I’m unable to send an email (using my hotmail account) from my cell phone

hotmail on my mobile isnt working for sending emails. i can receive but cant send.

i cant send via the webmail but not on phone.

it was working fine last night i was sending from my phone fine

my gmail and dodo accounts work fine on my mobile for sending and receiving, just hotmail isnt working

i can send from the hotmail website just not on the phone, it just fails. says unable to send. no error msg

is there an issue with m.hotmail.com (mobile platform)?

my email is *** Email address is removed for privacy ***

i also have same issue on my other accounts *** Email address is removed for privacy *** and *** Email address is removed for privacy ***
