I have "Hotmail" & "Hotmail2" listed among my apps. I don't know why or how that happened. I assume, but am not sure, that they are identical. How do I combine (if not identical) & then remove Hotmail2? "Long hold" only gives "pin to start".
Try this.
Go to settings.
Go to email+accounts
See what accounts you added. If you see "hotmail2" delete it there or tap it and ummark the box Email (under Content to sync)
