Always when printing it appears the message "You are about to activate an OLE object that may contain viruses or may otherwise be harmful to your computer. You may want to verify that this object comes from a trustworthy source before you continue. Do you want to continue?"

    I ran into this problem last month. I believe the error message means that you have an image file in the Header or Footer of your Page Setup settings. I suspect that you are seeing a bug that Microsoft will never fix. Therefore, remove the image file (and replace it with text) and the error message will go away. Hope this helps.

    To address the OLE object error message in Microsoft Project Online Desktop Client, you can try the following steps:

    1. Check Trust Center Settings:
      • Open Microsoft Project.
      • Go to File > Options > Trust Center > Trust Center Settings.
      • In the Trust Center, look for File Block Settings and ensure that the file types you are trying to open or print are not blocked.
    2. Disable Protected View:
      • In the Trust Center Settings, navigate to Protected View.
      • You can uncheck the options that enable Protected View for files originating from the internet or other potentially unsafe locations. However, be cautious as this can expose your system to risks if you open files from untrusted sources.
    3. Move Files to Trusted Locations:
      • Consider moving the files you are working with to a trusted location on your computer. Files in trusted locations are not subjected to the same security checks and may not trigger the OLE object warning.
    4. Update Microsoft Project:
      • Ensure that your Microsoft Project is updated to the latest version, as updates may contain fixes for known issues.
    5. Contact IT Support:
      • If the issue persists, it may be beneficial to contact your system administrator or IT support for further assistance, especially if this is a recurring issue across multiple files.

    By following these steps, you should be able to resolve the OLE object error message when printing in Microsoft Project Online Desktop Client.
