Are you unable to write data to Microsoft Exchange Server database? Is your EDB (Exchange Server database file) inaccessible? This behavior may occur due to either low disk space on Exchange Server computer or corrupt EDB file. If the database is corrupt, you need to restore it from the most recent backup to prevent data loss situations. However, in case backup is not valid or updated, you need to opt for Exchange Recovery solutions to retrieve data from the database. In a practical scenario, the Information Store Service of Exchange Server may fail to start and you encounter the below errors in Application Event Log of Exchange Server, while read/writing data from/to EDB file: “Event Type: Error Event Source: ESE Event Category: General Event ID: 482 User: N/A Description: Information Store (4360) First Storage Group: An attempt to write to the file "D:\Program Files\Exchsrvr\mdbdata\res2.log" at offset 4194304 (0x0000000000400000) for 1048576 (0x00100000) bytes failed after 0 seconds with system error 112 (0x00000070): "There is not enough space on the disk.". The write operation will fail with error -1808 (0xfffff8f0). If this error persists then the file may be damaged and may need to be restored from a previous backup.”
