Using older versions of Outlook for Mac in business environments
Dear Jim,
Thanks for your reply and let me know above information.
If you are configuring your Shaw account in Outlook for Mac as IMAP account, then the Outlook for Mac should not download the emails to the Mac and delete emails from the Shaw account server, and I also checked in the Outlook client but didn't find a setting like “delete emails from the server after download it to Mac” for IMAP account.
Given this situation, it is recommended you may kindly login to the Shaw account via the browser to see check if there is any settings in the web side that has caused this issue.
If you need further assistance, to help you more efficiently, I'd like to suggest you may post a new question in our forum because I will be out of office for more than a week so I may not be able to provide and reply to your questions timely. As this is an new questions, my colleagues will continue to help you better in the new thread rather than in this one, your understanding of this will be highly appreciated.
Wish you have a nice day :-)
Sincerely yours,
Jennifer
