I can't transfer photos to computer / or add to messages

[helewhely]

Hi there, hope someone can help me. I have a Huawei P8 & can't figure these issues out.

I was able to transfer photos from my phone to computer but am no longer able to, nor can I attach any photos to facebook or messages? Its like the option has gone & I can't find the setting.

The second issue is I have never been able to add my email account. Every time I try it says couldn't open connection to server, even though I am connected to the internet. Can anyone help with this?. Tia
