Why do white boxes or white spaces appear when using background colours?

Scenario

You are using Exclaimer, and you notice that white boxes or white spaces appear when you use background colours within Microsoft Outlook. 

Reason

Unfortunately, Microsoft Outlook renders background colours and other elements within the signature itself. This is most commonly seen when using Client-Side signatures.

Although you cannot control it 100%, you can take steps to minimize this issue.

Resolution

NOTE: The steps described here assume that you have already created an email signature. For more information, see how you can create a signature.

To minimize the effect of this issue:

  1. Assign a background colour to all signature elements (text boxes and images), table cells, tables and groups.

  2. Set a Stretch alignment to all text boxes, tables and groups.
    You may need to convert some groups to tables first before moving to the next step.

  3. Reduce the gap between the rows and columns.
    Use the Rows & Columns settings to apply a Row and Column width. If required, apply a fixed width to the table.

Once you follow these steps, you will see that the white box will disappear. You may at times get the odd white line, but this is, unfortunately, something we cannot control - this is how Microsoft Outlook renders the colours.  For more information, see What do the coloured borders mean in the Exclaimer signature designer?
