MANUAL EMAIL SIGNATURE FILE INSTALL INTO OUTLOOK
Step 1. Copy (to your clipboard) the email signature files that you are about to install. Most likely there will be three of them, all named exactly the same except for their extensions:
The folder that stores your signature files will open.
Step 2. Press " Ctrl-V" or RIGHT click and choose PASTE to paste your signature file(s) into this folder.
Step 3. Close the signatures folder, and this time just click the "Signatures" button:
Step 4. You'll now see the signature you just saved in your list of existing signatures. Set this signature as your default signature for new messages and for replies, save your settings and exit the signature dialog by clicking "OK".
ATTENTION: Do not edit your signature AT ALL in Outlook's signature editor. Doing so will change the fundamental way that Outlook treats the graphics in your signature, and may result in a poor display of images (enlarged and blurry). If you need to make changes to your signature, do so using the data entry form set up for your email signature program and then reinstall your signature from scratch.
You're now finished installing your signature - it should appear properly for new messages and replies. Note: If you are not seeing the images in your signature, refer to the section below on disabling image blocking.
FINAL ADJUSTMENT - DISABLING IMAGE BLOCKING (IF NEEDED)
If the graphic images (logo, social media icons, etc.) do not show up in your signature, it is most likely that you have a setting in Outlook called "Don't Download Pictures from the Internet" (commonly referred to as "image blocking") turned on. You can disable image blocking by following these instructions.
