Using New Outlook on Windows for professional communication and productivity

So starnge because it was working fine no problems then all of a sudden it went down. Classic version isn't as good but it will do for now.
Yep, the older version has no bugs. They need to work out the bugs on the newer version. They know now.
For now you will need to reinstall the old version of Outlook. No problem sending emails from it!!!
No, what phone number would I use?
