Alright this problem should now be solved. Previously I only checked if emails outside of the Company Tool were sent and arrived.

The good thing is that even though the telegrams didnt show up in the Sent telegrams list, they were indeed sent to the reciever.

The problem occured if you sent the exact same message to different people, then it would only show up for one of them.

If I sent "Hello mate!" to Mark, Luke and John, each with some days distance inbetween, then only the first one I sent would be visible in my sent telegrams list.

But it should be fixed now
