My team uses email for providing support to users. All support emails are CC'ed to the support team mailing list. But sometimes it can still happen that two people in the team are replying to the same email at the same time, and clicking on Send at the same time. The user then ends up receiving two replies.
The easiest way to solve this would be to send a reply with only the support team as recipient, telling the team that I'm typing a reply right now, but this is too troublesome. Does there exist some tool with which I can see which other people in my team are currently replying to the same email?
