10GB+ PST leading to Outlook performance problems: Need Help
#1
I am currently facing serious performance issues in Outlook because my PST file has grown over 10GB. Outlook is frequently freezing, taking too long to open emails, and sometimes even stops responding completely. What is the safest and most effective way to fix performance issues caused by an oversized PST file? Are there any recommended tools or methods to reduce the file size without risking data loss?
