Hi, Christina Calkins!
A few questions:
It's a .xlsx or a .xlsm file?
Does it has macros?
If yes, any that runs at open time or before saving or closing?
Does it let you save it?
If you do, the modification date matches with your access?
When opened:
Go to Data tab, Connections group, Connections icon, and,
- are there any entries?
- select each one and click on Properties and write down the details.
But before:
Go to File tab, Options, Advances, and in the section "When calculating this workbook", check that,
- Update Links to other Documents, enabled
- Save External Link Values, enabled
Otherwise, consider uploading a sample file, removing the password or changing it to something trivial and if necessary replace sensitive data with dummy or anonymized values. Or at least the macro code that it has, in all modules and class modules (ThisWorkbook and each worksheet), and userforms if suitable.
Regards!
PS: Just in case I assumed something wrongly, check this:
Go to File tab, Options, Trusted Center, Trusted Center Configuration, External Content/Data, and confirm that:
- External Content/Data Security Configuration is set to Enable All (not recommended) or Ask The User
- Workbook Links Security Configuration is set to Enable All (not recommended) or Ask The User
