Hi hazaelmeza,
To clarify the situation, I’d like to confirm which trial version of Microsoft Project Professional 2013 do you want to work with Office 365 (or SharePoint)?
Here are three products with Microsoft Project for your reference:
1. Project Professional 2013: http://office.microsoft.com/en-001/project/project-management-desktop-software-project-professional-FX103797571.aspx
2. Project Pro for Office 365: http://office.microsoft.com/en-gb/project/project-management-software-service-project-pro-for-office-365-FX103797691.aspx
3. Project Online with Project Pro for Office 365: http://office.microsoft.com/en-ie/project/project-online-with-project-pro-for-office-365-FX104002972.aspx
Considering the queries is related to Microsoft Project, we are sorry that we have limited resources about it in this forum, which focuses on Office 365 Online services. However, we have a specific support channel regarding this kind of queries. To ensure you get the dedicated support, I suggest you post the question on the Microsoft community Office and Project Online forum for further assistance. The engineers there are specialized in handling this kind of queries.
Thanks for your understanding.
Best regards,
Mills Fan
