Exchange server database corruption

Hello,

Our exchange server got the following application event log:

Source: ESE
Category: Database Corruption
Type: Error
EventID: 447
User: N/A
Computer: VOYAGER

Description:
Information Store (2624) A bad page link (error -338) has been detected in a B-Tree (ObjectId: 2283, PgnoRoot: 213598) of database E:\Exchsrvr\MDBDATA\priv1.edb (3253654 => 3304833, 3253654).

Right we can still send plain text email using OUTLOOK, but attachments can’t be sent, OUTLOOK will say “The operation failed”.

The interesting thing is, attachments can be sent and received without problems if using web access: http://ip/exchange, instead of OUTLOOK.

Any input would be appreciated. Already stuck here for 4 days. Reboot didn’t solve the problem, by the way.

Thanks!
max
