In this post, I will show you on how to use search in outlook to find emails properly. We will learn on how to narrow your search criteria for better searches in Outlook. You can use Outlook search for words in attachments, search by email size, by date and a lot more.
One of the problems I have with Outlook is the time I spend looking for stuff in the past, I use a multilevel folder structure to archive emails that I wanted to keep but I realized organizing it, like in the old days, like a filing cabinet with lots of different drawers is not how it looks should be used then I started to use certain outlook, but it didn’t work the way I wanted it to. I’d get hundreds of results back, which I try to visually filter. You can imagine the frustration there. At some point. I realize there is much more to search than just dropping a word in the search box and pressing enter. He can actually find exactly what you want. You just have to know on how to ask it the right way.
How to Use Search in Outlook?
- Microsoft updated the search functionality in 2019 for Office 365. The search is now faster and the search for itself was moved to the very top of outlook to the title bar. This is now the same for the desktop app and outlook for the Web to use search.

- Just click inside the search with your mouse or use the shortcut key Alt + Q or Control + E. This will open a dropdown where Outlook will make some personalized suggestions based on your recent activity.
- I don’t find that particularly helpful, but in case you want to repeat a search, this may be useful for you.
- In the past, I typed my search words and get hundreds of results back but that’s like driving your car in first gear only. It’s going to take forever to get anywhere.
- There are two ways you can use search, instant search and advance search. I’m going to show you both.
Instant Search in Microsoft Outlook
Let’s start with instant search. Let’s say I am looking for something with the keyword test I just type it in the search box, press, enter and get all results. To narrow down the results, I can go to the search tab with additional buttons.

I can refine my search step by step. You can narrow or expand the scope of your search. You can find the below fields.
- Current Mailbox – The default is mailbox. I’m going to show you later on how you can change your default if you need to.
- All Mailboxes – If you have more accounts, you may want to expand your search to all mailboxes.
- Current Folder – Another option to restrict your search is to narrow it down to just the current folder. This means inbox excluding sub folders.
- Subfolders – If you select sub folders, you include inbox and every folder below it.
- All Outlook Items – All outlook items is as broad as you can get. It’s going to search in all mailboxes and not just in mail, but also in your calendar and contacts.
- Include Deleted Items – Under results, you get the option to include deleted items in your search. Depending on your situation, this could really inflate your results so I don’t recommend that. Instead, you can always search the deleted items folder separately.
- Include Older Results – If your search does it return what you were looking for, you can select include older results.
- From – Your search may take longer this way, you get to really narrow down your search results. The message I’m looking for was for me. I can click on from and type the sender name and hit enter this way. It searches for everything with the keyword Excel plus where the user is the sender.
- Subject – I can click on subject and add that to my search.
- Has Attachments – I know that the message had an attachment so I select has attachments and maybe I also know that the word course was included in the subject line.
- Categorized – If you categorize your emails, you can restrict the results to a certain category with this dropdown or would send to you get to search by recipients.
- Flagged – You can search for mail that you flagged
- Important – You can search for mail that you marked as important. These options were really help you find what you’re looking for.
Advanced Search in Microsoft Outlook
- The second method is to use advanced search. Now, this is a more efficient way and it’s going to give you even more options instead of sequentially narrowing down the search like we did in instant search. You can do it all in one.
- To get it, click inside the search box and then click the dropdown which will open a dropdown with predefined search fields.

- You can define where to search in if what you’re looking for has an attachment or not.
- Basically, all the search options we saw on the search tab you can also find here and you even have more choices. For example, with attachment contains, you can directly look for keywords that you know are in the attachment of the message.
- Let’s say, I know that the message I’m looking for had an attachment that contains the word Set 1. I put it in quotation marks because I want an exact phrase match. We will cover search syntax towards at the end of the article, so stay with me.

- That’s pretty cool. Also, you’re not limited to the predefined search fields that we saw in the dropdown. Let’s go back to advanced search and notice the button that had more options in the corner.

- We get to the advanced search options where we can enable additional search fields. Let’s say I want the option to specifically search for recipients in BCC, check the BCC box and click on apply. Now we have become available for search. Remember these additional options. Whenever you can’t find the fields, you need to restrict your results to now.

Settings and Indexing for Search in Outlook
- Let’s talk about options and indexing. As always, with office products, there are some standard application options we should explore.
- Go to file and select options and then select search. Under results, you can define a default folder for the instant search. The second option, you can choose to include deleted items when you’re searching in all items. Typically, I don’t enable that. You can also change the highlight color. That’s the color used to highlight the search terms in the results on top.

- We also have indexing options. This is an important topic when it comes to search. Indexing helps you get faster search results.
- It’s not just relevant for outlook search, but any search that you’re doing in Windows, essentially indexing is going through your files, your messages and any other content in your PC. It’s cataloging the information.
- When Outlook’s search doesn’t find what you’re looking for or it just gives you incomplete results, indexing is not working properly.

- There is a lot more on indexing but two important things to remember. When we click on indexing options, you will get the current status, make sure that indexing is complete. Number two, make sure that outlook is included as part of indexing. Under index these locations, you should see Microsoft Outlook. If not, choose modify and click to enable it as a last resort.

- If you’re still having trouble with accurate search results or indexing doesn’t finish, you may have to rebuild the search catalog. This will restart indexing of your data files.
Outlook Search Syntax and Operators
- Finally, let’s talk about search syntax. Now that we understand the technicalities of outlook search. Let’s cover some basics about search syntax.
- Outlook search uses prefix matching. If you type plus in the search box, it will find messages that contain plus pluses and plushie, but not excel plus or surplus. Also, it’s not case sensitive, so it will find plus in proper case and plus in other cases.

- Well, we already saw that if you want to look for an exact phrase like set 1, you need to put it in quotation marks. If you don’t, it will return all variations.
- You can also use logical operators like, and, or and not in your search but you need to use uppercase letters. For example, if you search for Leelah and Garani, it will return items containing both Lillah and Karijini, but not necessarily. In that order, Lillah or Garani will find items containing Lailah, Leyla’s Garani or any other combination of uppercase and lowercase letters. Lillah not Kirani will find all items with Lillah that don’t include the word Garani.

- You can even use comparison operators like greater than or smaller than size. For instance, if you type message size, then put a colon and then the greater than sign 5 MB in the search box. It will return items that are larger than five megabytes.

- Pretty cool, right? If I use the syntax received greater than let’s put in February 6th 2021, it will return all emails received after February 6th, 2021.
