Hi, just wondering if someone knows why I cannot send emails or reply to emails with my outlook email address.

I do not know why you're unable to send or reply to email messages. With that in mind, is the device you're using connected to the internet? Have you contacted your email provider to see if they are experiencing problems on their end? Have you properly configured your email account via Outlook or on the device you're trying to access the email?

I've been trying on my iPad and iPhone 6s, I will try it on my laptop and see how I go. I receive mail fine on iPad and iPhone but just won't let me send or reply for some reason. If it doesn't work I will contact outlook support.
Thank you

My guess would be your outgoing smtp server port is wrong or it might need authentication of some kind.
I would google the server settings for the outgoing server for your email provider and see if they have iPhone instructions.
