Tips to Break or Divide an Oversized Outlook PST File into Multiple Parts

As per the common observation, the performance of MS Outlook starts degrading gradually as the size of the PST file tends to grow. This could sometimes result in complete inaccessibility of Outlook if attention is not paid or proper measures are not taken. Basically, this happens due to the file size limit of PST in Outlook, which is mere 2 GB in MS Outlook versions 97, 2000 and 2002 (XP); 20 GB in MS Outlook 2003 and 2007 versions. However, in the latest versions i.e. MS Outlook 2010 and 2013 this limit is considerably increased to 50 GB. 
Maximum problems are faced in the earlier versions due to very less size of PST. Avery simple solution to avoid this problem is splitting the PST file. It can be easily performed by moving the data items of the PST file to another PST or location with the help of the options that are available in MS Outlook itself. Firstly, you can simply move the PST file data items to other folders by using the option ‘Move to Folders’. Secondly, you can archive the data items that are not being used by using ‘Archive’ option. Thirdly, use ‘Import and Export’ option to send or receive the data items from one PST file to another.
We will go through the complete process of all the three methods by following which you can easily move the PST file data items and split the file yourself.

All the aforementioned options of splitting the PST file i.e. Move to folders, Archive, Import and Export are available in MS Outlook itself. These can be used by the user to manually move the data items contained within the PST file to another location so as to reduce its size. Although these methods are quite useful but a user who does not have knowledge about the technical criticalities might find difficulty in performing them or a busy administrator might not find out ample time to do them. In such a case, a user-friendly commercial tool to split the PST file does the needful.
