It is not possible to edit a Scheduled Message after it has been created!
Messaging on the web has its own dedicated Scheduled folder which shows all scheduled messages regardless of date.
To schedule a message via the web version, please do the following::
- Click on Dashboard
- Click on Messaging
- In the left-hand menu click on Scheduled to be taken to a list of your current scheduled messages, remember, messages will appear in time and date order.
- Find the Message you would like by scrolling down the List or using the Search Bar at the top of the list.
- When you have selected the message, the content will become visible in the main content field.
Only the creator of the scheduled message can cancel the scheduled message.
