Can I change my Apple ID that I’ve registered?

The following may help: Change your Apple ID - Apple Support

I have also requested the hosts to remove your email address from the post. It isn't a good idea to post an Apple ID or email address on a public forum.

Edit -- they removed it even before I had a chance to report it to them!

Apple ID - Manage

My original icloud ID was set up by an IT guy for a company I worked for 5 years ago and no longer work for. He set up my default email as the company's email service, which I no longer have access to. I tried the reset instructions you recommended however it tells me those emails are already in use. I don't want to set up a fourth email identity. Any ideas to help me?

Trying to do this but your system is supposed to send a code that is required. But you never send it, told it to send again and it took several minutes or I waited several minutes and it still did not send the code. What is going on with Apple?

Posting in multiple old threads is not going to get you much help, especially when your posts don't make much sense. In your own thread, explain, in a language in which you can write about technical matters, what your problem is. What are you trying to do? What happens when you try? What troubleshooting steps have you already taken.
