On a Mac OS device using Thunderbird 91.7.0, all the dates in the date field show the date 12/31/1969 7:00pm. if I move the emails to a different account the date is corrected. I have moved the emails to a new folder, compacted the folder and moved them back and it is the same issue. The received date for the emails is correct but if I display the received date in the columns of the message pane, after moving to a different folder, like the drafts it then resets the view. Removed the email account fully from thunderbird, restarted the app and setup the account again. Removed the account again, closed thunderbird, renamed the profile folder and MSF file for the account then setup the email again. Applied the view from a different set of folders that is not having the issue did not resolve the columns resetting or the date issue. I have reinstalled thunderbird, updated to the 95.0b version to ensure the version was not the problem. Any ideas on what might be a fix? Currently I have to make a change to the column selection to show received instead of Date anytime I look at a different folder in the email account as a work around.
