One of our sales reps sends an email to a given contact (that is in our hubspot crm contacts lists), using Chrome and extension. At that moment everything is ok and two items show up in Log list (contact and company).
But after sending the email, in the outbox several hundreds of contacts are added to log list, see attached. This is slowling down the computer significantly and also causing errors in the hubspot crm itself, as contacts are messed up.
What could be the reason and do you have suggestions on how to tackle this? AFAIK this only happens for 1 person using crm in our team.
