Microsoft 365 Users Encounter Persistent ‘30088-27’ Update Errors

Many Microsoft 365 users can't update (error 30088-27). There is a temporary fix involving reverting to a prior version.


Users of Microsoft 365 and various versions of Microsoft Office are experiencing repeated “30088-27” update errors. The problem affects those using 365 and Click-To-Run (C2R) installations of , 2019, and 2021.

User Feedback and Microsoft's Reaction

Reports from Microsoft's community forums and other forums such as tenforums indicate that users are receiving the message: “Something went wrong. We're sorry, we ran into a problem while looking for updates. Please check your network connection and try again later.” Through Microsoft support, users confirmed that the issue also impacts the latest Office version, 2406 (Build 17726.20126).

A moderator on the Microsoft community board suggested reverting to the prior version and advised disabling automatic updates until a new release is released. The moderator noted that network issues have been excluded as a cause, implicating that the problem started after updating to Office version 17726.20126.

How to Address the Error

To mitigate the issue, users are recommended to open Command Prompt with administrative privileges and run these commands:

 cd %programfiles%\Common Files\Microsoft Shared\ClickToRun
officec2rclient.exe /update user updatetoversion=16.0.17628.20164#

After reverting to the previous version, automatic updates can be disabled by going to File > Account and selecting “Disable Update” under “Update Options.”

Issues Persist with Temporary Solutions

Microsoft has not yet commented on the ongoing issues in response to BleepingComputer's queries. Two months ago, Microsoft issued a temporary resolution for a different issue where users couldn't reply to encrypted emails via the Outlook Desktop client.

Recently, Microsoft also rolled back a fix that was generating false security alerts with ICS calendar files after December security updates. Additional problems include synchronization failures of Outlook desktop clients with email servers via Exchange ActiveSync and connection issues for Outlook.com users on both desktop and mobile.
