Wrong display name in Sent Items

[baldgeezer]

I am seeing cases where the Display Name is being shown as incorrect in Sent Items.  This is likely due to the fact that the team email address was associated with a different user who has left the team. So something is cached somewhere. How can I clear this cached information as that individual no longer exists in the addressbook for this email account.

The display name (of sender and recipients) is taken from the email message, not addressbook. So, you can't change it. There's already a feature request to get display names from addressbook, but not implemented yet.

ok but this was a new message thread so where was it taking it from?

It was set by the sender of the message. It could be taken from addressbook (if that's a recipient name) or identities (if that's a sender name).
