The Error 1022 JET errDiskIO usually occurs due to disk input/output failure. So, whenever the Exchange Server requests for the database page but due to some reason the operating system is unable to get the access to that particular page and the error occurs.

This error can also occur if some incomplete transaction log set is being replayed in the database. For instance, if a transaction is running on log 9 but the transaction could not be completed because it might have exceeded the database size but after that, the page reference size has now been added to log 10. Because of this, it leads to the error 1022.
