Hi @$$ANON_USER$$
If you're starting Azure training and don't feel comfortable performing the module exercises using your companies email, you can always create a Free Subscription. With the free subscription you can use any email address to sign-up and you'll get 12months of free popular and always free services along with a $200 credit to explore Azure for 30 days.
Please let me know if this helps with your issue or if you have any other questions.
Thank you for your time!
