Error message - This project cannot be opened in read-write mode.. RRS feed

  • Question

  • We are getting a number of projects with error:  "This project cannot be opened in read-write mode because it is locked for updating status reports from server.   Do you want to open this project read only?"

    We are using Project Server 2013.

    Trying to open in MS Project 2013.

    Error only comes up when trying to open in Project Pro, not the browser.

    Project can be opened in the browser, and edited and saved without issue.

    Even if you click on "YES" to the error message to open in read only, the project just locks up Project Pro and never loads.

    Does anyone know how to clear this problem?

  • This might be a local cache issue. Is it happening for specific users? I'd suggest them to clean up their local cache and see if it helps.

    Hope this helps,

  • We have cleared all cache and error remains.

    • Can you provide the screenshot of the error you are getting when opening the project in project client.
    • Also can you try accessing the project from the Project client (I mean just open the project from MS Project and not from the PWA Open --> in Project Professional)
    • Ensure correct Project Server account is set. Probably try creating a new PS account for Project client and try accessing the project.

  • Solved the problem:

    It was a cache issue, but a little strange.   There are two cache areas in MS Project Pro application.   One area is for projects checked out to you and the other is for projects NOT checked out to you.    The second cache was the culprit and cleared the error, even though the project in question was not checked out.   Strange.

    Thanks for the feedback.
