Merge option will merge various folders of similar name across multiple PST files which lie on same hierarchical level. A simple example will help you to understand it. Suppose you have taken a backup of your drive and kept it at safe place and keep adding more new files in that folder. And after few years, you look for some files and get confused, so you can sort out this confusion with merge operation.

Simply copy drive’s folders from backup and paste in current folder,so that now you have the exact same folders hierarchy which was earlier plus new root or sub folders also in the drive. This is known as merge operations.

The JOIN operation is somehow different as here you have multiple root folders generated to accommodate new child folders from separate PST files.

Merge contacts is simple as it seems, it simply merges all the contacts exists in various PST files. This operation is quite handy when you have your contact lists regularly inflamed over a long period of time. Merging all contacts in one PST helps you keep all contacts at one place. It’s one of best tactics professional users in an organization are blessed with; correct me if I am wrong.

The Remove duplicate option is rather useful in merging PST files and merge contact operation then in join PST operation for obvious reasons. But it’s really an awesome feature which surpasses all other features. Although it’s not emphasized in the software, but as we know that companies like Microsoft has a habit to conceal its most useful and tricky features. This teeny tiny check button is my favourite amongst all and I regularly love to check it and let this beast running. Anyways, enough of boring humour and let’s get back to the topic.

The Exclude deleted items option is pretty straight forward too. You can check this to exclude deleted items folder in all selected PST files. Another obvious reason as deleted folder does not find path in generated PST file and bloats it again. I want my merged PST file be compact and solid, no extra mail items.

Few other settings which are not so complex are merged PST file path and its name. You can change it accordingly by checking your available disk space. A rule of thumb is to choose directly where free space is greater than all PST files combined[to be on safe side], so combining PST operation does not complaint in middle. And I am sure that you will not like that nasty red message in log Window as disk space is low: operation aborted. If you are really space crunched, then you can use following formula to calculate free space:

{[total PST file size] x 30}  / 100 = required free space

You can optionally choose to list or attach generated PST file in MS Outlook, so you need not to seek the generated PST file in your system and perform so many steps to get your PST file listed in MS Outlook.

Suggestion Type password in case you want your merged PST file to be password protected.

Now you have understand all the GUI portion, so now press process and you will notice a log window with various emails which are listing and processed by the PST Merge tool. Once the process is completed, it will pop a message saying that merging process is finished and you can check merged PST in MS Outlook.
