I'm wondering what font they are using.

Also what do you have here: Tools > Options > Display > formatting or Menu icon > Options > Options > Display > formatting

Default font:  ?? what have you got selected?

click on 'Advanced' Please post image of that window.

Thanks for your reply. OK I attached what you requested. Please let me know what you see. Thanks!

I see a whole lot of Microsoft word V12 source that has no place in email. Perhaps if you composed your signature using Thunderbird as we suggest the problem will go away.

See https://support.mozilla.org/en-US/kb/Signatures

I have spent countless hours with people on the topic of signatures and simply seeing some evidence of a paste from word is enough to make my blood go cold these days.

Matt is correct. The person who sent the email has been using a Word Processing Package - Microsoft Word.

I cannot see the last part of source which has the html info in the email signature, but I certainly looks like they have created a signture using MSWord and then used it in emails. Or If they are typing in Word and copy pasting into email, then they would also be bundling a load of 'hidden' html coding into the email. This has the effect of sending loads of unnecessary html code bloating the email. Cambria Math is a font which handles advanced math features eg: equations. Why they are using Cambria Math is anyone's guess.

I note you are using a Mac. It is likely that you may not have that font on your system, so your computer is using the nearest equivalent.

The sender really needs to understand that they are not producing emails that are readible. They should not create signatures using MSWord, ideally not copy/paste from eg: MSWord and they should be using a generic font that is likely to be on any OS.

You could try reading emails from this person in 'Plain Text'. View > Message Body as > Plain Text

Thank you gentlemen. Glad to have that situated.

I have set my "View > Message Board" to "Simple HTML" and can finally see ACTUAL numbers that I understand.

This forum is great. Thank you all!

@Toad, The biggest issue with Word stuff is the entire Normal.dot template is included as an inline cascading style sheet in the body of the email. It there happens o be a overlap of style names then chaos can be the result.

I think this may well be only when copy and paste is used, but I have no copy of outlook to test on these days.
