Picture this: you’ve got an old .ost file from a previous email account and you’re trying to wrangle it into Outlook 2019. You’re not alone; we’ve all been there, scratching our heads, wondering why these things can’t just be straightforward. The good news is, with a few steps, we can tame that wild mailbox item, turning it into a more manageable Personal Storage Table (.pst) file or simply accessing the information.

Now, .ost files, or Offline Outlook Data Files, are Microsoft Outlook’s way of taking a snapshot of our mailbox items, allowing us to work offline and then sync up once we’re back in the grid. But here’s the rub: these files don’t play nice when you’re trying to just pop them open in a new instance of Outlook—hence the need for a bit of know-how.
Let us be the magicians and convert the outdated .ost format to something that Outlook 2019 recognizes without breaking a sweat. And don’t worry, there won’t be any techy incantations involved; just a straightforward approach to get you back on track with your emails, appointments, and contacts faster than you can say “email alchemy.”

Setting Up Your Email Account in Outlook

Before we dive into the nitty-gritty, let’s get a handle on what Outlook profiles are and the role data files play in storing our mailbox information.
Understanding Profiles and Data Files
In Outlook, profiles are like individual workspaces that contain all of our email accounts and settings. Think of a profile as a dedicated desk in an office—it’s where you keep your work stuff organized your way. Now, every email you send or receive is stored in a data file on Outlook’s hard drive. Outlook uses two types of data files: PST (Personal Storage Table) and OST (Offline Storage Table). PST files are like your email library on your computer, and OST files are like a backup copy, allowing you to access your emails even when you’re not connected to the internet.
OST File: Specifically for Exchange and Office 365 accounts; it syncs with your mailbox on the server.
Configuring Mailbox with Your Email Accounts
How do we add our email accounts to Outlook 2019 and make sure everything is in tip-top shape? Easy!
- Open Outlook and go to the File tab. No muss, no fuss.
- We hit up Account Settings and select the Email tab. Here’s where the magic happens!
- We’re going to click on New… to add a new email account. This is like handing Outlook the keys to your mailbox.
- We’ll type in our email address, and Outlook is smart enough to figure out the server settings most of the time (talk about picking up what we’re putting down!).
- If Outlook gets a bit lost, we might have to enter the settings manually—but hey, that’s just an opportunity to show off our email setup chops.
- Once things are looking good, we’ll finish up and voila! Our emails should start coming through like letters in a mailbox.
Just remember, the OST file syncs with the server, so if there’s an issue with that connection, Outlook might give us the silent treatment until we sort it out. But don’t worry, we’ll deal with it if it comes up—it’s just part of the Outlook family shenanigans.
And there we have it! Setting up our email should be smooth sailing, but if the waters get choppy, we’ve got the know-how to navigate to calmer seas.
Importing and Exporting Mailbox Data
When it comes to managing your emails, sometimes you gotta shuffle things around. Whether you’re jumping ship to a new email client or just love to keep an archive, Outlook 2019’s Import/Export Wizard has your back. And if you’re thinking about mixing and mingling mailbox data between accounts or even other applications, I’ll walk you through it – it’s like giving your emails a tour of their new home!
Using the Import/Export Wizard
Kick things off by launching Outlook 2019 and mosey on down to the File tab. From there, a simple click on Open & Export, and Import/Export invites you to the wizard’s doorstep. Choose “Import from another program or file” if you’re bringing in the goods or “Export to a file” if you’re moving them out.
Looking to import some nostalgia from an older version, say Outlook 2016, or maybe from another program? No problemo, our wizard is a cross-generational, multi-software social butterfly! And hey, for those personal archives, the archive feature in MS Outlook can help tidy up your inbox while keeping your memories safe and snug.
