How to Amalgamate PST files Safely

So far we have read about what happens if your Outlook PST file minimum size limit is exceeded and the measures to prevent PST corruption. If the corruption has already taken place, you can recover from it using PST Repair Tool by Microsoft. There is a concern that many people have and shared with me. They say that it is not possible for them to manage multiple PST files and amalgamate PST files in order to prevent corruption of PST file because of its size limit. A nice question asked by a curious 1st year college student was:

PST CompressQ: Is there any way that we can Amalgamate PST files?

First I recommend you to verify which version of Outlook PST is there in your computer. All information about PST is mentioned on Wikipedia.

So here i am with a solution of how you can amalgamate PST files to save disk space and keep Outlook working without any bug. Previously i had shared a solution to combine or merge multiple PST files into a single PST and it was really effective. You can create space or compress your Outlook PST file in multiple ways, i.e. manually or a third party effective tool. I am sharing a manual technique which can be effective at an extent, but if your Outlook PST is very large, then I recommend PST Compress and Compact tool which gives multiple options at the time of compression and safely compresses your Outlook PST.

You can compress the PST file by managing the mailbox items, using Mailbox Cleanup tool which comes with MS Outlook.

Your PST files will be now compressed and with a reduced size. Though these manual techniques work well in small scenarios, but when it comes to large and important file transfers daily, you cannot afford deleting a single file. In such cases third party tools are the best options to go with.
