Guidho --
Here's how to do it. Assuming you are the Project Server administrator, you
should do the following:
1. Log into PWA
2. Click the Projects menu
3. Click the row header for the first project to archive
4. lick the Edit button
5. Select yourself from the Owner field
6. Click the Save Changes button
7. Repeat steps 3-6 for every project that needs to be archived
If you do not see yourself on the list of possible Owners in step #5, you
will need to add yourself to the Project Managers group in PWA. Completing
the above steps will make you the official Owner of each project, and then
you will need to do the following to become the manager of each project:
1. Launch Microsoft Project Professional and log into Project Server
2. Open the first project to be archived
3. Click Collaborate - Publish - All Information
4. Click Collaborate - Publish - Republish Assignments
5. Select the "Become the manager for these assignments" option
6. Click OK
7. Repeat steps 2-6 for every project that needs to be archived
Completing the two sets of above steps will hide each of these projects from
their former managers in both Microsoft Project Professional and in PWA.
Others who have the My Organization view permissions (such as Executives,
Senior Managers, and Administrators) will still be able to see the archived
projects. Hope this helps.
