UPDATED (Tuesday, December 13, 2016 - 4:15 PM CST): Apple has begun rolling out a new "report junk" feature for spam iCloud calendar events. Spam invitations have become an increasingly annoying problem for many users. The feature is currently only available on iCloud.com but reports claim that the feature will be added to iOS and macOS shorty, which would make sense. This new feature is certainly no where near a permanent fix, but it should help reduce the number of spam invitations until a definite fix can be deployed.
Over the last few weeks, iCloud users have been mentioning an increase in spam calendar invitations to fake events such as Ray-Ban Sales and Ugg discounts. One of the most annoying problems with these spam invites is that declining the invite makes the problem even worse. Below we will show you how to try and avoid these annoying spam invites.
First and foremost, Apple is aware of the issue. Last Wednesday, Apple made a statement to iMore addressing the issue.
"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."
Until Apple can release a complete fix for the issue, many will still encounter frustrating situations. If you are having issues with spam invites or want to avoid the situation, here are a few tips to stay away from spam invites.
Method 1: Create a new calendar called “Spam” and move all invites that are spam to that new calendar. Then delete that entire calendar, but make sure to select the “Delete and Don’t Notify” option to make sure you won’t notify the spammers that you deleted their invitations.
Method 2: Log into the iCloud account that is receiving spam invitations, and head to Settings. In settings go to Preferences -> Advanced -> Invitations, and change your settings so calendar invitations are set to your email account, where they should be caught by your spam filter, or they can be easily trashed inside of your email. Note: This will cause ALL of your invitations to go to your email, where some legitimate invitations could be misidentified as spam.
These two methods are nowhere near perfect solutions. Many will continue to become frustrated with spam invitations until Apple publishes a fix for the issue, which there is currently no time frame for. However, Apple is aware of the issue, and is working on a fix.
