Oversized PST files are indeed a headache. Loyal Outlook users who have faced this dilemma from time to time will certainly vouch for it. In order to treat a headache, you need to know what is causing it and then you can take a step for remedy.
The very first question that is bound to strike your mind, “Why are oversized PST files a headache?”
The answer is simple! It's because Outlook PST files are imposed with a limitation on their size. The MS Outlook versions like Outlook 97, Outlook 2000 and Outlook 2002(XP) had a size limit of 2GB. Then came Outlook 2003 and 2007 which had a limitation of 20 GB. As time goes by, our needs subsequently increase. Therefore, the latest versions of MS Outlook had their size increased to 50 GB. Apparently, this too isn’t enough for its users.
Having a size more than the specified limit is one of the primary causes of file corruption. File corruption is a common phenomenon and also a prolonged one. This is one way to get your damaged PST files repaired. Working with oversized PST files on a regular basis will make your Outlook application slow. Thus, as the size of the PST files begins to increase, the performance of MS Outlooks is hampered considerably. And, there might even come a time when you might lose all your files completely.
Sounds like a nightmare, isn’t it?
The good thing is - you can solve the problem.
Now, you don’t want to lose any of your files and neither are you willing to accept Outlook’s degraded performance. What could be done in such a situation? Simple, you reach a middle ground by just splitting the oversized PST files. Voila! Just get on with it already.
