Why do you need Stellar Repair for Outlook?

Outlook PST files grow in size and often reach several GBs, due to reasons like disabled auto-archival settings and user’s ignorance. Sometimes even after enabling auto-archival, a sizable chunk of messages in the PST files may not be archived due to an unexpected lapse in the Outlook archiving methodology. Such overgrown PSTs are prone to corruption– hence resulting in mailbox data loss, and also affect Outlook performance. Microsoft Outlook inbuilt utility- ScanPST.exe repairs Outlook data files but has a few limitations. The utility cannot repair oversized, severely corrupt or encrypted PST files, and might not help Outlook performance issues. Stellar Repair for Outlook is a great alternative to Inbox Repair Tool, as software serves as a complete recovery solution to fix Outlook corruption.
