Additionally, the error may be triggered by problematic browser extensions—such as ad blockers or productivity toolbars—that interfere with Outlook Webmail’s scripts. The fixes below address browser crashes, conflicting extensions, and OS compatibility issues that trigger this error.
1. Clear Auth Tokens & Cache
Corrupted authentication cookies or cached login tokens can cause login loops or script errors in Outlook Web. Clearing these forces a fresh session and removes conflicts caused by outdated or invalid tokens.
2. Update or Reinstall Browser
Updating or reinstalling Chrome or Edge can fix the STATUS_STACK_OVERFLOW error by resolving memory handling issues in the browser’s JavaScript engine (V8). Updates often patch performance bugs and improve how web applications like Outlook load dynamic content. Reinstalling the browser removes corrupted files, cache, or broken configurations that may be interfering with Outlook Web’s scripts. Note: If you’re reinstalling, make sure to sign into your browser account to back up bookmarks, saved passwords, and extensions.

3. Use a Non-Chromium Browser
Outlook Web uses complex scripts to update emails and content in real-time, which can overload Chrome or Edge and cause the stack overflow error. Switching to a non-Chromium browser like Firefox—or a Firefox-based browser such as Waterfox or LibreWolf—can help resolve Outlook Web crashes, as their JavaScript engine (SpiderMonkey) may handle certain Outlook operations more reliably than Chrome/Edge’s V8 engine on older systems.
4. Upgrade Your Operating System
As mentioned above, STATUS_STACK_OVERFLOW errors in Outlook Web can occur more frequently on older versions of Windows like 7 or 8.1 due to outdated memory management systems and lack of modern Chromium support. Upgrading to a newer operating system (such as Windows 10 or 11) improves how memory is allocated for modern JavaScript-based applications, especially those handling dynamic or large mailbox content in Outlook Web.
