We send emails to some people outside of our organizations and there is a button (link) so they can click and that triggers a campaign.
When the link is sent by email, the href value is replaced by another value (i.e. protection.outlook.com/?url=...). So protection.outlook.com hits the page to make sure there is no security issue and then will redirect the user to the actual page.
Problem is that the campaign is triggered twice (one by outlook hitting the page and one by the actual hit to the page.
I am not even sure if this can be fixed but is there anything that can be done to fix this issue?
