Excel 365 Sluggish Performance Issue: Seeking Solutions

Question

Dear All,On a daily basis, I use Microsoft Excel 365 at the office to process large-sized data as well as link it with multiple files, and so far, there haven't been any issues. However, last Monday (June 3, 2024), I experienced extreme slowness when opening large-sized data. Why did this happen? It used to work just fine.Previously, I was using Windows 10, and even after updating to Windows 11, the issue persists.Has anyone encountered a similar issue?

How about endpoint and file itself, did any update especially on security related?

Kidd_Ip&nbsp;&nbsp;Initially, I was using Windows 10. Because it was slow and there was an update available for Windows 11, I decided to upgrade to Windows 11. However, after the update, the files are still slow to open.&nbsp;
