key restriction is that HubSpot requires “personal email access” for BCC functionality, and view-only seats don’t include this permission. So view-only users are blocked from this feature entirely, regardless of whether they’ve actually connected personal email or not.
You can find the full requirements here
Hope it helps!
Best,
Victor
