A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
I first reported this problem back in May 2022 (I am a Microsoft 365 subscriber). Contacted MS support, and after the usual time-consuming steps that made no progress, eventually got escalated to Tier 3 support. Then spent MANY hours working with Tier 3 technical staff over several months to try to solve it, countless uninstalls, reinstalls, download of third party monitoring tools, etc. The claim was that it was a unique problem to me, that others were not seeing it. This thread makes it clear I am not alone. We finally gave up in September, managed to get the function working after a complete wipe down of both Macs having the problem, reinstall of the OS and latest 365 package. Case was closed. Worked properly for a few months until about a month ago. I replied on the contact I had for Tier 3 support, we shall see it that goes anywhere...
I am convinced there is a bug in Office software, perhaps just Excel. Some file gets corrupted or erroneously saved at some point - could be upon saving of a file, or exiting or restarting Excel, or during a software upgrade, unclear. But it can appear suddenly, even without a software update, on a version where it works fine, then it doesn't the next time you start up Excel on the same version.
I am not willing to go down the 3rd party solution. I am paying MS for this to work. I am getting very tired of doing the total removal of Office and reinstalling, whether it is the latest version of going back. I have seen this on too many versions to make that viable for me.
Come on, Microsoft. Surely you can figure out what is happening and fix it.
