Yosemite Mail is unable to list search results.

I'm having the same problem? No search results in Mail. Blank. Empty. "No messages found".

It doesn't matter if the mailbox is still on the server (IMAP) or saved On My Mac in a mailbox folder. I tried a Mavericks fix . . . deleted all the files with name starting "envelope" from Users/"my name"/Library/Mail/V2/Data and then Mail reindexed all my messages, but then still cannot search messages within the Mail app afterwards. Spotlight search results do show mail, but I cannot search within the mail app.

If I can't fix soon I'll have to uninstall and go backwards to a time machine backup. I can't work without the ability to quickly search thousands of emails.

The same happened to me. In general Mail is not even able to show me anymore flagged items.

I tried to delete ALL folders and files in Library/Mail folder and reimport all accounts into the system. This helped but only for one day, so it looks like there's a bigger problem with mail, and it happens not only in case of migrating old emails into the new version of Mail.

I think this is quite crucial to many of users...

Yes indeed - see Mail Search & Smart Folder bugs in Mavericks still not fixed in Yosemite?! for my version of what looks like the same unfixed problem from Mavericks. Quite depressing.

That's quite interesting because I didn't have this bug at all in Maverick. For me it came just after installing the Yosemite upgrade. Did you try to install fresh system? I'm thinking about doing a backup of my data and then installing fresh version of Yosemite without any settings which could break the mail (so no use of TimeMachine either).

What haven't I done ... Yes, both in Mavericks and in Yosemite, I tried installing fresh versions of the OS, with the same result. After fresh-installing Yosemite, Mail worked the longest stretch it had worked in a long time -- about a day and a half. But as always, the problem recurred.

(My "canary in the coal mine" for the problem is a bunch of flagged messages, which show up in the Flagged smart mailbox when Mail is behaving. At the moment there should be 12 of them, and I can literally watch as the number icon next to the smart mailbox name goes down and down, until it disappears entirely when Mail finally thinks there are no flagged messages at all.)

Any of you reindexed Spotlight?

This is the “easy” method: Spotlight: How to re-index folders or volumes

However, sometimes that doesn’t work and you must erase the entire index in Terminal

sudo mdutil -E /

The sudo command will ask for an Admin password, but you won’t see it when you type.

The rest of it erases the Spotlight index on the startup volume.

It will automatically reindex once it is erased. You should likely do it at the end of the day to let it reindex depending on the size of your hard drive.

This will sometimes help for a while, as will a more limited reindexing of the relevant folder:

mdimport ~/Library/Mail/V2

-- in Terminal.

But the problem will probably recur in a matter of hours.

I’d nuke the entire index, not just subsets. It could be the index is corrupt.

However, with some of the other reports, I’m not sure that is it.

Hi all; Thanks for your replies.

piteer1: yes, the same with me, I didn't have it before, problem occurred after I upgraded from Mavericks to Yosemite.

I did wipe out the Spotlight index and reindexed using both the Apple recommended method and also the app Cocktail (which I'm guessing uses the "sudo" command). Both methods worked but restored mail searches using Spotlight or the Finder only. They did not restore searches within the Mail app. The only solution that has worked so far is to use Time Machine to restore my entire system back to Mavericks, but that defeats the whole purpose, doesn't it? That really isn't a Yosemite fix!

I broke my own golden rule: Never install a new version of OS X or iOS as soon as it's released. Always watch user comments for bugs and wait for the first update.

Same here. Spotlight completely blanking out with any search in Finder or Mail. Very frustrating.

Have people tried the re-indexing tip from Barney-15E?

For now this solution works for me also. I will wait with it a little more thought, cause deleting indexes for Mail was also working but for random period of time.

Hope this time this fix will be permanent. Thanks

What I did, with help from Apple tech support, and has helped a lot today with a number of issues:

1) Boot the machine is safe mode via Command-R

2) Run Disk Utility there

3) Repair Disk

4) Repair Disk Permissions (run 3 times)

5) Re-start

6) Let the system work at re-indexing files for a few hours

This has helped a lot with many issues

I have. It doesn't work.

I re-indexed twice yesterday and both times Finder searches worked for a few seconds afterwards.

Nothing works, I have tried repair disk in safe mode, repair permissions, delete envelope index files, reindex hard disk.

The only way to find the emails is through spotlight and it's very slow, an intolerable bug, I'm really really upset with Apple.
