Following the creation of your signature template and its deployment, when you start a new email, your signature seems to have dotted borders applied to the template, even if you have not set any border in the signature design.
Be aware that once your email is sent to your recipient, no border/grid appears on your signature.
If you want to disable the dotted lines, here are the steps to follow:
- Open your Outlook mail
- New message
Generate a new email and ensure that your signature template is applied.
- Format the text
Click inside the body of the email, select the Format Text tab (in the top ribbon bar).
4️⃣ Borders Menu
Click on the dropdown menu Borders
5️⃣ Display the grid
Click on Show grid to deselect this option.
