We received an Excel sheet for keeping track of working hours. This Excel sheet is working fine on every Microsoft device with Office 2010 - 2016.
When we try to use the same Excel sheet on a Mac the Excel sheet can't be filled in. Excel keeps saying that it is secured by a password?? We tested it witj Office 2011 for the Mac and Office 365 2016 for the Mac. The file itself is read/writetable.
We asked the orginal sender if the Excel sheet was password protected but he said that was not the case.
Any ideas what could be the problem?
- test if we can open the excel sheet on different Windows platforms (Win 7, 8 , 10) that works ok
- test if we can open the excel sheet on different Microsoft Office versions on Windows machines (office 2010 - 2013 - 2016) that works ok
- test on a iMac to edit the sheet with El capitan latest version with Office 2011
- test on a Mac mini to edit the sheet with El capitan latest version with Office 365 version Office 2016 for Mac. Test not OK.
- test on a iMac 27" to edit the sheet with El capitan Latest version with Office 365 version Office 2016 for Mac . Test not Ok
