Hello @mattilajii and @GarthMJ,
I checked with our team that it’s expected behavior due to the Grammarly add-in and HubSpot add-in are trying to take the same space in Outlook.
I see you are also mentioning this happens when GDPR is enabled, which is correct because contact profiles will always be open with GDPR on.
So I believe the workaround that @GarthMJ offered will be the best solution to solve this case currently.
Kindly,
Pam
