Hi I'm running Microsoft office 2016 on a Windows 10 pc. I am having an issue opening Outlook 2016 more than once. Once I open it and close it I can not re-open outlook unless I restart my computer. When I click on outlook the blue circles goes around like its going to open but it doesn't. when I go into ctrl+Alt+ delete I can see in task manager outlook is running. Even if I close those down it won't open unless I leave the computer for sometime or I have to restart it is the only way. Any suggestions would be greatly appreciated. I have also update office but its still doing the same thing.
