How many emails have you sent, where you wished you could pull it back within seconds/minutes of clicking send? I call this the “Oh No Minute”, and Outlook can help.
I used an excellent idea found at the How-To Geek site for creating a rule to prevent the “Oh No!” reaction after sending an email you realize you didn’t mean to send. (i.e. forgot the attachment, left someone off the To: line, etc.). This rule will delay any message you send in Outlook for a period of time (in minutes). It will look like it sent, but actually is waiting in your Outbox.
I tweaked that rule a bit from the How-To above. First, mine is only 1 minute, not 5 as the tutorial above suggests. I find that you almost always “Oh No” with in 60 seconds. Second, I put in an exception to send right now if i mark the email as high importance (exclamation mark). Try it out!
