How to Setup Hotmail ActiveSync on iPad device
1. From the Home Screen, tap Settings >“Mail, Contacts, Calendar” > “Add Account” > “Microsoft Exchange”
2. Enter the following in fields:
Email: your full Hotmail email address
Domain: Leave blank
Username: your full Hotmail email address
Password: your password
Certificate: Accept the SSL certificate when prompted
Mail, Contacts, Calendar, Tasks: All can be enabled.
3. After finishing the configuration, select the data to sync and tap on Save button.
iPad will connect to Hotmail ActiveSync and perform an initial sync for the selected data. You are able to push email, calendar, and contacts with Exchange ActiveSync now. Enjoy it!
After you set this up and test that it is working you can delete the other Hotmail account.
Hotmail is a POP account. But since you commented it was working until today, I would suggest you go into settings > mail > and delete the account, then re-add the account and it should be as it once was.
I'm sorry but you are incorrect, there are 2 ways to setup Hotmail:
Hotmail can be setup as a POP account or as an Exchange account, when setup using ActiveSync (Exchange) instead of POP it synchronizes all mail folders, contacts and calendars.
Ooops, misread the OP
