I receive emails from four different accounts in Thunderbird (two from Comcast, and two from Outlook). Most of them are working fine, but one of the Outlook accounts has not been working correctly for the last few days, apparently since the last update, 115.4.3. Emails to this one account have been delayed by several hours, sometimes by as much as twelve. I have not changed any settings at all. The emails are not in the account online, so they seem to be floating around in cyberspace somewhere before they finally come through in Thunderbird. How can I fix this?
