I should like to be able to use an UK English dictionary and to be able to access the dictionary to correct or delete incorrect words which I have added by mistake.

I use 3 email addresses but have not been able to set one of these as my default so that it appears every time I create a message.  I have set default but it does not work.

 All these facilities were available on Outlook Express which I used previously. Any assistance on these points would be most welcome.  Thank you.
