The error may occur if you’ve recently updated Microsoft Office. The Error Code in Event Viewer will be displayed as. This Outlook installation bug only occurs on Windows 10 v2004, but Microsoft should release a fix soon. If you are generally facing this issue, here is the workaround.

1] Create a New Outlook Profile

Here is a workaround if you do not want to roll back the version of Office, however it involves creating a new Outlook profile. Open Outlook by typing outlook /safe in the Run prompt(Win +R), and press the Enter key. Click on the Options button, and then click on New. Name the profiler and add your accounts. Then comes the waiting period where you will need to rebuild mailboxes, and it will depend on the size of the mailbox. Once its done, work with the new profile until an official fix is rolled out.

2] Rollback to particular build of Office

If you want to rollback to a particular build number or change your update channel, then you can download and execute the script. The script uses the “officec2rclient” program, and updates to the older version. You can also perform the rollback manually.

Open the Command Prompt by typing “CMD” in the Run prompt (Win +R) and pressing Shift + Enter.
Change your directory to the Click ToRun folder.

cd “\Program Files\Common Files\microsoft shared\ClickToRun”

Finally, run the officec2rclient program.

officec2rclient.exe /update user updatetoversion=16.0.12827.20470

The Office version that you roll back also affects all other products. So it is better to use a different profile than downgrading the client. Also, as always, it’s good to install updates a couple of days later to see if there are any issues with recent updates.
