A fully managed end-to-end service for digitally signing code, documents, and applications. (formerly Trusted Signing)
Hello @Vulpisoft - Jessi,
Thank you for posting your query on Microsoft Q&A.
We understand that your sign in attempts lands you with an error that "Selected user account does not exist in tenant 'Microsoft Services' and cannot access the application '04b07795-8ddb-461a-bbee-02f9e1bf7b46' in that tenant". Typically, "Microsoft Services" appears when you're using a personal account (such as Gmail, Hotmail, or MSN) to authenticate to Azure resources, where your users may have been added as guest accounts in the tenant.
Could you please confirm whether you're using a personal account or a work/school account to authenticate?
If you're using a personal account, try directing the authentication to your tenant by using https://login.microsoftonline.com/<Replace your tenant_ID>

Hope this helps. Do let us know if you any further queries.
Thanks & Regards,
Janaki Kota
