My emails are in Outlook in Windows 365. Two @tiscali.co.uk addresses. Most of the time an 0x800CCC0E error appears re. receiving emails , sending emails works ok. Intermittently emails are received. 1h40min with Microsoft support reloaded the whole Outlook program [ and lost my address book] so things all worked ok for a few minutes but then same fault re-appeared. The fact that it all works sometimes indicates the settings are fine so what could be causing this ? My internet connection is fine and receiving/sending emails directly from their own sites is no problem just via Outlook.
