Many users love using add-ins to enhance Outlooks functionality, but sometimes add-ins can create certain problems and prevent Outlook from starting. Perform this step until you find the problematic add-in and keep it disabled.
Enable another add-in and repeat the Outlook restart cycle. Choose File > Options > Add-ins and enable one or more add-ins on the list. Press Windows Key + R and enter outlook. Remember the list of all enabled add-ins in the Available Add-ins section and disable all the selected add-ins by clearing the checkboxes. In View and manage Office Add-ins, make sure that the Manage box shows COM Add-ins and choose Go. In Outlook choose File > Options > Add-ins.

Double-click the new value and assign it a value of 1. Select the Graphics key you just created, right-click in the right panel and choose New > DWORD (32-bit) Value and name it DisableHardwareAcceleration. Right-click, select New > Key and name it Graphics. Navigate to HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\Common. On Windows 8, Win + R type regedit and press ENTER. Run regedit ( Start > Run > type regedit and press ENTER). A workaround is to open Outlook using the well-known /safe command line switch but this is merely a workaround (which in turn disables all add-ons), not a permanent solution.įor a much more reasonable resolution, try this instead: Instead of running normally, the program will hang at the “ Loading Profile” stage of launch, as though the profile is corrupt (if you haven’t already checked this, it could actually be the case instead of course). A recent update to Microsoft Office 2013 that’s being pushed out automatically to clients results in some of them being unable to open Outlook 2013.
