Hi wetpawprints
Lets work this out
First off i need you to go to www.myoffice.bt.com
login with the BT connect email address, this will give you a welcome to 365 screen and will tell you what your post migration ID is
This is the address you now need to use to login to the webmail at http://login.microsoftonline.com
It is also the username you will need to use to sign in to pop.outlook.com
try using that username with the following settings
Incoming server
Server - pop.outlook.com
port – 995
connection type – ssl
ensure that this is authorised with the full email address and password including the domain i.e.@btconnect.com
Outgoing
Server - smtp.outlook.com
port – 587
connection type – tls
make sure the outgoing server requires authentication and authenticate with the same details as the incoming server
that should now send and recieve
I will note that sending can only be guarenteed on BT provided WIFI
From a post by Adrianc
"Some mobile providers do what's called 'super NAT' where all the phones in a given area are given private IP addresses (e.g. 10.3.2.1) and share a single IP on the mobile company's network. This can cause a problem if someone is 'naughty' - a whole lot of customers can get blocked because they all appear to be using the same IP address."
can you go to www.myoffice.bt.com > My Services
Login with the Primary account and then go to email summary
this will show you the migrated logins of your accounts and allow you to reset passwords etc should it be needed.
Here is the set up i did for my android tablet. I realise this is not the same but may give an idea of how to do this.
