Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hello @Krienas Tarkuotas
Welcome to the Microsoft Q&A Community!
Thanks for reaching out. I understand you’re unable to sign in as the admin and need to contact Microsoft 365 Business Support.
Please find the appropriate contact information here and make a phone call: Customer service phone numbers - Microsoft Support
Once your ticket is assigned and you receive a call from an agent, please be ready to provide details associated with your subscription, such as:
- The primary domain associated with your Microsoft 365 subscription.
- Billing details associated with the subscription, such as invoice numbers or partial payment information.
- Official business information matching what is listed on the tenant profile.
Having this information prepared will help expedite the verification process.
When you call the hotline, they will ask you what kind of problem you are struggling with.
Answer: Authenticator.
A: What products do you use?
B: Office 365 for business.
Verification: Education or company account?
B: For companies
A: Are you an administrator?
B: Yes.
A: Are there any other administrators in your organization?
B: No.
A: I need one.... Service request?
B: Yes
Note:
Sometimes, you may first hear an automated voice message. Please wait until it finishes. If an agent is available, you will then be connected and receive assistance.
After submitting your support ticket, it may take some time for it to be assigned to an agent. Due to the high volume of requests, there could be delays in handling your case. Please allow 5-7 days for your ticket to reach an agent.
If your organization's Office 365 Business/Education subscription is from a partner or reseller, contact the reseller's support provider to help open a service request on behalf of you instead.
If you cannot successfully speak to a support representative, please consider creating a new tenant by signing up for a trial Microsoft 365 subscription via this link Compare All Microsoft 365 Plans | Microsoft.
Once the new tenant is set up, use its admin console to submit a support ticket requesting assistance for your original tenant. Remember to cancel the trial subscription after the issue is resolved to avoid charges.
Thank you very much for your valuable time and your cooperation. Let me know how it goes on your end or if you need further assistance.
