There are lots of killer productivity apps out there, but you might be left out of the party if you work somewhere with strict IT policies.
It can be hard to convince your IT department to let you install Evernote or a Chrome app to help you get things done.
Here's how to stay productive with the tools you probably already have and sneak in some of your favourites.
UNLEASH THE POWER OF MICROSOFT OFFICE
If you work in the type of office where everything is locked down, odds are Microsoft Office is your company's productivity suite of choice, and Exchange is its preferred email platform.
That's not a bad thing! Microsoft Office is packed with features that can help you stay on top of your to-dos and keep your inbox organised.
They may not be as flashy as some other apps, but they get the job done.
Here are a few useful tools:
ONENOTE IS AN ORGANISING POWERHOUSE
OneNote is one of our favourite note-taking tools, and with good reason.
If you have a copy of Microsoft Office on your work computer, you might already have OneNote installed.
OneNote is great for quick notes, rapid outlining, to-do checklists and brainstorming.
It's surprisingly easy to learn, considering the rest of Office often hides some of its more powerful features in menus and checkboxes.
Unlock OneNote's Potential with Templates: Microsoft has dozens of OneNote templates that you can install (or take to work on a USB drive).
These daily calendar templates can help you get your arms around your schedule.
If you're not sure how to apply a template you've downloaded, this Microsoft article shows you how.
Many of Microsoft's best OneNote templates are showing their age (and were built for Office 2007 or earlier), but they still work well in later versions, and once you have them loaded you can tweak them to fit your specific needs.
If you're going back to basics with your note-taking techniques, some of these empty templates give you a blank slate you can use any way you choose.
Extend OneNote with Power Plugins: If you do have the option to install something on your work computer, consider the Clip to OneNote extension for Chrome, Firefox and Opera.
The add-in easily saves items from your browser right to OneNote.
Similarly, OneTastic is a powerful OneNote plugin that adds robust calendar templates, built-in macros that automate common tasks (such as search and replace, or resize all images), favourites and shortcuts.
It really extends OneNote's built-in capabilities, and it works with OneNote 2010 and 2013.
Capture Anything with OneNote, Not Just Text: OneNote natively supports images in notes, and you can create your own images or text annotations using the Draw tab.
If an image you use has text in it, right-click it and select "Select Text from Picture" to extract the text from it and make it editable.
If you prefer to speak to your computer, OneNote also supports multimedia notes, like audio recordings or video from your webcam.
You can even tag them and use the built-in search to find them among all of your other notes and notebooks.
If you have access to SkyDrive at work, you can sync your notes and notebooks with it, and access them anywhere on your phone or tablet.

BEND OUTLOOK TO YOUR WILL
Entire books have been written on how to optimise Outlook for productivity, but you don't have to read them to get the core message: Outlook is a tool you should use to be more productive, instead of letting it use you.
Don't jump every time it dings or obsessively check your inbox - tweak it so it works better for you and only notifies you when you're ready.
Use Outlook to Take Back Your Day: Some of our best productivity tips for handling your email and your calendar work really well with Outlook (and I say that from experience - I used them frequently at my last job).
For example, setting Outlook to check for email less often than the default gives you plenty of time to work and focus before the inbox rush comes. Ninety minutes is my taste; it's just long enough that I can get work done without missing anything big. Tell people to contact you through other means if it's urgent.
Tame your calendar by blocking off time to actually work, and then schedule your breaks and relaxation times so people won't book you end-to-end for meetings or conference calls. Any time you want to actually be doing something, put it on the calendar - that way others won't assume that because nothing's on your agenda, you're free.
Save Time Typing with Quick Parts: We've talked about how text expansion can save you hours of typing, but if you aren't allowed to install a text expansion program, Outlook's "Quick Parts" serves a similar purpose for emails.
If you ever find yourself repeating the same text over and over again in emails, you can save them as a Quick Part under the Insert tab (or menu).
Copy any selection of text and save it as a Quick Part to reuse in future messages. Then, add the Quick Parts button to your ribbon or toolbar to quickly add them to future messages.
