Outlook emails not formatting to HTML since last update 28/03/23

Question

We have Outlook on 2 PCs, one running Windows 10, the other is on 11.

Both were working fine before the last update 28/03/23 and formatting to HTML

Now, despite checking all settings in Trust Centre & Options, neither PC can be made to format emails to HTML which makes it awkward to read & send mail.

Answer 1

Hi @Samantha Gibson ,

Welcome to our forum!

What's the current format of the emails? Rich Text or Plain Text?

Do you mean that all emails you send and receive are not HTML format?

If so, in order to further confirm if the issue is related to Outlook desktop client, please log in to web mail and check if the sent and received emails are displayed as HTML.

If the emails are HTML on web mail, what's the version of your Outlook? (File > Office Account > About Outlook). Please first make sure you have upgraded your Outlook to the latest version. And then confirm the below two options in Outlook client:

1. Compose messages in HTML format: File>Options>Mail>Compose messages>Compose messages in this format: HTML
2. Disable "Read all emails in plain text": File>Options>Trust Center>Trust Center Settings>Email Security>unselect "Read all emails in plain text" option:

Based on the above, if the issue still exists, considering the impact of some add ins, It is suggested that you try to start outlook in safe mode(win+R>type: outlook /safe) to check whether it works normally.

Hope the above help!

Answer 2

I have the same issue here: every message I open or compose, no matter it's HTML, RTF or plain text, is displayed awkwardly:

It's displayed the exactly same way

Answer 3

Looks like Microsoft Outlook has a new feature called "Immersive reading" I was not aware of, and it changes the way Outlook displays messages.

I changed the options and everything got right again!
