I'm hoping this post will find someone who is familiar with Apple Mac mail and Microsoft Outlook. I use Mac Mail and my emails are always accompanied by an HTML email signature. It has been brought to my attention by people who use Outlook, that when I send an email with an attachment and email signature, Outlook doesn't properly display the email. I was wondering if anyone else experiences this issue and do they know a workaround? My current workaround is to remove my signature on emails with attachments, or go directly to my online mail client and send the email from there with an attachment and signature. Both workarounds aren't ideal and I can't believe these are my only options. If anyone can help me I'd be really grateful. I've spoken to Apple directly about the issue and they couldn't assist. Screen grabs attached to show how Outlook displays emails with and without attachments.
