Once upon a time, users had to deal with email quotas that meant they often had to shuffle messages around to stay within their allowed size limit, or else get limited functionality. The Outlook Thread Compressor tool* was written to help reduce the size of a user’s mailbox, and for a while, had thousands of users inside Microsoft. It inspired the Outlook team to write the “Conversation Clean Up” feature, which works in a slightly different way but does similar things.
Nowadays, with 50 or 100GB mailbox quotas being the norm, most Outlook users don’t need to worry about reducing the size of their mailbox other than to keep it from being too hard to use – a tidy mind and all that. But if you have massive mailboxes, the storage and organisation of all your content may put an unnecessary strain on your PC, so it’s worth taking a few steps to check and clean up if you can.
In Outlook 2016, go to the File menu and look for Tools > Mailbox Cleanup for a bunch of tools that can help, including being able to view your current mailbox size…
… and marvel at a dialog box that hasn’t changed since the earliest days of Outlook, evidenced by the fact it measures size in KB rather than MB or even GB…
Limits to be aware of
There are some recommended limits that have been given to Exchange/Outlook users over the years – not just about the overall size of the mailbox, but the number of items in certain folders and even the number of folders themselves. See a 2005 post on the Exchange blog here, for example, which advises keeping the item count low on certain folders (< 1,000 items in the Inbox, Calendar and Contacts folder was the recommendation then – also on the Exchange Blog, check out some of the examples in this post for early pioneers of huge mailboxes).
In more recent versions of Outlook, though, there are some guidelines to avoid performance problems:
Now, you’re probably not going to have too many folders with more than 100k items though it might be worth checking Sent Items and Deleted Items. Unfortunately, the mailbox size tool above shows you the total size of each folder, rather than the number of items – and if you want to know how many folder you have, you’d need to manually count them in the scrolling list box: not an easy task if you have lots of them.
It’s quite possible if you’ve had your mailbox for a while, and you’re a very diligent filer (especially if you use a methodology like GTD or tools like ClearContext), you could inadvertently have more than 500 folders – and if you use AutoArchive, then you could find a lot of them are empty, since the archive process moves the items out into another location but leaves the folder structure behind.
FolderCount to the rescue
Here’s an interesting little hobby project – a macro-enabled Excel sheet which cycles through all the folders in your mailbox, tells you how many items are in each one and offers to get rid of the empty ones for you.
It can be run in:
Use with caution; though anything that is successfully “deleted” will be moved to Deleted Items first, therefore you’ll need to run it again to actually do the damage (or just empty your Deleted Items… a thought that fills some people with dread).
To run it, click on the link above, save the file locally, open it up in Excel and you’ll need to enable the Macros to run – probably by first enabling editing, and then allowing macros by “Enable Content”.
Once you’ve done that, click on the appropriate button to let it run. I’d suggest starting with the top one until you feel brave…
*The Thread Compressor tool was made available externally after a time, but the domain disappeared… the actual Outlook Addin is again available here, but you’re a bit on your own as far as installing and using it is concerned…
Month: September 2018
Tip o’ the Week 447 – October is usually boring
October is – in the northern hemisphere at least – a generally pretty unexciting month. The early blaze of autumnal foliage settles into a muted rusty colour before falling away; everyone’s used up their vacation allowance so the roads are clogged with traffic just as the weather starts to worsen and the mornings and evenings get dark. Kids are bored, and folkin’ folkster Roy Harper tells us we do nothing but coagulate.
If you get excited about updates to your computer’s operating system, however, October is going to be a bit more interesting, as the next release of Windows – hitherto known as Redstone 5 – will be with us. Read more from MJF, and see a good summary of what’s coming, here.
There are lots of user interface changes, tweaks and improvements. If you like “dark mode” in apps, it’s getting more pervasive. Windows Weekly talks about the momentum behind Windows 10 if you have a spare hour-and-a-half to listen.
There’s a great new cloud-oriented clipboard experience that can be enabled (it’s off by default, so no need to get spooked), and there will be an improved screen snipping capability – both examples of the kinds of supposedly small improvements which can make a big difference to anyone with more than one PC. And both of these are features that have been proven using “Garage” projects in the past.
The Your Phone app discussed in ToW 442 will be available to all, too. The much-anticipated “Sets” feature isn’t coming this time, though.
So keep ‘em peeled over the next few weeks, for the appearance of the October update. Maybe more news will come at Ignite.
Tip o’ the Week 446 – What’s brown and sticky?
Q: What *is* brown and sticky?
A: A stick…
Q: What’s yellow and sticky?
Yes, the Post-It note (which has gone on to spawn many imitators, sometimes known as just “stickies” or “sticky notes”) was essentially invented by accident almost 50 years ago, by a scientist at 3M who was trying to make a super-strong glue but instead came up with one that didn’t really stick very well but was at least reusable and didn’t leave any residue behind.
Of course, the real story is a lot less simple – the product really took more than a decade to perfect, and convincing people that it was a viable business took several attempts, but eventually it went on to be one of the most-bought office supplies in history.
The digital equivalent has had decades of evolution too, from a simple note app from the company that brought you Tiny Elvis to the Sticky Notes application that shipped with Windows 7, and innumerable similar apps in the various mobile and desktop app stores.
Starting with the Windows Insider “Skip Ahead” community (but soon to roll out wider), the Microsoft Sticky Notes app has been heavily revised, consolidating the multiple windows that would typically be left on your desktop with a single list, and then pop-out notes that feature multiple colours, support for ink, cross-device syncing and more.
Keep an eye out for the Sticky Notes 3.0 arrival on your PC. As MJF says, with the same team now responsible for OneNote, To-Do/Wunderlist, and Sticky Notes, it’ll be interesting to see how deeply integrated they get.
