Me and my team have been having an issue recently that every private email we send in outlook is published to hubspot as an unassigned email.
For example I just sent an email to an external email account, I got a notification on hubspot with my entire email from my name. The recipient is not a customer so should not be in the system.
I also don't have any hubspot extension in outlook, nor do I CC in the hubspot email address.
Is this what you mean? This is all of the outlook add-ins I have. I did at one point have the hubspot add-in but got rid of it weeks ago, this problem has only started in the last few days.
