I understand that you have encountered update error 30088-27 after updating Microsoft Office. I need to explain to you that this error is a known issue after the update. Usually, users who encounter this problem choose to roll back the version to successfully solve it. You can complete this operation by following the steps below:
1, Close all Office software, in the "Start menu" in the search "Command Prompt" (or "cmd"), right click and select "Run as administrator";
2, Enter the following code in the command prompt:
cd %programfiles% \Common Files\microsoft shared\ClickToRun
Enter;
3, and then enter Officec2rclient.exe /update user updatetoversion=16.0.+ Version
Officec2rclient.exe /update user updatetoversion=16.0.17726.20160
