Microsoft project management software used to plan, manage, and communicate a project schedule and other information among workgroup members, project managers, and other stakeholders.
A note to say we're experencing the same issues with Microsoft Project. We have tested in client enviroments and with our own copy of the Microsoft Project online desktop client. It appeatrs to have started a couple of months ago, and it can be replicated on the latest build Version 2511 (19426.20218).
The scenario is an OLE wartning pop up durng print preview, or when switching tabs in the page setup tab.
The images are inserted and have not been linked to an external source, or copp/pasted from another office app. We have tried multiple image files with no internet security locks, and the issue persists.
The only resolution to the issue is to remove images from the header/footer.
Office repairs are no use. We have tested this with a fresh install and experience the same issue. We have confirmed ole32.dll and oleaut32.dll load from C:\Windows\System32.
We have also attempted the fix listed here, without success: https://www.reddit.com/r/MSProject/comments/1jfq9it/ole_project_error/
There appear to be other reports online of the same issue recenly, suggesting a bug or change: https://learn.microsoft.com/en-us/answers/questions/5511656/ole-print-error
