Posted by Nancy ahuja

The errors on your OST files may prevent it from getting synchronized to the Exchange Server. Corrupt OST files may report missing items from the mailbox once after synchronization is completed which means OST files doesn’t completely synchronizes, however it is only partially synchronized which really doesn’t serves your purpose. Therefore, you would want either to create a fresh file which is error free or may want to repair the existing file that has gone corrupted. Of course, later is the right decision rather than going about to create an entirely fresh file which may take a great amount of time and effort. Also, this is not just because the OST files contain all types of mail data and you can’t even create some on your own.
