Can you VPN into your company's network, and access your mail messages via that VPN connection?
This looks like a problem with the MIME encoding for the message, and particularly something that Mail.app is sensitive to.
The VPN might avoid one of the potential triggers; something in your local network path.
Your best approach is probably to collect up some of the "corrupt" messages, and pass them along to Apple support.
I have the same problem on all my macs. That includes:
- MacBook Pro 17"
- MacBook Pro 13"
- MacBook 13"
I agree with you on all issues:
- this MUST be a Apple Mail issue for all reasons you describe (also that all attachment can perfectly be opened on all my iOS devices. 2x iPhone 4, 1x iPad1, 1x iPad2)
- the problem accures with many files types, but the ones that i know are: jpg, pdf, exel, word
- when it is a photo the photo is half loaded and you can see half the photo and the other half is grey
I think the problem comes from slow or irregular internet speed. Obviously that should not be an issue and isnt with any other mail program.
HOWEVER, I found a solution that works around this is a pretty easy way. Its still not solving it, but at LEAST i can get the mails attachments and work with them, rather than having to forward the mail from my iphone.
Basically 2 solutions: I prefer option 2, as it can be done fast and each time the issue happens.
- click the mailbox that has the issues
- go to Mailbox in the status and click "Rebuild"
- This will re-download all mails. its a bit overkill, but it works.
- create a new mailbox inside the main IMAP mailbox account
- move or copy the message with the broken attachment there
- now do option 1) only for this mailbox
- then move the repaired message back
Such a stupid issue!!!!!
- click the mailbox that has the issues
2 month later and several updates later this issue is still happening! It's not better rather worse.
I tried installing thunderbird and surely all attachments that weren't loaded in mail I could see.
Again they always load in my iPhone or iPad. Just not on my Mac. Or my wife's Mac. Or my partners Mac.
I hope to get some more feedback here.
Whatever happened to Fred? Was the issue solved.
Consider investing in somebody that can come in and look at the configuration in detail and troubleshoot this, or investing in and escalating this to Apple formally. Alternatively, see if an alternate mail server or an alternative mail client has the issues. This thread has been going on for a while after all, and this issue looks to be pernicious; I'd not expect this to be addressed here, and probably not without digging around with the clients and the configuration and the network(s) involved.
This is happening to me too, its terrible. SOME attachemnts are fine in Apple Mail but SOME show up as garbled text. I have to login to the GMail web interface to get them (because ther are fine there).
NOTE: when I first get an email in Mail it works OK... I move muy mail messages into another folder called Archive. Its usually when I want to go to an older message (which would be in Archive) that the attachment has this issue. I dont know if its related to moving into the Archive folder or because its older or some other reason.
Eitherway, the attachment is there and works fine in GMail so I think it an Apple Mail issue not reading it right.
I haven't really check here for a long while.... Seems like the issue is still there.
I am really disappointed with the Apple Mail, although there are updates everywhere just not in this issue.
The reason I didn't follow up here is because I kind of changed my mind and "not" using Apple Mail for a long while. Now I use Sparrow (I bought it from App Store) and it works just great.
Unless the attached file corruption thing is resolved, I can hardly go back to use Apple Mail ever.
Honestly, my iPhone/iPad can see all the images without any issue, but on both my MBP and two of the MBA I found the same issue. Don't know if anyone from Apple really cares about what we are taling about here?!
I hate rebuild the entire mail box, it will take forever to load my mails~ and usually it takes several times for me to rebuilt to get the messages correct...
