I'm using Outlook Legacy...and have checked my incoming and outgoing server settings with my ISP (Spectrum). I have an annual 365 subscription.

Hardware is iMac with M4 chip and OS 27.2

Hope this is the right venue to get some help

Thank you

    If you would please, a few questions to help narrow the possible culprits:

    1 -- What exactly is not syncing: new incoming mail, sent mail, folders, or all mail?

    2 --Does the Spectrum account work normally if you sign in to Spectrum webmail?

    3 -- In Outlook, do you see any error message when you try to send/receive? If so, please post the exact error.

    4 -- Did this previously work on this Mac, and if so, when did it stop working? Any other events about that same time? e.g. MacOS or Office updates.

    5 -- I see that you are using Legacy Outlook for Mac, but I also need to know what version.
