Ran into a little problem with Outlook 2007 today. Since migrating my PST from another machine it no longer would run the "Task Reminder". This was a bane to me as can be a little scattered brained at times at need to remind myself to do things... "call person x", "invoice x", "eat lunch"..
I tried uninstalling/re-installing Outlook and Office several times, but each fresh install would look for my old pst <- which probally created the problem in the first place
I was, however able to resolve the problem.
- re-attached my old pst [error prevailed]
- run outlook.exe /promptimportprf \\localfolder\outlook.prf
- click ok at prompt
Problem solved, the "failed to called object" in the task schedule was a well commented problem on various sites.
Glad to have it fixed now [sans 2hrs work-time].
