I have a file that lists all my maintenance customers (Maintenance Customers.xlsx). Each customer has a hyperlink to another excel file (MIR.xlsx) with a bookmark that calls the customer's specific tab. It works perfectly the first time but clicking a second link issues a "Cannot open specified file" error. If you close the MIR.xlsx file after clicking each hyperlink it will then work but it did not used to do this. The change appeared to coincide with a new computer running Win 11 and MS 365.
