TRC Data Recovery can retrieve data from damaged, unmountable or inaccessible Exchange server databases. In many cases we can recover the database to a working state and return this to you; failing that we can retrieve individual mailboxes and export them to PST files for simple re-integration.
TRC recommend that prior to running any Microsoft repair utilities (such as ESEUTIL), that a full backup of the Exchange database be carried out. Standard utilities can make matters worse in the event of the server's storage failing or serious corruption within the Exchange database itself.
By backing up your data before attempting a repair any storage medium errors, such as bad sectors, will become apparent. Should this happen a professional data recovery service will be required.
Some of the Exchange problems that we can successfully recover from are detailed below:
In versions of Exchange that are limited to 16GB information stores limits can quickly be reached. In the event of an unmountable Exchange EDB file and where attempts to Exmerge or access the data have failed, we can help. Once again, caution should be taken to backup the database prior to attempting any repairs or using any utilities.
Many different JET related issues can cause loss of access to your Exchange database. One of the more common errors is found when running ESEUTIL.exe:
JET_errRecordNotFound, the key was not found
This is a problem that Microsoft utilities are unable to resolve but TRC can successfully recover your database from this problem in the vast majority of cases.
Another common issue relates to either database corruption or problems on the physical medium on which your Exchange data store is located. If you are receiving a message of:
JET_errReadVerifyFailure Read verification error 4294966278
