Been getting a bunch of this, usually in my TB TRASH folder, I think from the Outlook online server. The server couldn't retrieve the following message: Subject: "<Removed for PII>" From: "Not available" ("Not available") Sent date: 10/31/2024 2:25:02 PM The message hasn't been deleted. You might be able to view it using either Outlook or Outlook Web App. You can also contact the sender to find out what the message says. I have 2 personal email accounts: Outlook and Gmail. My client is Thunderbird. Running Win11 25H2. Far as I know, problem began recently. This is a screenshot of some messages from TBirds TRASH folder. User's image (In images) Thunderbird just tried to fetch emails. Got a notification that it could not get messages, this time from GMail. What does this mean? Outlook/Gmail servers or Thunderbird? What do I need to do?
