It’s possible to use HubSpot Integration in Outlook for MAC?
Only under certain circumstances. According to Install HubSpot Sales for Gmail, Office 365, and Outlook desktop :
“The HubSpot Sales Outlook desktop add-in does not support Outlook for Mac. If you use Outlook for Mac, an Outlook on the web account, or an Outlook.com account, install the HubSpot Sales Office 365 add-in instead. Additionally, HubSpot Sales is not supported in terminal server environments.”
Hope this helps.
