Microsoft Outlook bug prevents viewing or creating email worldwide.

How to start Windows in Safe Mode.

A Microsoft Outlook update released today for the desktop client introduced bugs that prevent users from creating or viewing mail.

Today, Microsoft released Outlook version 2104 build 13929.20372, and after installing the update, users of the click-to-run desktop client found that they could no longer properly view emails or create new ones.

When attempting to view an email, instead of seeing the entire message body, they only see a small portion or a single line of the email message, as shown below.

To make it even more frustrating, when creating a new email message, every time you press enter, all the previously written content will be removed, as shown below.

The Microsoft 365 Status Twitter account has tweeted that they are investigating an issue with "email message visibility in Outlook," and that Outlook on the Web is unaffected.

In an incident status message in the Microsoft 365 Admin Center titled 'EX255650: Issue affecting viewing email content in Outlook', Microsoft suggests users use web and mobile clients until the issue is resolved.

Title: Issue affecting viewing email content in Outlook.

User Impact: Users may be unable to view email message content within Outlook.

More info: Initial reports indicate that Outlook on the web is unaffected and users with access to Outlook on the web can view email messages there while we work on a solution.

Initial reports indicate that impact is specific to the Outlook client and users with access to other protocols, such as Outlook on the web or the Outlook mobile app, can view message content in those platforms as a potential workaround.

Scope of impact: This issue could affect any user attempting to view an email message in the Outlook client.

If you are experiencing this issue in Microsoft Outlook, users have reported that you can fix the bug by rolling back to a previous Microsoft Outlook version!

BleepingComputer has tested this method, and it resolved the problems in our Outlook desktop client.

To roll back to the April 23rd, 2021, release and fix the Microsoft Outlook problems, please follow these steps:.

If you do not want to roll back to a previous version of Microsoft Office or cannot find the ClickToRun folder,  you can launch Microsoft Outlook in Safe Mode to fix the bugs until an update is released.

It should be noted that when starting Outlook in Safe Mode, all add-ins will be disabled, including security add-ins.

To start Outlook in Safe Mode, please follow these steps:.

It should be noted that you need to repeat this procedure every time you want to start Outlook in Safe Mode.

If you want to prevent Microsoft Office from autoupdating to this buggy version, you can temporarily disable updates?

Microsoft fixes Outlook 'Cannot send this item' email bug.

I had just clicked to read an email and everything in the body of every message went blank except for one random line.

I noticed that Outlook could print the whole body of the email, so that was the only way to read the full message.

I noticed that assistant could read out loud the full body of the email too and that images would open on internet explorer!

What a weird issue though, I was concerned that because I wanted to register to your site and I couldn't see email text bodies that I could not also read the verification mail to register (sort of chick and egg, which came first quandary).

It should launch the Office Updater at shown in the article, go through the motions, and when done you should be able to relaunch Outlook with the older version!

As a temp solution, you can also start outlook in safe mode until they fix the problem to avoid having to uninstall things.

It IS limited in safe mode as far as addons and layout goes, BUT, it works...

I have the same problem as aerhart - I wonder if it's because I'm using the 32 bit version of Office 365!

My version is Microsoft® Outlook® for Microsoft 365 MSO (16.0.13929.20206) 32-bit?

Does running Outlook in Safe Mode help!

Windows key+ R and then in the Run field enter outlook /safe and press the OK button.

officec2rclient.exe /update user updatetoversion=16.0.13901.20462.

Very much appreciated as wasnt looking forward to reset all desktops in the morning, can now remote update, your a star.

For those who do not have a Click2Run version, or are having issues with the steps, I have added an additional method to run in Safe Mode until a fix is released!

It's not a full-featured mode but will let you read and create email!

officec2rclient.exe /update user updatetoversion=16.0.13901.20462.

officec2rclient.exe /update userupdatetoversion=16.0.13901.20462.

Rollback worked correctly, tried the safe mode method but still had the same problem.

Yes, it works in safe mode!

Rollback didn't work for me either, as for jschwab I just got the message that Office is up-to-date.

Safe mode works.

Added a section on how to disable Microsoft Office updates until Microsoft releases a fixed version.

Outlook - File - Options - Mail - Editor Options - Advanced - Check box (Use the Insert key to control overtype mode

When composing a new email, the problem was gone

Then, I did an Office Update through Office Account/Update

I opened Outlook, and it is still working, but with a newer version than the above (16.0.13901.xxxxx)

This is what I got after the Outlook self-update (second update) on both computers:

It seems that something went wrong the first time Outlook/Office did the update, but after downgrading the version to 16.0.13901.xxxxx and then self-updating, it healed itself

I just went to Safe mode to get my critical email messages out ASAP

Method 1: Roll back Microsoft Office to latest April 2021 release - works

The cool kids have been using Outlook web client for years now #worklikeits2021

- if client has a domain controller Add script to group policy or logon script would recommend testing this first
