SBCGlobal.net email defined as IMAP in Outlook 2016 (W10), but inbox reloads after deleting mail
Email setup in Outlook 2016 (W10) worked fine and reported back that it was IMAP.
Deleted 1000's of mail items (of the 10,400 on the account) in Outlook where they went to Trash. Suddenly, all the email began to download AGAIN into the inbox.
It's as if the Server is defined as POP with the "Keep on Server" option checked, yet the server configuration information was correctly set up as IMAP.
Why would all the mail be sent down again rather than moving to trash on the server?
(BTW, it is necessary to log into the account online to set the "Allow insecure apps to access email" option in the Account information or SBCGlobal won't allow the connection with Outlook.)
