Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Good day,
Thank you for reaching out, and I'm sorry to hear about the difficulties you've experienced accessing your new Microsoft 365 Business Standard subscription.
When you first purchased your subscription, Microsoft sent a confirmation email to the email address you used during the purchase process.
Since you mentioned that you received an email containing a domain name in the format yourcompany.onmicrosoft.com, that email should also contain the details of your Microsoft 365 administrator account, which typically follows this format: ******@yourcompany.onmicrosoft.com.
Please use this administrator account to sign in to the Microsoft 365 admin center and manage your tenant.
Note: The email address used to purchase the subscription and receive billing notifications is often different from the administrator account that must be used to access the Microsoft 365 Admin Center for a business subscription.
If you are still unable to access the Admin Center, please send me the following information via private message:
- The email address you are attempting to sign in with
- A screenshot of the exact error message you are receiving
Once I have those details, I'll be happy to investigate further and assist you with the next steps.
I look forward to your reply and will be happy to help further.
Warm regards.
