When I tried repairing a damaged PST using SCANPST.exe, my windows used to get stuck. I had got quite frustrated as even after trying multiple third-party tools and even Microsoft’s own SCANPST.EXE, I was not able to resolve “Cyclic Redundancy Check Error“.
After reading your blog post I tried repairing my Outlook email file using Stellar PST Repair tool, I was able to view all the emails in it. I’m glad that I bought the software as my Outlook Client is working perfectly again.
Our team had fixed this issue through ScanPST.exe but lost around 70% mailbox emails. Then, we approached an Outlook MVP to work around this problem. He helped us to get back all lost emails through the help of Stellar PST Repair.
But, I have this error on Windows 10 PC with Outlook 2016 email application. I need archive file of Outlook 2016 mailbox in Office 365 suite.
Is it feasible with the only ScanPST.exe? I also need the support of Office 365 also.
Hi Minnie,
As per opinion of MS Outlook experts, ScanPST.exe does not provide the output with 100% accuracy.
Please elaborate your purpose for office 365 environment.
