Question : Excel workbook opens read only w/ error “Excel Workbook open by 256 Users”
“The workbook is currently open by 256 users. A maximum of 256 users can have a shared workbook open at the same time. The workbook will be opened read-only. You can try again later when one or more users have closed the workbook.”
There is no way the workbook is opened by that many users, server reboot did not solve the problem. Creating a copy of the problem only cures the issue for a few hours.
Any ideas?
Solution: Excel workbook opens read only w/ error “Excel Workbook open by 256 Users”
On the Review tab, select the Share Workbook option and see who is listed as having the workbook open. This is also a really bad idea as it happens – the Shared Workbooks feature has always been really badly implemented in Excel and should be avoided if at all possible.
