Cache is a component of Microsoft Project that stores your project data locally on your computer, the concept exists to boost the speed in which data is retrieved. The functionality works in such a way that when you save a project for the first time, all the data information about that project is saved in the cache. Subsequently when that project is opened, the data displayed is from the cache and only the updates are retrieved from the Project Server. Also, after editing the project, only the recent changes are updated to Project Server.
A challenge that could arise from the cache in Microsoft Project is that at some point you may encounter difficulty or errors in opening, saving or publishing a project. This is often caused when projects are checked in forcefully. A likely solution to this is to clear your Microsoft Project cache using the simple steps below:
- Open Microsoft Project, Click Options;
- Select the ‘Save’ option and click on ‘Clean Up Cache’;
- Select ‘Projects not checked out to you’ from the ‘Project Filter’ option;
- Choose the name of the project you want the cache to be cleared and click ‘Remove from Cache’;