Transferring Data Between Accounts or Applications
So, you’ve got yourself a brand-new email account and it’s as empty as a ghost town. Fret not—transferring data between accounts in Outlook is smoother than a jazz solo. And if you’re flirting with other applications, the wizard’s got some smooth moves for you too.
| Select File Type to Export | Choose the Destination | Finalize Settings |
| Pick .pst for Outlook Data Files | Go for the new account or application | Let the wizard work its magic! |
| Choose .csv for spreadsheets | Maybe a different email client? | Neatly map the fields if needed |
| Opt for .olm for Mac | Even to a whole different device! | Check the options, then take the leap |
We’ve all got different needs, but communication is key, and the Import/Export wizard is a universal translator for your mailbox data! Keep in mind, staying organized can be a game-changer, and we’re here to help you score big in the email game.
Managing Offline Access with OST Files
When we’re not connected to the internet, Outlook’s OST files are absolute lifesavers. They allow us to plow through our emails, calendar, and tasks without skipping a beat. Let’s unravel the mystery of these files and ensure our data’s tucked in safe for a rainy day.
Understanding the Offline Outlook Data File (OST)
Picture this: You’re off the grid, sipping coffee in a remote cabin, but your work mojo is still on fire. Thanks to Offline Outlook Data Files, or OST, us road warriors can access our Outlook items, hassle-free. OST files work like a charm, syncing all our work once we reconnect to the grid. It’s like having a work sidekick that’s got our backs.
Converting OST to PST for Data Backup
Now, here’s a nifty trick for keeping our emails snug as a bug in a rug: converting our OST to PST. Why, you ask? In case our data goes south or Microsoft Outlook decides to throw a tantrum, a PST backup is our golden ticket. It’s like an email time capsule, keeping everything from getting lost in the digital abyss.
We can use an OST to PST converter to transform that OST file into PST format, no sweat. This move is clutch when we need to backup or transfer data; or if corruption sneaks in, we’ve got a plan B.
| OST File | Action | PST File |
| Your offline Outlook buddy | Use an OST to PST converter | Your backup superhero |
| Can become corrupted | Convert | Safe and sound format |
Troubleshooting Common Issues and Recovery
When it comes to tackling the fickle nature of technology, let’s be real, Outlook 2019 is no exception. Handling an OST file can sometimes be as finicky as a cat in a room full of rocking chairs. So, let’s dive straight into the nitty-gritty of getting you out of the pickle when your OST files and Outlook aren’t seeing eye to eye.
Recovering Data from Corrupted Files
There’s nothing quite like the panic when you realize your OST file might be corrupted.
First off, relax. It’s not as dire as it seems. We’ve got a trusty tool called the Inbox Repair tool (ScanPST.exe), and here’s how to grab the reins:
- Make sure Outlook is closed. We definitely don’t want any more hiccups.
- Browse to the location of SCANPST.EXE, which you’ll normally find snuggled in the depths of your ‘Program Files’ folder.
- Run SCANPST.EXE and click on the ‘Browse’ button to locate your wayward OST file.
- Hit ‘Start’ and let the tool work its magic. If it spots something fishy, it’ll prompt you to initiate the repair process.
Remember, if the tool manages to fix your file, it’ll create a backup with a .bak extension. Keep it somewhere safe – like a treasure chest on a deserted island.
Tips for Dealing with Connectivity Issues
Ever tried whispering sweet nothings to your computer to improve connectivity? No? Just us? Well, here are some more, ahem, conventional tips:
- Go to the Control Panel and look for the ‘Mail’ option. We’re about to do some digging.
- Click on ‘Email Accounts’ and then the ‘Data Files’ tab.
| Step | Action | Result |
| 3 | Hit ‘Settings’ and navigate to the ‘Advanced’ tab | This is where the plot thickens |

And just like that, you’ve taken control of your connectivity woes. It’s not quite as satisfying as that “Eureka!” moment in a mad scientist’s lab, but hey, it’s close. Remember to toggle ‘Cached Exchange Mode’ back on once you’ve restored order in the email universe. It’s not just a checkbox; it’s your ticket back to smooth emailing.
