My company has just transitioned from an IMAP provider to a Microsoft Exchange server. As part of the transition, I moved all of my old messages from the various IMAP folders into corresponding folders on the Exchange server.
They've moved, but some of the message are showing the wrong date in the Apple Mail list views. The date is still correct in the message itself, but all of the timestamps in the list view are showing the date and time that I moved the messages, not when they were created. From some Google searches, it looks like it's the "date received" that's now wrong in the messages, and that's what the list views use.
What's weird is that it didn't do this to all of my messages - just some of them. It does look like it did it to all of the messages that were in my old IMAP "sent" folder.
How can I fix this? The messages are now in scrambled order in the list view, rather than showing in the correct (date sent/created) order - but even if I could fix the sort order, it's annoying that the timestamp has been replaced with the time it was moved into the Exchange server. I want the "received date" to go back to the date it was actually received, or if that's now impossible, I'd like to set it to the same timestamp that's in the message itself. Or, worst case, if I need to just restore all my messages from a Time Machine backup, how do I prevent this from happening the next time I try to copy these to the Exchange server?
Please note that this is not a fix, you're just changing the view from Received to Sent. The issue is that the received date is being modified because the server treats the copied/moved/migrated emails as being "received" there and then. This causes havoc for mobile users whose email programs can sorts emails by any way other than received. – Guy – 2018-08-29T12:15:06.070
That does fix my problem of having them in the wrong order, which I appreciate, but Mail still shows the "date received" in the actual column view which makes it very difficult to find things. I'd still like a way to replace what Exchange sees as the date received with what's obviously still stored as the date sent. Thanks for this though. – Charles – 2012-05-02T00:39:55.923
Actually -- once I also updated the View -> Message Attributes to include "Date Sent," it changed all of the dates in the column view to the date that I want once I clicked onto a different folder and back again. I'm not sure why it shows two dates selected in the Message Attributes menu, since it's still only showing me one, but at least it's the right one now. Great! – Charles – 2012-05-02T00:43:22.487
