Your Logo Looks Oversized in Outlook on Windows
If your company logo appears enormous in an EveryoneSocial notification email, and only for people reading it in Outlook Desktop on Windows, this is an Outlook rendering limitation rather than a problem with your workspace or your logo file. This article explains the cause and what to do about it.
What you are seeing
The report usually looks like this:
- The logo dominates the email, rendering at its full source dimensions.
- It happens on notification emails from EveryoneSocial, most often Important Post Notifications and invitations.
- The same email, in the same inbox, renders correctly everywhere else.
If a recipient sees the email correctly in Outlook on the web or Outlook mobile but oversized in Outlook Desktop, this is the issue.
Why it happens
Outlook Desktop on Windows renders HTML email using Microsoft Word's engine rather than a browser engine. The Word engine ignores CSS image-scaling rules such as max-width, and when it cannot apply them it falls back to displaying the image at its native file dimensions.
This is a longstanding, industry-wide limitation of that one email client. It affects HTML email generally, not only email sent from EveryoneSocial.
The same email renders correctly in Gmail on web and mobile, Apple Mail, Outlook for Mac, Outlook on the web, and the Outlook mobile apps for iOS and Android.
What to do
Two paths, and neither requires a change to your workspace.
- Right now. Affected recipients can open the same email in Outlook on the web, Outlook mobile, or Outlook for Mac, where it renders correctly.
- Longer term. Your IT team can review the Outlook Desktop environment for affected users, including the version and build, any Group Policy settings covering email rendering, and configured image-display restrictions. This normally sits with whoever administers Microsoft 365 or your modern workplace tooling.
Does the logo file itself matter?
Your workspace logo is uploaded in Admin > Settings > Account, with a minimum width of 300 pixels. A very large source file makes the effect more noticeable in Outlook Desktop, because the fallback renders at native dimensions. Uploading a logo close to the size actually needed, rather than a print-resolution asset, reduces how dramatic the result looks in that client.
This changes the severity, not the underlying behavior. Outlook Desktop still ignores the scaling rules.

FAQ
Can EveryoneSocial fix this from your side?
Not without the client honoring standard scaling rules, which it does not. The behavior is determined by how Outlook Desktop on Windows renders HTML.
Only some of our people see it. Why?
Because it depends entirely on the email client. People on Outlook Desktop for Windows see it, and everyone else does not, even within the same company and the same email.
Does it affect what we send from EveryoneSocial to social networks?
No. This is limited to HTML email rendering. Posts and shares are unaffected.
It is still happening after we replaced the logo.
A smaller source file reduces how oversized it looks but does not stop the fallback. Route it to your IT team, or contact EveryoneSocial Support and we will confirm the diagnosis against the specific email.
