.OST Files Causes Outlook to Crash RRS feed

  • Question

  • I often get an error saying the .ost file is corrupt and I need to run SCANPST to make repairs. I'm connected to exchange using Outlook / Office 2007 Pro. I have a large email account in exchange so I believe the .ost file is justified growing to 3.2G. It's a laptop using Outlook in cached mode, since it's a laptop I can't turn off cache mode.  

    To fix the problem I delete the .ost file in the profile, when I open Outlook for the first time it acts as if its never been connected to the server and begins updating the email files and folders. Once updated works fine for a week or so.

    How do I determine what is causing the .ost file to corrupt.

  •  Hello Oliver,

    .OST file growing size is the one of the main reasons for corruption. I would recommend you to check the real size of your Exchange mailbox. If it exceeds 12 GB on server, then it is obvious that your .OST file will grow up to that size or even beyond, which can lead to noticable performance degradation and finally to corruption.

    You can try the following. Create a new offline file and monitor it's size growing. It takes time until your Exchange mailbox is fully in sync. Depending on size and bandwith it can take hours.

    If you find that too large file could be the issue, please read this article

  • Maybe the size of OST file is the reason for corruption. You can split OST file into smaller size. I dont know if there is any manual way to split OST file. You can also Google for same. But, I can suggest you some third party tools to Split or convert OST file to other file type.
