Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hi @Raman Arora,
Based on the screenshot you shared, it appears that the Granular Delegated Admin Privileges (GDAP) relationship may have either expired or been unintentionally removed. When this happens, your partner loses the delegated access they previously had, which prevents them from performing admin actions on your tenant.
At this point, even if your partner sends a new GDAP relationship request, you would still need to sign in to the Microsoft 365 admin center in order to review and accept it. Unfortunately, since you're currently unable to access the admin center at all, you won’t be able to complete that step.
Given the situation, as your partner also mentioned, the most direct and effective path forward at this stage is to contact Microsoft Support. You can reach out to them through: Customer service phone numbers - Microsoft Support
(Note: When you call the support number, you may hear an introduction of about 30 seconds such as "you can visit the link...". You can ignore this introduction and wait until you are presented with the options. Then press "1" as a business email user, and again "1" for technical help.)
