In the last 24 hours all messages in the "Inbox" (new and old) no longer have a "From" email address and default to my email address, at the bottom of the screen is the following message "A unique identity matching the From address was not found. The message will be sent using the current From field and settings from identity Marcus Relton <my email address>". These emails once opened continue to be "unread", the option to typical options of a new email such as; delete are not available and they appear as if drafts. This is only occurring in the "Inbox", if mail is moved to another folder within the server folders or local folders the email appears and functions are normal. I read the following thread https://support.mozilla.org/en-US/questions/1457302, which only references updating the Inbox Flag Properties, however I do not have this option. See images of emails and properties for reference. (I have redacted my email address) OS is Windows 11 Thunderbird is up to date as well. I have made no changes in the last 24 hours with the exception of adding a new "Tag" for email identification. I would appreciate any help. Thanks Kristen P
