Outlook 2013 - corrupted attachments from .me account

I have exactly the same problem, with Thunderbird. Started slowly (occasionally) ~2 months ago and thought it was the Senders' fault. Has accelerated over past 2 wks & now every email with attachments has one or more of the attachments corrupted. I have 3 identities within Thunderbird - one POP & 2 IMAP. Two work fine; it is only the me.com IMAP identity that experiences this problem. Attachments are fine on my iPhone, so my work-around is to forward me.com email from my iPhone to one of my other 2 accounts, open the attachments there (in TBird), and then reply from me.com. But major hassle. I have scoured the internet looking for solutions, changed Config settings within TBird as recommended by some several years ago, etc. All to no avail. Hate having to give up iCloud & establish new identity, but no choice unless I can find a solution.

Well macinchat - it sure can't be Microsoft in my case. I'm using Thunderbird instead of Outlook, and problem happens with every inbound email to my me.com identity, whether from Gmail or iCloud (forward off my phone) or wherever... Microsoft nowhere to be seen.

I have the same issue with outlook 2013. Any pdf sent to my icloud account and accessed by outlook 2013 gets corrupted. When I access Icloud email over a web browser and look at the same email the attachment is fine and accessible.

I don't generally use Apple products, which is probably a good thing in this case 😁 Tried to solve this exact issue for my brother in law who is an apple fanatic for mobile devices but has Windows Desktops. Not impressed as I've re-installed and upgraded multiple versions of outlook to no avail. Files sent to his normal e-mail addresses are fine. Anything from his @me.com address with an attachment in the last few weeks .pdf .docx .jpg etc are truncated. Interestingly the older re-synchronised e-mail is fine so it maybe some sort of size limitation our friends at apple have added to the @me.com data being sent through the interface in the last few weeks ? Anyway he's pretty disillusioned too. ANY CHANCE OF A FIX OR AT LEAST AN ACKNOLEGEMENT OF THE PROBLEM ?

Thanks Macinchat. Can you elaborate on exactly what you did? Especially for those of us who do not use Outlook (Thunderbird instead).

My server name for me.com mail is mail.me.com (and port 993). Do these change to something else? Or does something else in settings change?

Tks !

Many thanks Macinchat. I have added "p03-imap." to the beginning of mail.me.com - and working fine so far. If I do not post again, it will be due to incoming attachments arriving OK. Too early to tell as yet. Tks

Hi macinchat,

I'm having the same problem. Outlook 2013 accessing my @me.com email. Was working fine but received attachments have been corrupted for the last week or so. I have tried changing to P03-imap.mail.me.com and also just imap.mail.me.com to no avail. How to I change to the @icloud.com server as you suggest?

Kind regards,

Cam

Thanks, macinchat. I tried setting the incoming server is set to p03-imap.mail.me.com (port 993) as you suggested and the regular email attachment that I have never been able to open now works great. Problem solved!

There is another much easier way to do things,

Close Outlook 2013

Delete the account from Outlook 2013 (Windows Control Panel/Mail/accounts)

Open iCloud control panel

Click on setup iCloud account

Wait (until it finishes the setup)

Open Outlook 2013
