To create an email signature on Outlook 365, follow these steps:
Remember that your signature should be simple and professional. Avoid fancy fonts and bright colors. Make sure all the information is correct and up to date.

To add an automatic email signature to every outgoing message on Outlook 365, you first need to access the Mail section. Click on Settings, represented by a gear icon, at the top right of your window.
From the dropdown menu, choose Mail, then select Compose Messages. This is where you’ll find the Signature option. Click on the Signatures button to open the signature management window.
To add a new signature, click the New button. Name your signature and type the text in the appropriate field. You can also use the formatting option to customize your signature.
Finally, don’t forget to check the box "Automatically include my signature in new messages I compose". This way, your signature will automatically be added to every new message you create.
This is also where you can choose to apply the signature to all your outgoing messages, or just for specific types of correspondence (e.g., only for replies to existing emails).
To change or modify your signature in Outlook 365, the process is similar to creating a new signature. However, instead of clicking 'New,' select the signature you want to modify from the list in the signature management window. You can then make your changes in the text field.
After making your changes, don’t forget to click 'Save' for the changes to take effect.
Including logos or images in your Outlook 365 signature can add a visually appealing and professional touch to your emails. To do this, you need to first have your logo or image in format .bmp, .gif, .jpg, or .png.
Here are the steps to follow:
You can also adjust the image size directly in the editor if needed. If you want to add a link to the image, such as your website or social media page, click on the image and then click the link icon (which looks like a chain).
If you need to set up multiple signatures, knowing where to choose which signature to include in your emails will be very useful!

Managing your Outlook 365 signature from a mobile device is entirely possible and no more complicated than on a computer. Indeed, the Outlook mobile app gives you the ability to create, modify, and manage your email signature with the same ease and options as the desktop version.
The option is typically found in the app’s settings under the mail section. Just choose the "Signature" option, then type or modify your signature text as desired.
However, there is one limitation to consider: unlike the desktop version, the mobile app does not allow you to insert images into your signature. You can only add text.
As you can see, Outlook 365 offers many features to allow you to create, add, and modify email signatures in a user-specific manner. However, when it comes to managing and deploying uniform email signature templates and easily editable ones for 50, 500, or even 5,000 users... it’s a whole different story!
