I regularly E Mail my friends. One told me when she receives my E Mails some of the text has been changed with code like letters and numbers between the words.
I asked her to send me what she got. It was not exactly as I had written it.
When I receive her E Mails... the text is partially in all caps and she did not write it this way.
What causes this strange thing?
I never heard of it before.
Thanks

Sounds like an issue with whatever email editor you're using. Are you using Outlook or some web based email program?

It must be outlook. Either on your side or on her side.
If you use the the web-mail service instead of outlook I suspect all will be fine.

Send a email to her from a web-based email service like gmail. Log into the site and send from there.

If she gets it funny, it is on her side.
If she receives if without funny letters then ask her to send it back to you. If you receive it funny then the problem is on your side.

To solve this I would suggest you create a new profile. This way it will give you a fresh new account to work with. This new account will also have all the default settings so this should work.

Warning: If you cannot set up a email account, ask the person who helped you setup up the account you currently have. You will also need you pop/smtp settings and username/password for your account.

Here is a link to help with the profile creation:
