I have a couple of Gmail accounts that were sync’ed when I added the Hubspot email integration. I’d like to only used one of these accounts. I followed the steps in the Google Account to remove Hubspot access on the account I don’t want to integrate but I still see the icon. Is there a way to remove that icon. I can see in Hubspot settings that just one account is integrated so not sure why the Hubspot icon and integration info is still showing up.
So you did this: Remove access to HubSpot in your Google account and the extension icon is still showing.
Did you also do this: Uninstall the HubSpot Sales email extension or this: Disconnect or reconnect your inbox from HubSpot
Try following those last 2 articles, they should help resolve whatever part is still connected. 
Thank you! I had completed the first suggestion. The second suggestion did the trick. Thanks again!
Awesome @JHowells glad that did the trick. With most integrations, disconnecting is a multi-step process.
Just an update - I did have to reinstall the Hubspot Chrome plug in to the Gmail account I wanted to use. The solution removed the plug in from all Gmail accounts. I reintalled after un-syncing the Gmail accounts and it worked perfectly. Thank you!
Wonderful!
