Shared Mailbox	If you send emails from a shared mailbox, Outlook will not add your signature by itself. You must put it in by hand.
Email Format	Look at your default signature settings. Make sure your signature is set for new emails.
Email Format Compatibility	Outlook works best with HTML signatures. Set your messages to use HTML for the best results.
Version Compatibility	If you have more than one Outlook version, remove any trial versions. This can fix problems with your signature.

Image Display Issues

Images in your signature help your emails look better. Sometimes, images do not show up right. You can stop most image problems by following these tips.

Use embedded images	Embedded images are part of the email, so they do not break if the link changes.
Choose proper image formats	PNG and JPEG work well in most email clients. Do not use BMP or TIFF files.

Optimize image size	Small images load faster and look better.
