Exchange Restrict RAM

Incase u want to limit the size..Follow the steps below

1. Start ADSI Edit.
2. Open the following object:
Configuration/Services/Microsoft Exchange/Your organization/Administrative
Groups/Your administrative group/Servers/Server name/Information Store
3. Right-click Information Store, and then click Properties.
4. Under the list of Attributes, scroll down and select msExchESEParamCacheSizeMax.

5. Click the Edit button, then type the number of 8 kb pages that you
want to set the maximum cache size to.

For example. 1GB cache equates to 1048576 (1024x1024). Divide the cache that you want to set by 8kb to determine the value to enter.


6. Quit ADSI Edit, and then restart the Microsoft Exchange Information Store service

Quorum log too small

The Microsoft® Exchange Server Analyzer Tool reads the following registry entry to determine the size of the quorum log configured for the cluster:

HKEY_LOCAL_MACHINE\Cluster\Quorum\MaxQuorumLogSize

If the Exchange Server Analyzer finds the value for MaxQuorumLogSize less than 4194304 decimal (0x400000 hexadecimal), a warning is displayed.

The MaxQuorumLogSize registry value represents the currently configured value for the Reset quorum log at cluster quorum parameter. This warning is generated if the MaxQuorumLogSize is less than 4096 kilobytes (KB).

The cluster records all changes to the cluster database in the quorum log file. When the quorum log attains the specified size, the cluster saves the database and resets the log file. On Microsoft Windows® 2000 Server-based clusters, the default quorum size limit is 64 KB. On Windows Server™ 2003-based clusters, the default quorum size limit is 4096 KB. For Exchange Server clusters, it is recommended that the Reset quorum log at property be configured to 4096 KB. This ensures that there will be sufficient space to hold the cluster configuration information, such as which servers are part of the cluster, what resources are installed in the cluster, and what state those resources are in (for example, online or offline).
To correct this warning

1. Open Cluster Administrator.
2. In the left pane, right-click the object that represents the cluster, and then click Properties.
3. On the Quorum tab, configure Reset quorum log at with a value of 4096.
4. Click OK to save the changes.

Application log size - CAS Servers

The Microsoft® Exchange Server Analyzer Tool reads the following registry entry to determine the maximum size of the Application log file:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Eventlog\Application\MaxSize

If the Exchange Server Analyzer finds that the value for MaxSize is less than 41,943,040 bytes (40 megabytes ), the Exchange Server Analyzer displays a best practice message.

Setup.com /M:RecoverServer

To recover a server first reset computer in Activity Directory and re-add to domain under same name (Make sure you Reset and not delete)

The run Setup.com /M:RecoverServer on server to recover.

(Hub Transport Server role installed, and this is the only Exchange 2007 Server with this role installed, it's recommended to run Setup.com /M:RecoverServer with the /DoNotStartTransport syntax, as there are a few post-recovery steps that should be completed before this role is made active.)

Errors i received:
- Setup previously failed while performing the action "DisasterRecovery". You can't resume setup my performing the action "Install"
- Setup previously failed while performing the action "Uninstall". You can't resume setup my performing the action "Install"

The problem is that exchange thing he is in a DisasterRecovery, but he isn't ??? To solf this issue:
- Start regedit
- Goto HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\ExchangeServer\v14.0\roleName
Here is the place that exchange says: DisasterRecovery. Just remove the key and try it again.

Error Downloading Exchange Address Book

I seem to be having the same issue i had a few months back where the OAB stops downloading, However if i add the authenticated users to the OAB virtual directory in IIS they can then download the OAB again, however these rights keep on disapearing every week. I raised this on http://social.microsoft.com/Forums/en-US/partnermsgexchange/thread/7c44b1d7-7969-4a76-b0a3-ce1e0bc5894b

So if the offline address book stops downloading to clients please complete the following as a temporary fix:

Go to all 3 of the CAS servers: exchangecas1.domain.com / exchangecas2.domain.com / exchangecas3.domain.com

Goto Internet Information Services (IIS) Manager / expand port.entagroup.com / Sites / Default Web Site /

Right click on OAB and go to Edit Permissions and add authenticated users with Just read right. (you may also need to do this with the actual OAB directory under the OAB directory)

Exchange File Extensions

*.edb - Exchange Database file
E:\database\Accounts\Accounts.edb

*.chk - checkpoint file - keeps track of which transactions have moved from the transaction logs to the database - so in the event of the being an interuption of those transaction logs being moved to the database, if anything happens the checkpoint file can be used to refernece.
E:\log\Accounts\E04.chk

*.log - 2 different types - the current transaction log e.g. E00.log, but once this gets to 1mb it is re-created again and is renamed to e.g. E00000000001.log
E:\log\Accounts

*.jrs - Used if the server gets to the end of its storage space and has no more room to wright any more information into transaction logs (There should be 2 of these logs just for an emergency like that)
E:\log\Accounts\E04res00001.jrs

tmp.edb - Tempory workspace to store data before written to main *.edb database
not present in 2010 - i think its now E:\database\Accounts\Accounts.edb.IRS.RAW

Testing your mail server security

.

Also, check whether your email server divulges your internal users by supporting the EXPN and VRFY commands (for example, VRFY administrator -> admin@example.org):

' telnet 25

help - does it show EXPN / VRFY to be supported?

EXPN administrator

Finally, check if it's possible to send a spoofed email through the email server. For example, SMTP server for domain "example.org" receives an external email from john.smith@example.org. Does your email server drop this email? It should do
