In Outlook signiture the compani logos are gone.

Question

vándor tamás 10

Hey, there is an issue with my email signature.

Some parts are gone and mainly the logo just disappeared.

All my colleagues have the same issue and my IT guy looked at it and the settings are correct.

We did the basic troubleshooting that we found online and my IT guy said that it is a Microsoft issue.

Is it just me or has anyone else had the same issue starting today.

Thank you in advance.

Hi @vándor tamás

Based on what you described, it sounds like Outlook is failing to load external images/media in the signature, especially since your whole team is experiencing it at the same time and your local settings are correct.

To help narrow this down and see if there is a known workaround, could you share a bit more detail?

Outlook Version: Which exact version or build of Outlook are you currently running?

License: What Microsoft 365 / Office license type are you using (e.g., Business Basic, Business Standard, Enterprise)?

Web Check: Does the issue also happen when you check your email via Outlook on the web (OWA)?

Let me know what you find, and we can go from there!

Are they now on Classic Outlook Version 2607?

In Outlook signatures [images are gone]

I'm tracking what might be a similar problem in a Reddit thread:
