I am getting a olmapi32.dll error when starting outlook 2013, I searched for a solution but few applied to Office 2013. This is what happened. I had office 2010 which worked fine, I then upgrade to 2013 and work with it for about a week, then upgraded to windows 8, the windows 8 upgrade went well, but then when I attempted to load outlook I received that error. I had wanted to re-install office 2013, but that appears no to be an option when I run setup.
Thanks
Steve
I use it without any error but installed directly on a Windows 8 PC.
You should run the setup again for Office 2013 and it should give you the option to "repair" the current installation.
