I am facing an issue with my Outlook — it won’t open because my PST file has grown too large. Every time I try to launch Outlook, it either freezes or throws an error message saying the file size has reached its limit. I have some important emails stored in that PST file, so I can’t afford to lose them. Can anyone suggest an effective way to fix this issue or reduce the PST file size without losing important data? Also, if there is any safe method or tool to split or compress a large PST file, please recommend it.
