  • @Microsoft will future versions of Edge have the capability of opening .mht files? It would be great if in Outlook when I select ‘click here to view it in a browser’ that the message would open in Edge instead of IE11.
    I use a [mobile app car service] 4-5 days a week and receive receipts via email that need to be converted to .pdf for to be submitted for reimbursement. When printed from within Outlook the formatting of the receipts is distorted, and sometimes text and graphic content is missing, on some occasions only blank white pages were generated after doing a CRTL+P > Print to PDF within Outlook.
    Opening and printing the receipts in IE11 generates better .pdf prints, but the formatting of the messages is still distorted (while fidelity is still better overall compared to Outlook), and it still generates examples with content missing.
    I travel 20-25 days a month and it’s not uncommon for me to have to print over a hundred receipts a month. There have been instances where I’ve had to re-print a .pdf two or three times before achieving a successful (content all present and readable). It sometimes can turn printing what should be a 100 receipts into effectively 150 or 200 when you have to check everything you print.
    Anyway, I’ve found that printing the messages in Edge via the Outlook 365 via the web yields the highest fidelity prints. Hence my desire to open messages in Edge from Outlook on my desktop.
    Also, if there’s a way to get the print quality in Outlook that I do in Edge I’m all ears. Thanks. :)

  • Correction: I’ve found that opening the messages in Edge via the Outlook 365 web portal yields the highest fidelity .pdf prints.
