  • Play with the image size till you find the best visual fit within your signature block
  • To make your image clickable, simply click on the image and hit the link icon from the tool strip, then add the URL you’d like the image to link to

Notice that you can’t place the image besides your signature text without the signature structure breaking. To achieve an advanced signature design with the image on the side, I recommend that you try the WiseStamp Outlook signature creator. It’s free.

Build beautiful email signatures like in the example below in just 2-5 minutes.

Set automatic Outlook 365 email signature

Set automatic email signature in outlook 365
  • To set your signature to appear automatically make sure that the 2 default signature checkboxes for “new messages” and for “forward or reply” are checked (Outlook should check them as default option).

Save your signature and you're done!

  • Click “Save”. That’s it, you’re all set up. You’ll now see your new signature each time to compose a new message
  • You can go back and change your signature at any time

How to add your signature to a single email

By default, Outlook will check  2 checkboxes at the bottom of their integrated editor. One is for automatically adding your new email signature to every new message that you send and another one is for adding the signature when you “Reply” to received emails. Be sure to uncheck either box if you don’t want Outlook to automatically add your signature.

If you uncheck both boxes you should consider simply copying and pasting your ready-made email signature into your new message window, on those occasions that you want to use it. 

Copy-pasting manually is also a good option if you like to use different signatures for different occasions. Since Outlook 365 doesn’t allow for more than one automatic signature per account.

Easily generate a professional Outlook 365 signature

Instead of working hard to create a signature using Outlook’s editor, try using a signature generator. The best part is that you don’t need to manually set up your signature in Outlook. The Wisestamp editor will do it for you with a 1-click.
