Using New Outlook on Windows for professional communication and productivity
I prefer Windows Live Mail (WLM) as well. Neither the web version nor the app version of Outlook allows you to "organize" emails by subject line; only by conversation, which is totally different. I have several types of emails that have the same exact subject line even though the contents [body] of the email are different; therefore, when grouped by "subject line", I could see/read all of those emails back to back whether the email was received today or months ago. To "organize" by "conversation" only allows replies to that one specific email be "organized" together.
In addition, it was so much easier to save an email (or multiple emails at one time) to a file folder on the computer or even to a flash drive just by sliding the/those email(s) over to that folder/flash drive. Can't do so with the Outlook web version nor the app. You have to literally "save or download" one at a time which is very time consuming because now I keep getting a download alert asking me if I'm sure, etc. In addition, as mentioned, the Outlook app only allows you to slide only one (1) email over at a time to save to your computer. You literally have to slide one at a time which is a problem as it takes up too much time to do so.
