Should your remark that “your personal email account has access to the shared mailbox” actually read “the Microsoft 365 user whose credentials were used to connect the Microsoft 365 Exchange e-mail account has read and write permissions to the Microsoft 365 shared mailbox”?
I have one licensed Microsoft 365 user with a Exchange mailbox and two shared mailboxes to which the former user has read and write permissions. The Exchange mailbox is connected in Hubspot as a “personal e-mail account”.
I read in the HubSpot documentation that logging e-mails only works if the HubSpot e-mail alias is in the CC or BCC field. It also works for a HubSpot e-mail alias in the TO field?
Additionally, the HubSpot Microsoft 365 Add-in dialog window does not display when selected the Microsoft 365 shared mailbox within Microsoft Outlook. How to initiate logging incoming e-mails?
