ios – Apple Mail messages disappeared after IMAP deletion + native transfer failure (no disk house) – emlx recordsdata nonetheless exist however seem empty

I’m attempting to get better my Apple Mail inbox on macOS Yosemite (Mail v8) after a sequence of occasions precipitated all messages to vanish from the appliance, despite the fact that the uncooked recordsdata are nonetheless current on disk.

What occurred

1. The Inbox was by accident deleted on an iPhone, which eliminated the IMAP messages from the server.

2. On my MacBook (offline at that second), the emails have been nonetheless current regionally inside Apple Mail.

3. I attempted to maneuver the messages from the IMAP Inbox into a neighborhood “On My Mac” mailbox to save lots of them.

4. Throughout this transfer, the Mac ran out of disk house.

5. The transfer operation aborted, and afterwards the unique Inbox inside Apple Mail appeared fully empty.

6. Nevertheless, on the filesystem, the uncooked (emlx and Attachments) mail recordsdata nonetheless exist.

The place the recordsdata are positioned

The messages are saved in Apple Mail’s IMAP native cache at:

~/Library/Mail/V2//INBOX.mbox/

with a construction like:

INBOX.mbox/
 └── /
      └── Information/
           └── 0/
                └── 1/
                     ├── Messages/
                     └── Attachments/
                └── 2/
                └── 3/
                ... (many extra)

Inside these varied Messages folders there are literally thousands of:

*.emlx

*.emlxpart

*.partial.emlx

What I’m seeing

• Every .emlx file has a standard file dimension (for instance a number of KB or extra).

• However after I open them instantly on macOS, they seem empty in Apple Mail and present no message textual content.

• If I manually rename an .emlx file to .eml and open it on Home windows or in one other mail program, the message content material is totally seen.

• So the file content material remains to be there, Apple Mail simply refuses to show it.

Present state

• I now have loads of free disk house once more.

• I nonetheless have your complete authentic INBOX.mbox folder.

• Apple Mail refuses to indicate or rebuild the messages.

• Rebuilding the Mail index (Envelope Index* recordsdata) didn’t assist.

• The information clearly exists within the .emlx, however Apple Mail doesn’t see it.

My query

How can I restore the mailbox in order that Apple Mail acknowledges and shows the messages once more?
I wish to both:

1. rebuild the unique IMAP Inbox regionally in Apple Mail,

2. or recreate a sound native mailbox from the .emlx recordsdata,

3. or convert this construction into a correct .mbox file Apple Mail can import.

At this level I merely need a clear mailbox (native or mbox export) so I can later add the messages to the IMAP server once more.

Further notes

macOS: Yosemite

Mail.app model: 8

IMAP account

No Time Machine backup

Subject began after the disk ran out of house throughout a transfer from IMAP to native mailbox

The uncooked recordsdata nonetheless include the true message knowledge (verified by renaming to .eml)
