Microsoft Office Security vs Calendar File Token

[Carlos_Correa3]

Hi Folks,

Wondering if anyone else is having this issue, lately we are detecting that people who try to open our ICS file produced from a Calendar File Token are getting a Microsoft Outlook Security Notice warning, (see image below) this is having people think twice before putting the webinars in their calendar. This only seems to affect Outlook, Google Calendar or any other ICS do not seem to be bothered by this. Anybody also encountering this? or is there anything to be done?

Thanks in advance!

This is a bug Microsoft has acknowledged (as much as they publicly acknowledge anything).

It doesn’t have anything to do with Marketo, but rather with overzealous security added to Outlook. And it’ll affect all ICS files sent to the recipient from anywhere, even internally.
