As much as I love and use Microsoft Products, they sometimes make bad decisions or introduce very annoying bugs. This article addresses a bug introduced on 16-Dec-2025 in Microsoft Outlook Version 2512 (Build 19530.20038 Click-to-Run) Current Channel.
The issue is that email signatures using a table will now have the border showing by default regardless of whether it was showing before the update.
Microsoft have done many great things over the years but have also made some bad (maybe awful) decisions in my opinion. This includes discontinuing Zune and Windows Phone and Xbox Kinect as well as the addition of Clippy to Office or the removal of the Start Menu in Windows 8.
However, the latest change that I am less than impressed by is the changing of the default Office font (technically Typeface) from Calibri to Aptos. This article explains how to restore Calibri as the default in Microsoft Outlook.
