Screen view jumps up and down erratically while typing inside a table in Outlook

Question

While typing continuous text inside a table cell in the body of an email, the view suddenly jumps to the very top of the email message and then snaps back down to where my cursor is. This erratic "bouncing" effect happens with almost every keystroke once triggered, making it nearly impossible to focus on typing.

This seems to be triggered specifically when typing inside a table, not during standard paragraph typing.

Has anyone else encountered this bug, and are there any known fixes, settings changes, or workarounds to stop the view from jumping?

I have a screen recording of the problem, but I am unsure how to attach it to this post. My current version is Outlook LTSC Professional Plus 2021, Version 2108.

Hi Gary L

Based on my research, you can try to open Outlook, go to File > Options > General.

• Under User Interface options, find the section "When using multiple displays:".
• Select "Optimize for compatibility (application restart required)".
• Click OK and restart Outlook for the change to take effect.

This setting forces Outlook to use a more stable rendering mode, which is highly effective at fixing this exact screen-jumping issue.

If the issue is still not resolved after changing that setting, you can try to type your text in Notepad first, then copy and paste it into the Outlook table as workaround. Or run an Online Repair from the Windows Control Panel to fix any underlying corrupted files.

Additionally, if the problem persists after trying the primary solution, please ensure your software is up to date:

• Update Office: Go to File > Office Account > Update Options > Update Now.
• Repair Office: Run an "Online Repair" of your Office LTSC 2021 installation from the Windows Control Panel.

I hope this information helps, if you have further questions, please feel free to let me know.

The described behavior matches known scrolling/jumping issues in classic Outlook for Windows (including Outlook 2016 and related builds) where the view jumps unexpectedly while navigating or editing content.

For Outlook 2016, Microsoft documents a similar problem and provides both a fix (in specific builds) and a registry-based workaround for affected Current Channel builds. Since Outlook LTSC Professional Plus 2021 Version 2108 shares much of the same Outlook 2016 codebase, the same mitigation is commonly used when similar scrolling/jumping issues appear.

Actionable steps:

1. Confirm build and updates
   Ensure Office/Outlook LTSC 2021 is fully updated to the latest available build for that channel. Microsoft fixed related scrolling issues in later builds of Outlook 2016:
   • First Release for Deferred Channel: fixed in Version 1705 (Build 8201.2171)
   • Deferred Channel: fixed in Version 1701 (Build 7766.2099)
   Installing the latest LTSC updates can bring in equivalent fixes for the editor/scrolling behavior.
2. Apply the documented registry workaround (if fully updated but issue persists)
   Microsoft provides a workaround that disables the experimental feature (“flight”) that causes the scrolling jump. This is done by setting two registry values for Outlook 2016; the same keys are typically used for Outlook 2016–based builds:
   • HKEY_CURRENT_USER\SOFTWARE\Wow6432Node\Microsoft\Office\16.0\Common\ExperimentEcs\Overrides
     • DWORD: ofsatqrgsry3ri0
     • Value: 0
   • HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\16.0\Common\ExperimentEcs\Overrides
     • DWORD: ofsatqrgsry3ri0
     • Value: 0
   Safer method using a .reg file:
   1. Open Notepad.
   2. Paste the following text:

            Windows Registry Editor Version 5.00
            
            [HKEY_CURRENT_USER\SOFTWARE\Wow6432Node\Microsoft\Office\16.0\Common\ExperimentEcs\Overrides]
            "ofsatqrgsry3ri0"=dword:00000000
            
            [HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\16.0\Common\ExperimentEcs\Overrides]
            "ofsatqrgsry3ri0"=dword:00000000
      

   3. Save the file with a .reg extension (for example, OutlookScrollFix.reg).
   4. Close Outlook.
   5. Double‑click the .reg file and allow it to import into the registry.
   6. Reopen Outlook and test typing in a table again.
   Editing the registry affects how Office experiments are enabled. It is recommended to back up the registry or create a system restore point before making changes.

If the issue continues even after updating and applying the workaround, capture the exact build number and consider opening a support case, referencing the known “Outlook 2016 issues with scrolling” article and the ExperimentEcs override keys already applied.
