Identical mail appearance on all clients, e.g. font and size (HTML tags)
When formatting an email in Outlook for Mac, font and size may not stay when viewing the mail on a Windows mail client. The font reverts back to Times New Roman although it's formatted as Calibri in Outlook for Mac.
Outlook for Mac does not seem to include the right HTML tags.
This is tree for me even when staying on a mac. Cut and Paste from one email to another shows this issue.

Even copying text from 1 message to another changes the font size.
There's a lot of inconstancy in how Outlook for Mac is handling fonts and formatting.
