Why is it necessary to Compress large PST files?

Being an Outlook user, you must be aware of Outlook PST file size limit. The maximum size of PST file varies according to the Outlook version you’re using. For e.g. if you’re using an older version, i.e. Outlook 97 to 2002, the maximum size of PST file is only 2 GB and it’s saved in ANSI format. On the other hand, if you’re using Outlook 2003 or any later version including latest Outlook 2016, the maximum size of PST file is between 20 to 50 GB and it’s saved in Unicode format. It’s completely fine if you’re using a Unicode PST file as you’re having enough space to store your mailbox. But if you’re using an old Outlook version, this might be a problem for you.

When your mailbox is reached to its maximum size, then it may cause some serious performance issues like PST files corruption and deterioration in the speed of your Outlook client. The problem doesn’t here. In fact, it becomes worse than before if the mailbox crosses its maximum size which is 2 GB. Though a Unicode PST file has enough size limitation, but still it’s not immune to such problems. Whenever a PST file is reached to its maximum size or crossed it, it can cause serious problems to Outlook users. In such situation, you must reduce PST file size in order to make it handy and smooth.
