Android E-mail

I have been trying to get my e-mail since early this morning via my Android Galaxy S6 and I keep getting the same error message. (sign in failed) I know that everything is correct. Is there an issue that I am not aware of? I have checked all over the Web and I see nothing. My e-mail works perfect on the computer, but that doesnt help me when I need my phone to send and recieve e-mails. Does anyone know if they are aware of this issue and if so maybe an ETA when the issue will be fixed?
