If the user opening a calendar shared with them doesn't have the correct permissions, they can add the Category name to their own Category list to display it with a color. Set-MailboxFolderPermission -Identity mailboxowner\folder -User alias -AccessRights ReviewerĬreateItems, CreateSubfolders, DeleteAllItems, DeleteOwnedItems, EditAllItems, EditOwnedItems, FolderContact, FolderOwner, FolderVisible, ReadItemsĬreateItems, CreateSubfolders, DeleteAllItems, DeleteOwnedItems, EditAllItems, EditOwnedItems, FolderVisible, ReadItemsĬreateItems, DeleteAllItems, DeleteOwnedItems, EditAllItems, EditOwnedItems, FolderVisible, ReadItemsĬreateItems, DeleteOwnedItems, EditOwnedItems, FolderVisible, ReadItems To set or check the permissions using Powershell, use the Set-MailboxFolderPermission cmdlet. If you are setting the permissions in Outlook on the web, choose ' Can view all details' or ' Can edit'. With the correct permissions, the person you shared your calendar with can see the category colors you assigned to appointments: To check the permissions, right click on the calendar (in the Owner’s mailbox) and choose Properties, then Permissions. Users who have Reviewer level or better permissions on the calendar will see the calendar owner’s category colors. When looking at the Category master list while the event is selected, the category will be list as 'Not in master list'. Other users will see the categories in a white color (unless it's already in their color category list). The best thing you can do, however, is always make sure you always thoroughly read pop-up notifications in Safari and not randomly click through to load webpages as quickly as possible.Why? Only category names are visible on items when you share folders on Exchange server category colors are set per user. Apple’s efforts, however, have focused mainly on iCloud calendar invite spam, rather than spam and junk calendar events added because of Safari pop-ups. This process is significantly easier than it used to be, indicating that Apple is aware of the problem and working to make changes.Īpple also rolled out a new “Report Junk” button to iCloud Calendars, which helps users remove unwanted junk from their calendars.
You’ll need to repeat the process, however, if you’ve managed to subscribe to multiple spam calendars. Look for the “Unsubscribe from this Calendar” button at the bottomĭoing this will automatically remove all other spam events from that specific calendar from your iPhone.

The problem of calendar spam on iPhone has become so widespread that Apple has even published a video on YouTube on how to remove calendar spam. The pop-up simply asks whether you would like to add a rogue calendar subscription, and apparently many people simply tap “OK” to move on to the next screen and continue to load the web page.Īpple really needs to do something about these calendar scams. In many instances, this is a simple pop-up that will appear as a Safari dialog box when you visit certain websites. This thread is what’s put the Calendar spam problem back in the spotlight once again. A new thread on Reddit this week has garnered nearly 5,000 upvotes and is calling on Apple to roll out additional protections against these pop-ups. In fact, it’s likely to increase because the spammer knows that the account is active.Ĭalendar spam is also commonly distributed through pop-ups on shady websites. So, if you receive a Calendar invite that’s spam and simply choose the “Decline” option, the problem won’t go away. The issue with this type of spam is that, even if the user hits “Decline,” it informs the spammer that the account is active and thus encourages them to continue sending the spam. As we wrote then:Įssentially what happens in these instances is an iCloud user will receive a request for either a Calendar event or to view/share an iCloud Photo Sharing album or image. For instance, in 2016, we highlighted how iCloud users were receiving spam Calendar and Photo Sharing invitations. There are multiple ways spam calendars have been delivered to users over the years.
Despite Apple’s best efforts, however, the problem continues to affect iCloud users, and it’s once again receiving widespread attention. ICloud Calendar spam has been a problem for many users since 2016 and earlier, and Apple has made a handful of changes and improvements to remedy the situation.
