Summary: Easy methods to split pst file safely into smaller easily manageable PST files manually using methods like yearly archive, move to folders, import-export, etc.
Microsoft Outlook stores emails and other mailbox items in a file named PST or Personal Storage Table. PST file is stored locally on the users’ systems. There are two kinds of PST files namely ANSI and UNICODE. Outlook 2002 and earlier versions use ANSI PST file which has a size limit of 2GB. Once the PST file exceeds this limit it becomes inaccessible and corrupt. The same issue comes with ANSI files (used in Outlook 2003 and later version) file when it reaches 50 GB. In this article, I will let you know how to split pst file safely.
Once the PST file gets corrupted it gets inaccessible and the user is not able to access his emails. You can avoid this situation by splitting the PST file into multiple PST files. You can also compress the PST file to reduce the size of the PST. Outlook doesn’t provide any tool or function to split PST file but you can perform this by using the “Import and Export” method or “Archive” method. There is another feature called “Move to Folder” which moves some content of PST file to another folder thus reducing the size of the PST file.
