New USER. How do i go back to homail after I've entered an hotmail contact/ Why am I some else OUTLOOK CONTACTS/

Could some explain it like I was  2 year old.

Thanks

pourquoi lorsque je me connecte je ne peux pas avoir de conversation verbal
¿Cómo puedo copiar los datos del calendario en otro calendario que no es de hotmail?
I'm a Scout Leader who needs to contact the parents on a regular basis. To make life easy I sorted the Scouts into ages and created groups accordingly in order to do this.
Each September new members come into the Troop and I have to update groups or create a new one. I did this today and found that when I want to send an email to the new group I have to go through a long winded process to do so. Normally I would type the first letter of the group in the "to" section and it would come up with the group. Now I have to go into "people", select the group and then send the email. My original groups still work in the previous fashion so why not the new one? I can't do this in the future as I often email differing groups and this is making it more complicated than necessary especially with approx. 50 Scouts in the Troop.
Can anyone help?
Changes made to People are not found in the TO contact list.  I now have to type in addresses, even though I've changed the contact in People the old address appears in TO contacts.
When I send out funny emails I always add comments to each one. When the replies come back they are all in one email. Why has this changed? How can I make sure that each email is read only by the person I have sent it to. Can I change back to the way it was?  Please help! Thanks
how do i know if my sent message was read?
When responding to a email, when I go to send, I get a message that Hotmail may be experiencing a problem, and to hit refresh, when I do this , my reply is delted and I have had to retype my reply 3 times, always with the same result, my reply is not saved in drafts nor does it show as sent. What can I do?
