Hello Cat B
Hi, I'm Karl and will be happy to help you today.
The account you used to log into this forum is a Microsoft Account which has an Outlook.com email and OneDrive account associated with it. All use the same log in credentials
In short, the email address you used to create a Microsoft Account is the same email address to be used with Outlook.com (and OneDrive) and vice versa.
The login URLs are
Microsoft Account
Outlook.com
OneDrive
https://www.microsoft.com/en-us/microsoft-365/onedrive/online-cloud-storage
*** you will be able to log in using existing credentials or create a completely new account
If you have any questions about the above - please ask
