Hello Chuck,
Not sure if this is helpful, but I did locate this article:
https://www.makeuseof.com/answers/how-can-i-store-mail-locally-using-imap/ You may want to contact your email host and see if there is a server side setting they need to check that states that "messages deleted off of the server should not be deleted locally" but if you are syncing them, that is likely the issue, not sure if they can control that unless you have separate local storage like a .pst file. Hopefully some of the suggestions in the link above are helpful.
Good luck!

Subject: Emails deleting from Webmail and on Outlook
HI All.... Not sure if anyone has run into this so Im taking a chance. We have 2 computers with Outlook that are doing funny things. Our webmail accounts have 1gig of space. When the gig on webmail is full email is not working. We have IMap settings. When we delete emails from Webmail they delete on the persons computer also. They are synced together instead of unloading the emails on the computer then deleting from webmail every 10 days or so. Has anyone had to deal with this... We are stumped!!! Thanks for your help cp
