Are you experiencing this problem utilizing Apple Mail or Microsoft Outlook?

Thanks for confirming the domain (ending in @cedarcomm.com).

Here are some tailored checks and troubleshooting steps for your domain:

The domain cedarcomm.com appears in the support documentation of Astound Broadband (for example, it lists @cedarcomm.com with an incoming server of mail.cedarcomm.com).

Check if you're located inn one of the listed countries below and Email and Server Settings for DC Metro, IL, IN, MA, NY and PA:

https://astound-prod.mindtouch.us/support/email-help/email-and-server-settings-for-all-markets

This implies your email account may be hosted by an ISP or third-party mail server (not necessarily Microsoft 365 native mailbox).
So you are likely using either IMAP or POP rather than Outlook’s full Exchange sync.

Because of that, you’ll want to check the incoming server settings in Outlook for Mac:

• Incoming (IMAP) server: mail.cedarcomm.com

• Port: Usually IMAP SSL 993 or IMAP non-SSL 143 (check with your provider)

• Login: your full email address

• Outgoing (SMTP) server: mail.cedarcomm.com with authentication and appropriate port (often 587 TLS)

Make sure those are correct in Outlook > Preferences > Accounts.

I use outlook.com No error messages. When I log in through my browser I can send and receive but see nothing of my unsent messages that show up on my mail on my Mac. They sit in the draft file and eventually move to the outbox.

The server that receives my emails removes everything once I open my email on my Mac. Nothing stays on the server.
