Signature - Table Borders Showing

My work colleagues have outlook signatures. They use tables and the borders in their tables don't show. I created my signature in Microsoft word and made mine look very similar...

What is your exact Outlook version and build number?

There was an issue in Version 2512 which caused borders to show but that has been fixed since Version 2601. See; Classic Outlook adds table borders to signatures after updating to Version 2512 - Microsoft Support

That said; Version 2512 is no longer supported in any of the Release Channels, so if you are indeed on that version, you may be having an updating issue as well.

I'm using Office 365, which is a constantly updated subscription version of Outlook

  Yeah the same is happening for me too, and I only use outlook in my browser so I never need to update it. Not sure why this is happening, it just seems to add borders to all new signatures that have been made recently.
