After working for 90 minutes with MS Office support ... suggested your organization.
When opening an EXCEL workbook which has worked perfectly since the beginning of year as well as yesterday, I receive a security warning indicating macros have been disabled. Checking all options macros are all enabled. Tried to run code without using shortcut and the same problem occurs. when looking at Macro listing and selecting either of the two macros OPTIONS tile is grayed out.
