Mail attachments disappeared with Sierra

Woo-hoo! This seems to have worked for me. Cautiously optimistic. I received an email right after changing the settings and received both attachments that were included, a first since upgrading to Sierra.

Unfortunately doesn't work for me, still the same issue.

This setting only appears in my POP accounts. But only my IMAP account, an iCloud account, has the problem.

This tricks seems to work for me... I will keep monitoring during the next few days.

Many thanks if it is my solution!

Thanks so much for the suggestion. Unfortunately, I don't see any box for the "Automatically manage connection settings". The account this is happening on is IMAP. I see that box on a POP account, but the IMAP account is the one with this problem. Am I missing something? If so, I would truly appreciate any help.

I have precisely the same issue, but only on my MBP, not on my iMac (it has another issue with Mail - keeps flashing the outgoing message on the screen while sending - very, very annoying). Dragging the message to the desktop does nothing - the PDF is still missing. I just realized it was an issue for ME - that the senders had actually sent the PDFs. It seems to happen with PDFs more than other things. Small attachments do arrive. Mail lists 4 attachments for the most recent one - all small images. On my iMac, there are 5 - including the missing PDF, which I only realized was there after all when I switched computers. Definitely a bug that needs fixing. 😟

Could be a lead. Do you have any idea of what's different on the two Macs?

My experience of this bug is with images exported as jpegs from Aperture.

Good News and Bad News.

I've subscribed the beta tester program, only to send feedback on the various mail bugs, beeing curious i installed the Sierra 12.2.2 Beta 1 on a spare partition and lo! The intermittent apparent loss of attachment in outcoming messages ha disappeared, they stand where they were placed; before,if a moved a messages out of the imap directory in a local place the attachment seemed losted, moving back the message did not change anything, apparently, but either on the internet client or Ios mail the attachment were visible; so I think we are close to a solutions, one on the major issues will be corrected soon, i hope. For other people, they who are in trouble with s/mime, there is no change, the Beta does not make any difference, still need to drag the message on desktop. We must wait the new release. Another tip: don't install the Beta, in Preview.app there is a serious bug in PDF printing, on my HP laserjet produces bad graphics.

To speed up things I also sent a couple of feedbacks to Apple, do it, you can register in Beta program without install the beta.

Seems work to me too. Thx.

Hi ,

Open mail and its preferences , click on account information > click on drop down arrows of download attachments .

If you choose All : mail always download these attachments

Recent : mail always downloads these attachments within the past 15 months .

None : mail doesn't download any of these attachments .

So , change the settings from NONE to ALL or RECENT .

Open an email message that contains an attachment a message that contains an attachment has a paper clip icon to the right of the senders name in the message list .

If you don't see the attached files listed above the message body , click more ( on the far right ) .

Click the file you want to download to your machine , locate and open the attachment .

The file is downloaded to the location specified in your web browsers settings , with safari own Mac the default location is your 's download folder .

Note : This method is for IMAP account .

It does not solve this problem. It may help only if you had 'Download Attachments' set to none.

I concur with slaw425 - this doesn't work. I already had downloads set to "all" and I've changed it repeatedly to other settings hoping that it was a glitch, but no joy.

So far, nothing suggested has worked. Some attachments simply don't arrive on my MacBook Pro. I don't actually know yet if there are any that haven't arrived on my iMac, as could be the case - I may not have noticed if I was working on the MBP at the time.

Does anyone at apple read this?

I doubt otherwise there would be already a fix available.

This has been suggested before, and it doesn't work for me.
