I've been dealing with this issue for more than a month, everytime i chat with someone using my messenger in outlook.com ( its connected to facebook by the way ) it is showing me that i sent my message twice, well i asked my friends if they are receiving it twice, fortunately not bec it will be irritating to see my message twice but i hope i can get a resolution with this concern. im having a hard time reading my own thread bec of this repeat messages on my chat screen.

thanks!
