Fake Calendar Invitations Move To Microsoft Outlook
KnowBe4, Friday, March 6th, 2026
Fake calendar invites have been a problem on Gmail for years. Even though they could appear on other calendar services, I hadn't seen or read about a lot of it. Gmail had been taking the brunt of the fake calendar invites.
However, I got a scam Microsoft Outlook calendar invite recently, and other Outlook users are complaining more as well. So, what was previously happening mostly in Gmail has now moved over to Outlook, too.
I am a busy guy. I get probably a dozen calendar invites a day, on average, but I was surprised to see the following appointment in my Outlook calendar...
