Unfortunately, once an email account is terminated and you attempt to add a new email, there is a mandatory 30-day waiting period before you can take further actions related to the account. During this time, access to the original email account is necessary to manage the OneDrive account effectively.
To potentially regain access or manage the situation, consider the following steps:
- Contact Support: Reach out to Microsoft support for assistance. They may have options available to help you recover access or provide guidance on what to do next.
- Emergency Access: If you have set up an emergency access account (break-glass account) in Microsoft Entra, you may be able to use that to regain access to your account.
- Wait for the Period to End: If no other options are available, you may need to wait for the 30-day period to conclude before you can make any changes or regain access to the account.
It's crucial to keep track of any communications with Microsoft support for future reference.
