“ This message cannot be displayed”

On my 3rd gen iPad Air, the Mail app has started displaying the error message:


This message cannot be displayed because of the way it is formatted. Ask the sender to send it again using a different format or email program.”


about one time in 10 messages. It has so far only happened in emails that I BBC’d myself. IOW, I am the sender. And I can see the first few words of the original email in the sidebar. So it’s a Mail glitch?


Any know the solution? Thanks.

iPad Air, iPadOS 14

Apple's Mail app has been buggy for quite a while now, actually. One other bug is that it keeps automatically fetching e-mails even when it is set to "Manually" in Settings.


Anyway, I noticed this "message cannot be displayed" issue as well, basically only on e-mails that I send to myself from my iPhone or iPad. The bug is still present in iOS / iPad OS 14.4.


When you send an e-mail to yourself via the Mail app, you essentially end up with 2 copies of this e-mail. One arrives into your "Inbox" folder and the other copy stays in your "Sent" folder. The Mail app doesn't seem to correctly switch between the two copies when tapping between them. This might be what is contributing to the randomness of the e-mail being "readable" or "bad".


Anyway, here's what I found out in my testing (it gets a bit complex):


After you send yourself an e-mail from the Mail app, whether the received e-mail is "readable" or "bad" depends on where you open it first.


1- If you tap on the e-mail in the Inbox folder first, it will be random (so it seems).

  • If it is "bad" in Inbox, the copy in Sent is also "bad". If you delete the copy in Sent, the one in Inbox will become "readable".
  • If it is "readable" in Inbox, the copy in Sent is also "readable". If you delete the copy in Sent, the one in Inbox remains "readable".


2- If you tap on the e-mail in the Sent folder first, it will always (so it seems) be "readable". If you then tap on it in the Inbox folder, it will be "readable" there as well.

  • If you delete it from Inbox, the copy in Sent will become "bad".
  • If you delete it from Sent, the copy in Inbox will remain "readable".


So basically the bottom line is this:


If you send an e-mail to yourself and it ends up showing "message cannot be displayed" when you open it in Inbox, go to the Sent folder and delete the copy in there. That should make the one in Inbox readable.

I just tried this and it didn't help. I'm getting the message "This message cannot be displayed because of the way it is formatted..." on every email I send from my new iPad Air 4 with the automatic bcc setting activated. This is happening to original emails as well as my replies to other incoming emails. However, my emails are being received by others, and the text is partially displayed in the preview panel.


The alert message advises me (as the sender) to "send it again using a different format or email program" but I don't see any relevant settings options in IOS that can be adjusted by the user. I also noted that at the bottom of the alert message it cryptically says "text/plain".


Grrr.

This worked for me

Here is an iPhone Email Tip that will hopefully save you some frustration:

When reading your email with your iPhone, have you ever got the following message?

"This message cannot be displayed because of the way it is formatted. Ask the sender to send it again using a different format or email program. Multipart/Alternative"

If this happens to you, you can work around the problem by first deleting your message. Then go find the message in your trash and move the message back to your in-box. You should now be able to read the message properly.

Apparently this was an issue with iOS 3. It was fixed in iOS 4. Unfortunately the bug seems to be back again in iOS 5.

Yes, me 2! I have been calling about this problem ever since iOS 14 came out. Thought it would be fixed in iOS 14 1 or 14.2, but is was not. They claim to NEVER have heard of this issue!! Not believing that! Happens randomly as someone said . Very annoying to put in Trash and move back which sometimes works and sometimes not. Sometimes I do it over and over. This is in my end only both in Sent mail and my blind copies. However recipient seems to get the email just fine. APPLE, PLEASE FIX THIS PROBLEM!! Happens on ALL IOS MAIL DEVICES.. iPhone , iPad!!!!!! Stop SAYING IT DOESN'T EXIST!!!!
