Outlook 2016 for Mac - search not working

Hard to say what that did, but from what I can see, that command has nothing to do with Spotlight. There isn't even an argument for -E. But then, it's hard to tell what this command does at all. The description is pretty darn vague. An Internet search turns up almost no information on this Terminal command.

Glad you're index is working, I just don't see how this command could have done anything to help.

MODULI(5) BSD File Formats Manual MODULI(5)
NAME
moduli -- Diffie-Hellman moduli
DESCRIPTION
The /etc/moduli file contains prime numbers and generators for use by sshd(8) in the Diffie-Hellman
Group Exchange key exchange method.
New moduli may be generated with ssh-keygen(1) using a two-step process. An initial candidate
generation pass, using ssh-keygen -G, calculates numbers that are likely to be useful. A second
primality testing pass, using ssh-keygen -T, provides a high degree of assurance that the numbers are
prime and are safe for use in Diffie-Hellman operations by sshd(8). This moduli format is used as the
output from each pass.
The file consists of newline-separated records, one per modulus, containing seven space-separated
fields. These fields are as follows:
timestamp The time that the modulus was last processed as YYYYMMDDHHMMSS.
type Decimal number specifying the internal structure of the prime modulus. Supported
types are:
0 Unknown, not tested.
2 "Safe" prime; (p-1)/2 is also prime.
4 Sophie Germain; 2p+1 is also prime.
Moduli candidates initially produced by ssh-keygen(1) are Sophie Germain primes
(type 4). Further primality testing with ssh-keygen(1) produces safe prime moduli
(type 2) that are ready for use in sshd(8). Other types are not used by OpenSSH.
tests Decimal number indicating the type of primality tests that the number has been sub-jected subjected
jected to represented as a bitmask of the following values:
0x00 Not tested.
0x01 Composite number - not prime.
0x02 Sieve of Eratosthenes.
0x04 Probabilistic Miller-Rabin primality tests.
The ssh-keygen(1) moduli candidate generation uses the Sieve of Eratosthenes (flag
0x02). Subsequent ssh-keygen(1) primality tests are Miller-Rabin tests (flag 0x04).
trials Decimal number indicating the number of primality trials that have been performed on
the modulus.
size Decimal number indicating the size of the prime in bits.
generator The recommended generator for use with this modulus (hexadecimal).
modulus The modulus itself in hexadecimal.
When performing Diffie-Hellman Group Exchange, sshd(8) first estimates the size of the modulus required
to produce enough Diffie-Hellman output to sufficiently key the selected symmetric cipher. sshd(8)
then randomly selects a modulus from /etc/moduli that best meets the size requirement.

I tried manyt of the suggestions on the web to get Outlook's search function working; rebuilt my Outlook database and Main Identity several times, forced Spotlight to reindex my HD using Terminal etc, but couldn't get it working.

Oddly, Spotlight and Apple Mail had no problems searching for emails, just Outlook that couldn't.

It was this suggestion that finally cured it for me: https://forums.macrumors.com/threads/outlook-2011-search-not-working-after-hd-sw ap.1316668/#post-16099768

After emptying my Inbox folder cache (right click on Inbox - Folder Permissions) it took a while to resynchronise with my Exchange server. However, the end result was Outlook's search function fully restored.

None of the solutions that I have seen from Apple and Microsoft worked for me (including re-indexing Spotlight and uninstalling and reinstalling Office entirely). But here is what did work: Microsoft recommends running the following command in Terminal to re-index Spotlight: mdimport -L . This failed for me repeatedly (I also tried re-indexing Spotlight using the System Preferences> Spotlight> Privacy on/off technique as well, did not work). What worked for me is running the Terminal command that completely ERASES and REBUILDS the Spotlight (rather than only re-indexing it): sudo moduli -E . This command took longer for my computer to process as it appeared to entirely rebuild the corrupted Spotlight index from the ground up rather than merely re-indexing a mess. Restarted computer afterward. Now Outlook and Spotlight are searching and finding my recent and emails dating back seven years for first time in a week. Hope it stays that way. Cheers.

Try Google searching: "sudo mdutil command". Produces a number of sites that describe the function of command sudo mdutil -E as erasing the Spotlight index and rebuilding it. For example: http://blog.shiraj.com/2014/01/terminal-commands-for-improving-spotlight-indexin g-volume/; http://osxdaily.com/2012/02/02/reindex-spotlight-from-the-command-line/ . I'm no expert, but it worked for me.

Yes, sudo mdutil -E would work. What you wrote above though was moduli, not mdutil. Moduli just happened to be another existing Terminal command. Hence the confusion of how it could have helped when I looked up moduli to see what it did. 🙂

Edit: In my prior post, autocorrect messed it up.

Autocorrect drive me nuts. I disable it on all my Macs. I'd rather have a misspelled word go through than have it change something to a word I didn't want, and don't notice it made the change.

Outlook Search Not working has become the most common issue which Outlook users faces nowadays. Let me tell you, this error has very simple fix.

Did you post the question in the MS community?

Since Outlook's arrival (replacing Entourage) in Office 2011, it relies on Spotlight to do any searching of its own database. Open the System Preference and click on the Spotlight icon, then the Privacy tab. Drag and drop your startup drive (where Office should also be located) from the desktop into the open window. Or add it using the plus button. Then highlight the drive and click the minus button. OS X will reindex the drive. When it's done (and as it's working), search in Outlook should work.

Since you have a MacBook Pro you very likely only have one internal disk. That is your startup disk since that is the disk you boot from. You want to reindex that disk. The default name is Macintosh HD.
