You may run into one of the issues outlined below after pasting content into your event's description. Pasted in content may include hidden HTML, inline styling, or special characters that aren’t fully supported by calendar providers. Even when content looks clean in AddEvent, those hidden elements can cause issues once the event is added to an end-users external calendar or prevent the event from being added to calendar.

An example of an error related to this is 414 URI Too Long.

Character Count Errors or Unexpected or Broken Formatting on End-User Calendars

When pasting content from another source into your event's description it often includes additional and unnecessary formatting within the code. This results in a high character count.

To avoid this, please paste in your description without formatting and add the formatting via the text editor within the event description.

Best Practices

Before pasting content into an event description:

Paste text into a plain-text editor first (e.g., Notes, TextEdit in plain text mode). Then, re-copy the text and paste it into AddEvent.
OR, paste the text in without formatting:
- Command + Shift + V
- Ctrl + Shift + V
- Ctrl + Alt + V
View description in code view to see the formatting that is added when pasting in content. Click the code option as shown below.
