How to edit and change your signature in Outlook 2019 / 365 / 2016 emails?

Applies to: Outlook 2019, 365, 2016, 2013; Both on Windows 7/8/10 and macOS.

Here’s a question that we received from a reader who wanted to add his footer signature text in Office Outlook 365:

Hello folks. A customer of mine sent me a note that had a quite fancy signature in the bottom, complete with his name, address, contact details. Wanted to ask you how can i auto insert a signature of my own into my Outlook email. Note that i use multiple email accounts concurrently – Gmail for business usage and for personal; so i would like to have couple of signatures defined. Is that possible? If so, how?

Hey – thanks for the question. Setting your custom signatures for outgoing email messages is pretty simple with Microsoft Outlook. As i am now setting up my new Outlook 2019 installation, i would like to explain the process using that version.  That said, the process is almost identical for other Outlook versions.

Backup your Outlook signatures

Couple of readers asked me about where does signatures get saved in Windows, so that they can backup their Outlook email signatures when needed. When switching computers, the already defined personalized signatures can be copied over the network/hard drive or OneDrive and then incorporated into Outlook.

In Windows 7/8 and 10, the Outlook signatures are located at the: C:\Users\<your_user_name>\AppData\Roaming\Microsoft\Signatures folder. When creating a signature several files are created in that folder, each corresponding to the different Outlook message formats: htm, rtf and txt. Additionally a folder containing additional files related to the signature is created.

So if you are switching computers and want your signatures to be available for use in Outlook, just make sure that you backup and copy the relevant files mentioned above into the same folder in your new computer; you’ll be all set.

Outlook HTML signatures

Using the HTML format is supported in both Outlook for Windows and MAC.

In Windows just make sure that your email body format is set to HTML (Text Fomat tab and then hit the HTML option).

If you are conversant with Outlook VBA Macros, then you can use the VBA method .HTMLBody allow you to embed any HTML formatted text into your email body text using VBA.

HTML graphics/animations and hyperlinks

You can add a personal touch to the signature by inserting picture (bmp, jpeg, png), animations (gif) and hyperlinks.

When editing your signature in both Windows and MAC versions of Outlook, you’ll find both the Insert Picture and Insert Hyperlink buttons that allow you to accomplish  exactly that.

In order to insert an image proceed as following:

  1. Open the Signatures dialog as shown above.
  2. Hit on the Insert picture icon
  3. Browse to your picture location in your PC.
  4. Select the picture file and hit OK.

Note: Animated files (in gif or swf formats) can also be added, however chances are that policies of different email providers might quarantine messages containing animations or delete the animated files from the email before delivering to its recipients.

That’s it for today, feel free to leave as a comment in case of questions.

  1. I have no problem making multiple signatures, but I need to change them easily. Going into Preferences then Signatures, then change the default is extremely cumbersome.
