We use and Microsoft Excel Workbook as our database and I am the primary
person that makes changes and those changes are saved on the other two
people's copies who work in the office.

This morning when I tried to save changes it would not let me and changed my
copy and their copies of the workbook to a [read only] [shared]
[compatibility mode] database.xls

This when I clicked save a box came up stating that there over 265 persons
using the database at this time. Which can't be possible since we only have 3
people in our office who use it only a daily basis.

It was always a [shared] [compatibility mode] database.

Please offer any help you can provide.
Thanks!
