When working offline, how do I prevent a message from being sent after I've clicked 'Send'?
Luis, do you mean your Mail Threshold must be defined as that for this to work when you're offline, online, or both? Thanks for the tip!
This will only work if your Mail Threshold (Mail Tab in the Location document) has been defined to wait until you have a certain number of messages in the Mailbox. If your Threshold is 1, as soon as you click send the message will be sent. It will work for sure if working offline.
