Hi @Елена Репина ,
Thanks for reaching out.
I understand you are trying to access Azure Active Directory and facing issues.
This is due to you sign into Microsoft services tenant (f8cdef31-a31e-4b4a-93e4-5f571e91255a) as a standard user with restricted access.
This error usually occurs when you sign into Azure Portal using your personal account which is not added as an external/guest user to an Azure AD tenant.
You can ask the global administrator to invite you as a guest user as mentioned here: https://learn.microsoft.com/en-us/azure/active-directory/external-identities/add-users-administrator#add-guest-users-to-the-directory. When you accept the invite sent to you via email and added to tenant, then you can also create your own tenant navigating to https://portal.azure.com/#create/Microsoft.AzureActiveDirectory.
Once you are added to an azure tenant then you accept the invite sent to you via email, which will provide you the access.
Hope this will help.
Thanks,
Shweta
