Microsoft has addressed a known issue causing memory or disk space errors when opening some documents using Microsoft Word, Microsoft Excel, or other Microsoft Office apps.
This known issue only affects customers who have installed Microsoft Office apps from the Microsoft Store and are trying to open an Office document that triggers the Protected View feature.
Only customers using Microsoft Office on devices running Windows 10, version 20H2 or Windows 10, version 2004 are impacted by this known issue.
Users encountering this issue will see a "Microsoft Excel cannot open or save any more documents because there is not enough available memory or disk space" error.
Microsoft has resolved the issue using Known Issue Rollback, a Windows 10 capability Redmond uses to revert buggy non-security fixes delivered through Windows Update.
Microsoft is also working on resolving a known issue causing blue screen errors on Windows 10 computers printing to some network printers after installing the March 2021 cumulative updates.
