A database is approaching its size limit. Exceeding the limit may result in the database becoming unavailable. |
Explanation
This Error event indicates that the Microsoft Exchange Information Store database is approaching the maximum size limit. This error may be logged in either of the following scenarios:
On a computer for which the following is true:
Exchange Standard Edition is installed.
The Information Store database size is approaching the hard-coded limit.
The registry value for the maximum database size was not increased.
On a computer for which the following is true:
Exchange Enterprise Edition is installed.
In the registry, the maximum database size is restricted to the value that is specified in the error.
User Action
To resolve this error, locate the subkey for the Information store in the registry. The subkey should resemble the following:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeIS\<SERVER NAME>\Private-013e2e46-2cd7-4a8e-bfec-0e4652b94b00
Note The GUID in this key (Private-013e2e46-2cd7-4a8e-bfec-0e4652b94b00) is an example only. The actual GUID should match the value of the objectGUID attribute on the Active Directory directory service object of the database.
Caution Incorrectly editing the registry can cause serious problems that may require you to reinstall your operating system. Problems resulting from editing the registry incorrectly may not be able to be resolved. Before editing the registry, back up any valuable data.
If it exists, change the Database Size Limit in GB value to the desired size in gigabytes.
If this value does not exist, add the DWORD value Database Size Limit in GB. Set the value to the desired size in gigabytes.
Note The code for Exchange sets a hard-coded database size limit of 50 gigabytes for Exchange Standard Edition. This value can be changed by using the procedure that is described in this topic. The Information Store database size for both the Standard and the Enterprise Edition is limited only by available disk space.
