Dear customer: The error thrown in this 1025 translates to MAPI_E_CORRUPT_DATA. This event is usually not an indication of serious corruption in a database. It does however point out that some pointers are not valid within the store. The error is not ignorable. This issue is caused by the database error and running ISINTEG fix test should resolve the issue. Additionally, please check whether you install AV on your Exchange server, if so, Here are a couple of articles on Exchange Server and AV software.
