Hello,
to publish your Office solution to Microsoft AppSource, you must first create a developer account. You register for a developer account using your Azure Active Directory (Azure AD) business account.
To create an Office developer account in Partner Center, make sure you have the following:
- Authorization to sign legal agreements on behalf of your company.
- The official company name, address, and primary contact for your company (this can be you).
We verify this information during the account creation process.
You can create an account in two ways:
- If you are new to Partner Center and do not have a Microsoft Network account, create an account on the Partner Center registration page.
- If you are already registered for the Microsoft Cloud Partner Program, create an account directly in Partner Center with existing Microsoft Partner Center registrations.
If you are new to Partner Center, follow the instructions in this section to create your account.
- Go to the Partner Center registration page.
- Sign in with a business account so that you can associate your company's business email account domain with your new Partner Center account. Associating these accounts allows your company's employees to log in to Partner Center using their business account usernames and passwords.For information about whether your company already has a business account, and information about creating a new business account or setting up multiple business accounts for use with Partner Center, see Your company work account and Partner Center.
- Specify your publisher profile. Your publisher profile contains your company information, publisher information, and contact information.
- After confirming your publisher profile information, agree to the terms in the Microsoft Office Agreement and select Accept and Continue to create your Partner Center account. You must be authorized to act on behalf of your company to accept these terms.
If your client already has an existing Partner Center registration, the drop-down list displays a list of accounts from which you can choose. Select an account, and your Office registration will be associated with the same accounts.
If this is helpful, please accept the answer. Thank you.
