Hi all,

one of our users is getting the error when outlook is opened that the .ost file is corrupted. Curiously not always happens when the outlook is opened but it happens a lot of times. We have tried to remove/rename the ost file with the purpose of recreating it again as we need that this user works in cache mode. After doing that the ost file was re-created and everything seemed fine. However the issue come back again appearing exactly the same message.

I could read in one post that after renaming the existing one, it would be interesting in doing a chksdk /r just in case of bad sector. Later recreate again the ost file.

Do you know or would you know something more which we would need to keep in mind or taking care of it?

Thanks

it could be bad sectors, but windows should skip it when writing the new data file.

Are you using any software that interacts with outlook? If it keeps the ost open when you close outlook, the ost can be corrupted.

Is your antivirus software scanning the ost? (If so, turn that feature off.)

Converting the ost to a pst is not going to help when the user has an active Exchange account.... and scanost only fixes the problem (same as deleting the ost) - it doesn't nothing to address the reason why it's getting corrupted.
