Excel 365 Personal.xlsb location?

So, my question is, does Personal.xlsb have to be located in the %AppData%Excel\StartUp folder?

Thanks for reply. I've tried everything I can think of but I cannot get macros in 'Personal.xlsb' to be seen by other workbooks. It is located in a folder on my desktop and that folder is specified in the Excel Options/Advanced "At startup, open all files in" folder. That location is also in Trusted Locations. On Excel 2003, under Tools/References/Available References, there is a 'Personal.xls' box, which, if checked, allows the workbook to use the 'Personal.xls' macros. If unchecked, the macros are not available. On Excel 365, there is no 'Personal.xlsb' entry in Available References which can be checked. One thing I noticed was that on Excel 2003, the VBA project name is 'Personal.xls (Personal.xls)'. On Excel 365, the VBA project name for Personal.xlsb is 'VBAProject (Personal.xlsb)'. I've tried to change the VBA project name to 'Personal.xlsb (Personal.xlsb)', but that name is denied as illegal. VBA project name 'Personal (Personal.xlsb)' does not fix anything.

This is W10 desktop. Same issue on W10 laptop.

Correction. When I changed the VBA project name to 'Personal (Personal.xlsb)', and viewed VBA code for a book other than 'Personal.xlsb', under Tools/References Available References, the was an entry named 'Personal'. When I checked that box, the macros in 'Personal.xlsb' were available to other workbooks. And, the 'Personal.xlsb' book is not in the %AppData% tree. It is in a folder on a drive B:.

Thanks for helping.

I see that now, but I haven't seen it documented anywhere that you have to do that for Personal.xlsb if it's not in the %AppData%\Excel\StartUp folder.

Thanks.

Thanks to everyone. Problem solved.
