Learning how to find stuff in email is crucial, since many of us get so much that we let it accumulate until eventually it becomes a problem. Sifting through the many cc’ed work mails, or finding the order confirmation email in your personal mailbox amongst all the other stuff, we’re more reliant on search than ever.
This is a topic that has been covered numerous times in previous ToWs – 573 – Searching in Outlook and 504 – Searching Outlook for example – but is worthy of a revisit since we may have a chance to pursue the fallacy that is Inbox Zero over the next few weeks. And maybe it’s a time to find and delete the special offer emails and once-in-a-lifetime invitations that may be clogging up our personal mailboxes too.
Work mail
Dealing with desktop Outlook on the PC, there are plenty of tools available to help you find specific messages, in fact there’s a whole toolbar full of them.
As you look to search mail that meets your chosen criteria – it’s from someone in particular, maybe with a keyword in the subject, or that you know has an attached PowerPoint file, you’ll see that clicking the filters and options inserts the actual commands that will drive 
the search, into the Search bar positioned at the window’s top.
Remembering a few of these means it’s quick and easy to search for mail from a person (you don’t need the quotes, really, and you could use just a part of their name) by typing straight into the box. ALT+Q (for query?) sends your focus straight onto the search bar, so if you’re a keyboard warrior, you could ALT+TAB to Outlook, ALT+Q and enter a search command, before your 
mouse-toting colleagues have even clicked a toolbar. While we’re at it, remember that CTRL+number jumps to the location on the (now vertical) icon bar on the left, so CTRL+1 will normally be mailbox, CTRL+2 is calendar, CTRL+3 contacts, and so on.
Commands could also be used to filter on properties of a message that are not so easily visible through the UI – eg from:ewan messagesize:>10mb or from:nico sent:”last week”. See here for more examples of the kind of thing you can type. Look under Recent Searches to re-run ones you’ve typed before.
Reducing Mail Bloat
Is your mailbox size is starting to look under strain (look under the File menu to see how big your ‘box is and what the limit is)? With an active work mailbox in M365, it shouldn’t be much of a risk unless you genuinely never delete anything, but a quick way of identifying the big rocks and getting rid of them may be needed occasionally.
You could run a one-off search for all big mail as per the instructions above, or for extra control try creating a Search Folder. Expand the folder tree on Outlook’s left side, and scroll towards the bottom, to locate the Search Folders hierarchy, right-click on the top of the tree and choose New …
This will bring up a wizard which creates a query across your entire mailbox or other data file, but which looks like a folder; it’s visible only in Outlook desktop (ie not in web or on mobile) but can be a great way to locate stuff that might be filed away in the darker recesses of your mailbox.
You can choose from some set templates or do your own custom thing entirely. The age of this feature is somewhat given away by the default value for “Large mail”… click the Choose button and enter something meaningful (like 10000 for ~10MB).
This should give you a few easily deleted big mails to at least get any short-term capacity problems dealt with.
Right-click on the Search folder and choose Customize… to give it a better name, or to tweak the criteria.
Home email
If you have a Hotmail / Outlook.com etc mailbox, there may be a more pressing size issue, as over a period of years you might have been signed up to a newsletter every time you buy something online, and without realizing it, those could account for gigabytes of data bloat on your mailbox. If every notification from Amazon or eBay is 400K, they soon mount up to a meaningful size.
If you have a free Outlook.com account, you should have a 15GB mailbox quota and if you have the account associated to a Microsoft 365 home or work subscription, you’ll get 50GB.
To check, go into Settings and search for Storage.
The UI for Outlook.com is simple and effective, but one thing it doesn’t do a great job of is handling message sizes.
Sort by size and you’ll see a group heading showing which emails are 
the largest (displayed by default with the biggest on top), but nowhere can you find out what the actual message size is.
If you want to do a mass clean-out of your Outlook.com account, then you could try sorting by From, however the UI won’t let you click on the group heading to select all emails from that sender and make it easy to delete them.
The Windows Mail app on Win11 doesn’t offer Size either, not even to sort by.
Sometimes, the old ways are the best – you get much more functionality if you add your Outlook.com account to full-fat desktop Outlook, allowing you to change the view, see and sort by message sizes etc. Oh, and yes, you can even set up a Search Folder too. Now, tidy away!
This is the last “regular” Tip o’ the Week until January.
If you’re still here next Friday, look out for next week’s special edition – it’ll be a belter.
