I'm running Lion, connecting to an Exchange 2010 server. Sent messages are stored locally.

Once I've replied to a messages in my Inbox, the "replied" arrow appears to the left of the message, as normal. But when I click on the arrow to see the actual reply it fails roughly 50% of the time. By "fails" I mean that nothing comes up when I click. A message I sent minutes earlier/later can work just fine.

The reply WAS sent using Apple Mail (not my iPhone) and it IS in my sent mail folder. I have re-built my Spotlight index.

As far as I know, the issue is that Microsoft doesn't provide the Active Sync API to anything other than mobile devices. This is why using Exchange on Mac is a bit buggy.

I would recommend using Microsoft's own Outlook Web App (OWA) for your Exchange emails. Or installing the actual Outlook program for your computer. Those are what I use. :)

Those are probably your two best options if you need your email to be 100% reliable on your Mac.

I've experienced the same thing, but only with my company's Exchange server. My other IMAP servers (Gmail, MobileMe a private IMAP) all work fine, 100% of the time.

I'm pretty sure this is a server side Exchange bug.

  • Or possibly a confusion between server sided <sent items> and the local <sent> folder. Not sure. But we have 100's of Mac users converting to Lion/Exchange 2010 and this will be an issue – Frankns Aug 7 '11 at 18:50
  • i think it has to do with the general activity of the Exchange Server maybe the Server reaches it's limits. – konqui Jul 3 '14 at 5:38

I've seen the same behavior with IMAP accounts in Mail under Lion. I think it's a general bug, and not limited to Exchange (I say this because I have no Exchange accounts).

  • I saw something similar with Mail pre-lion, but completely re-building my accounts solved the problem. I'm wondering if Lion introduced the issue. – Frankns Aug 8 '11 at 0:29
