Using classic Outlook for Windows in business environments
Hi, Isobel49!
Thanks for using Microsoft products and posting in the community. I realize that you've encountered a problem with < Moving to New Outlook> and I understand how you feel.
You may have misunderstood. outlook does not say to stop the service. What is being discontinued is Windows Mail, and you can still use the classic version of Outlook, which is what you call the old Outlook, by clicking on the link: https://support.microsoft.com/en-us/office/outlook-for-windows-the-future-of-mail-calendar-and-people-on-windows-11-715fc27c-e0f4-4652-9174-47faa751b199
Feel free to post back if you need further assistance.