Use Delayed Delivery to Send Messages on Your Terms: Delayed sending is another great feature built-in to Outlook.
Just click the Options tab in a new message window (or open the Option menu) and you'll see Delay Delivery.
It's perfect for when you want to schedule a message, retract a message before it actually sends, or you like answering emails at night but don't want to send them at 2am.
Customise Outlook Views and Make Old Messages More Searchable: Custom views give you visual cues to specific types of messages so you always see the important things first.
This old tip for changing the subject lines of old messages and these Outlook tweaks are just as good today as they ever were, although you may have to look a little for the same options under new menus or ribbon buttons.
If you can't get them to work, or you'd rather have a tool that does it for you, previously mentioned ToutApp is a combination web service and Outlook plug-in that's pretty powerful. Of course, you have to be able to install things for it to work, so there's that.
EMBRACE PORTABLE APPS
If you really miss your favourite apps, there may be a portable version you can drop on a USB key (or on your smartphone) and run without installing anything at all.
Some offices even restrict the use of USB ports and log attempts to connect USB devices, and some portable apps won't work on computers where the OS is locked down to approved apps, so make sure your company is OK with it before you give this a whirl.
We love portable apps.
You get a consistent experience across computers, no junk files left behind by an installation, and you don't have to run afoul of your IT admins, who would rather you not install anything (and certainly aren't about to give you admin rights to your PC).
If you don't like the idea of hunting for portable versions of your favourite apps, there are entire portable app suites you can download and load onto a USB drive with a few clicks.
Even if your favourite app doesn't seem to be available, do a little digging.
You may find an open-source clone that is portable, like Nevernote, a free, portable Linux-based Evernote client. It's not as elegant as Evernote's interface, but if you need access on the go, on a normally unsupported OS, or on a locked-down machine, any option is a good one.
SMARTPHONE: YOUR NEW BASE OF OPERATIONS
If Microsoft Office and whatever tools you get pre-installed just aren't cutting it for you, and portable apps aren't up your alley either, maybe the key is to make your smartphone or tablet your real productivity tool and stick to your computer for your actual work.
After all, all of the new and fancy to-do apps and tools are usually available for mobile devices, so instead of just letting your smartphone charge on your desk all day, turn it into a productivity tool.
Use it for your to-do list, or as a timer, or to notify you when a calendar appointment is about to begin.
If your phone's too small, consider a tablet. You have plenty of options, but an iPad or Nexus 7 will give you everything you need to be productive.
Regardless of the OS it runs, almost every tablet offers great battery life, the option to connect to a Bluetooth keyboard if you want one, and access to their respective app markets.
If your IT department doesn't like the idea of you connecting your own tablet to the company network or your computer, that's fine - make it a standalone device.
Tether it to your smartphone, or get a tablet with a mobile data plan if you need internet access at the office.
From there, you can work on your computer, and switch over to your tablet or smartphone when you want to update your to-do list app, fire up the app you use for note-taking, or update your calendars and alerts.

OFFLINE PRODUCTIVITY METHODS
Finally, you could always consider old-school, offline productivity methods. Many people still prefer paper, and a good notebook goes a long way towards staying organised and productive.
There are even productivity methods that cater specifically to paper journals.
If you can find a notebook that caters to your style of work - like a project planner or one with pockets for other documents, or even one that can be scanned and synchronised with an online service you use - it can make all the difference.
Plus, you can write in your notebook while you're at work, then sync when you're home, making sure everything is nicely backed up.
Similarly, consider productivity methods that don't need any special tools at all.
If a method like the Pomodoro Technique fits well with your workflow, you don't need apps or notebooks to make it work, all you need is a timer.
Don't be afraid to pick and choose methods that work given your situation.
If you can find a method that works well without apps or extra tools, or only requires a smartphone app, a whiteboard or some Post-it notes (Personal Kanban is a great example here), pen and paper, or fits nicely with something you do have access to, you're in good shape.
