@Juan Carlos González MartínHi there, I want to know if Teams can feed into Project online so that staff does not have to capture on project online aswell as Teams. Is it correct that this cannot be done,but, What you can do is to publish your project plan in Project Online and add a Tab to your Project Online plan in Teams as a web tab? Once project Online is on your Teams web tab – do you then duplicate captured Teams’ hours on that tab?
What @Juan Carlos González Martín is saying is when it is added to Microsoft Teams as a Tab in a channel you work directly on Project Online through Teams. There is no duplication in doing so unless you have this information already in Teams elsewhere (I.e. in another app or on wiki).
Teams doesn't 'feed in' to Project - you are working on Project through Teams
What is the plan to bring in this capability? There is a clear need for this. If Microsoft wants enterprises to use MS Teams for project collaboration and are not providing an option to import mpp or sync with Project, it is just plan oversight from Microsoft. They should pass this feedback to the product team and get them to plan for this capability in a near future release.
