Error Codes in Project Professional - 2300 & 26005

How to fix Project Professional error codes:

Unfortunately, the project in question is corrupted and it is not much you can do to fix the issue. Not a great way to start a support article, is it? But that is the reality. There is no way to fix this issue directly. Having said that, we could try a few approaches to get the project to a working state. We look at a couple of approaches below.

Technical Option:

This approach would be to save a local copy of the project and import it back into the system.

  • Open the Project for editing in Project Professional
    File >> Save for Sharing >> Save As >> Browse to select a local location to save
  • Save as a local file as MPP or as XML
  • Ensure the below setting is selected

Technical approach for error code in saving project in Project Professional

  • Once the save is complete, do a quick test to see if the file works locally and the plan has its content intact
  • Close Project Professional and open a new session of Project professional connecting to the PWA
  • Once the Project is open Project Professional, follow the Project Import process to import the Project into the Project online system as a new project
  • For the moment, the project will be a new one, please try the Save/Publish/Check in process to see if the Project is working as expected
  •  If the newly imported project works a expected, it would prove that the locally saved file works. If it does not still work, the only other option would be the functional option explained further below
  • Given the Import works, delete the newly imported Project from PWA Settings >> Delete Enterprise Objects
  • Close Project Professional and open a new session of Project professional connecting to the PWA
  • Once the Project is open Project Professional, follow the Project Import process to import the Project into the Project online system with the same name of the originally corrupted project. It will ask if the project can be replaced and please proceed
  • Test the Project again to see if it works

Functional Option:

If the technical recovery option does not work, we may have to approach this differently. The only option would be to create a new plan or approach the remaining work as a different project. It is unfortunately the last option that is possible.

  • Either the Plan is recreated from scratch. Or,
  • A new project is created with only the pending tasks and work on the project. The original project is closed for all purposes and the tasks and work from that point on are run as a New Project

So, there could very well be a question – if such an error can occur and it would lead to a lot of work to fix it, are there ways to avoid getting to this stage?

The answer is yes!

Project corruption is a bit unpredictable but most of the similar issues start with a few things:

  • The cache folder is set up on the roaming profile. When moving across networks, the cache files lose connection causing a disconnect while publishing. We have tried setting up the cache files on a local folder for a few clients which seems to alleviate the problem.
  • Project Client issues during the process of Save/Publish/Check-in could culminate in this issue. It is key to wait for each of the processes to individually complete 100% before attempting the next – especially with bigger projects where the Save/Publish/Check-in processes could take time.
  • Save changes to project plan frequently and ensure save is completed 100%. Ensure this is done before moving between networks etc.
  • Regularly Save and Check-in of project.
  • Change the configuration on your Project to allow autosaving.
  • Ensure consistency of Project Professional connectivity to the network and drives.
