After Office 365 is applied and Office 2007 is uninstalled, an issue occurs where a spreadsheet does not appear in Excel 365 when one clicks on a spreadsheet.  The spreadsheet can be opened in Excel 365 by selecting File > Open and navigating to the file.  Running an online repair or using the FIXIT IT solution (https://support.office.com/en-us/article/Uninstall-Office-2013-or-Office-365-from-a-Windows-computer-9dd49b83-264a-477a-8fcc-2fdf5dbf61d8) to uninstall  and then reinstall Office 365 will correct the issue, but these solutions are not feasible for an enterprise deployment.

Hi Bob,

Based on your description, after installing office 365 you got an error in Excel. And you can solve this issue by repairing Office or using FIX IT. You wonder to get a solution can be used for an enterprise deployment.

I suggest you use command lines to automate a Quick and Online Repair in Office.

You could use a script then use GPO to publish it to users computers.
