I purchased a Samsung Galaxy, and after adding my other Hotmail account to it, I was having trouble using the account on my laptop. So, I deleted it from my device and when I went back to my laptop, I could no longer send or receive messages.

It will still let me log in to the email account and see old messages, but when I try to send out a new message it just says "sending" forever and never sends.  When I tried to send myself a message from another account, it is not receiving either.

How do I tell if I deleted the account by mistake?

Please help.
