Frequently Asked Questions
Why does Excel crash when I save to SharePoint?
This is often caused by a software bug in specific Office builds, such as version 15601.20578. The application fails to communicate correctly with SharePoint services, triggering a fatal crash.
How can I check my current Excel version and build number?
Open Excel, click on 'File' in the top left, select 'Account' from the bottom left menu, and look under the 'About Excel' section to find your exact Version and Build number.
What is the Semi-Annual Enterprise Channel?
