Summary: Problems in locating OST file are not uncommon in Outlook. One day you can be working with a perfectly running Outlook instance; a slight modification to the default settings and you could be looking at a message as cryptic as “Outlook cannot find OST file”. The best remedy thus is not to mess with default Outlook settings. But if you need to make changes and also get rid of errors, converting your Outlook OST to PST format with a reliable tool like Stellar OST to PST Converter can come in handy.
Microsoft Outlook saves user mailbox data in local data files on the system where it is installed. If configured with a POP mailing server, the data file is known as a Personal Storage Table (PST) file; if configured with Exchange, the data file is known as an Offline Storage Table (OST) file. In addition to this slight difference, there are other larger factors which differentiate OST and PST files. OST files, for instance, are system dependent while PST files can be moved from one machine to another. This variation makes the usage of PST files more preferable as compared to OSTs among users. Just one of the reasons that prompt users to convert their Outlook OST files to PST format.
While there are several other situations demanding such a conversion, this post discusses a unique and classic example of the problem which the default setting of OST files creates. It brings out why sometimes it becomes almost necessary to convert OST files to PST format to solve an issue at hand. Let us see what the case is and if needed, what is the best way users can convert their Outlook OST files to PST format.
We recently came across a problem scenario wherein a user wanted to change the default location of his Outlook OST file for some professional reasons. While doing this with PSTs is relatively straightforward, in the case of OSTs matters tend to get a little tricky.
The user tried changing the OST file location by altering the registry entry for his current Outlook profile, but it didn’t work. Instead, he ended up with a “cannot find OST file” error. What he did was that he created a new Outlook profile and then located Outlook registry entries in Windows registry at:
Here inside the PROFILENAME key, he entered the path of the system directory where he wished that his Outlook OST file be saved. But after making this change when he restarted Outlook, he received the error:
“Not a valid path. Outlook cannot find OST file”
The problem with this approach was that the user failed to acknowledge fact that an OST file is tightly coupled to the Outlook profile with which it is created and therefore it is also tied to the default system location mentioned in the registry. To change the default location you’d need to be a tech-whiz and execute scripts full of PowerShell commands which will alter the very nature of your Outlook installation. But after doing that, you’d have to be prepared for the worst: either your Outlook will stop working all together, or your OST file will become corrupt and you’ll end up with data loss.
A better way to deal with the issue, thus, would be to not mess with the default OST file settings at all, but instead, convert the OST to PST format and then transfer it to whichever location needed. That way you’d preserve your system settings, not waste hours working on futile efforts, and also protect your OST file from inadvertent damage.
Now coming to the main question here – how would you go about converting OST to PST?
