Several Outlook users on different tech forums have reported encountering the error – “The attempted operation failed. An object could not be found – (code -08004010f).” Here are some of the users’ queries:
Query 1
When trying to open newly created Outlook Templates some users receive error message, “The attempted operation failed. An object could not be found”. Most of my users can open the simple templates we created with no issue, but some get the Object could not be found error and the template goes to the draft folder. If you immediately try to open it from the draft folder, Outlook closes. If you wait a couple minutes before trying to open from the draft folder, the template will open, I have tried online repairs with no help, fully uninstalled and reinstalled Office 365 and it fixed one user but not others. The effected users can open the templates with Outlook when signed onto other machines and I can log onto the problem user PC’s and the templates open OK for me.
Query 2
