Hi Karsten,
Thank you for your quick response. I am aware that to utilise any ad-in features it must now be in the web version. I have followed the instructions on Set up the HubSpot Sales Office 365 add-in | Knowledge Base to add the web add in, but despite it then saying “connected to inbox” nothing is still working when I visit the Chrome outlook page.
Do you possibly know how I might be able to proceed from here?
