Apple is Investigating a Solution to Stop iCloud Calendar Spam

On Wednesday, Apple released a brief statement to iMore’s Rene Ritchie saying that they are working to address the issue by identifying and blocking suspicious invite senders. In the statement, which was shared by Ritchie via Twitter, Apple said:

“We are sorry that some of our users are receiving spam calendar invitations. We are actively working to address this issue by identifying and blocking suspicious senders and spam in the invites being sent.”

The company failed to detail exactly how they plan to solve the problem for affected users.


Over the past week, spammers have increasingly turned to Apple’s Calendar service instead of sending advertisements and other promotional content through email. Depending on system settings, iCloud Calendar invites are pushed out directly to connected iOS and Mac devices, which triggers an on-screen notification that must be accepted or denied.

If a user interacts with an iCloud Calendar invite, it will automatically send a response to the sender. This means that spammers can easily determine whether a particular account is active.

We have posted a guide that details temporary workaround which will let you block these spam calendar invites until Apple issues a fix.
