Once the PST file gets corrupted it gets inaccessible and 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 PST file. Outlook doesn’t provide any tool or function to split the PST file but you can perform this by using “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 PST file.
