If the issue happens on several devices, try these steps on one device first. Then test your other devices, and follow the steps on those devices if you need to. 

Make sure the app supports the attachments

The app you're using can affect whether you can see, download, or attach a file. See the table below for details.

  • iCal for OS X Lion: You can't attach files to iCloud Calendar events with iCal. If you attach files to an event with Calendar for OS X or iCloud.com, you can see the attachment names in iCal but you can't download them.

You can attach many types of files to a calendar event, including these: 

  • Pages, Keynote, and Numbers documents. If you're attaching documents created with Pages version 5.2, Keynote version 6.2, or Numbers 3.2, you need to compress those files before you attach them.
  • Microsoft Office documents (Office ‘97 and newer)
  • Rich Text Format (RTF) documents
  • PDF files
  • Images
  • Text (.txt) files
  • Comma-separated value (CSV) files
  • Compressed (ZIP) files

Check the number and size of attachments

You can attach up to 20 files to your iCloud Calendar event, and the total size of attachments per event can be up to 20MB. Learn more about calendar limits
