Problems move a account from exchange 2003 to exchange 2007

I was upgrading a Exchange 2003 to a Exchange 2007, but have some troubles move some accounts to my Exchange 2007 server, it fault whitch this error:
Summary: 1 item(s). 0 succeeded, 1 failed.
Elapsed time: 00:00:10

Failed

Error:
Error was found for XX because: Error occurred in the step: Preparing mailbox to be moved. Failed to copy basic mailbox information with error: The Microsoft Exchange Information Store service could not find the specified object., error code: -1056749241

Exchange Management Shell command attempted:
‘141fc3d8-c100-46e6-b402-fc653b26afe4’ | move-mailbox -TargetDatabase ‘CN=Mailbox Database,CN=First Storage Group,CN=InformationStore,CN=XXXX,CN=Servers,CN=Exchange Administrative Group (XXXXX),CN=Administrative Groups,CN=First Organization,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=XXXX,DC=net’

Some search on the internet and I found out that is using the address list to move a account. And that this users has been set to be hide from Exchange Address list, so removing this checkmark and now the user can be moved.

How to enable out-of-office reply messages to the Internet

By default in Microsoft Exchange Server 2003, the sending of out-of-office reply messages to the Internet is disabled. Many administrators do not allow out-of-office reply messages to be sent outside the Exchange organization to prevent unauthorized people from learning when users are out of the office.

To enable out-of-office reply messages to the Internet, follow these steps:
1. Start Exchange System Manager.
2. Double-click Global Settings, and then click Internet Message Formats.
3. In the details pane, right-click a domain name, and then click Properties. (Note By default, “*” is the SMTP domain.)
4. In the Default Properties dialog box, click Advanced, and then click to select the Allow out of office responses check box.
This allows out-of-office reply messages to be sent under this SMTP policy.

Tweaking mySQL in Debian

This guide is not complete to tweak you mySQL on Debian systems, because a good tweak is depending on what you want to use mySQL to.

Key Buffer:
The key buffer holds the indexes of tables in memory, and of cause a bigger key buffer result in faster row lookups. The bigger this value is the better is it, but preventing swaping. good rule of thumb seems to be to use 1/4 of system memory. key_buffer = 256M

Query Cache:
query_cache_size, as the name say it is the total memory available to query caching. query_cache_limit is the maximum number of kilobytes one query may be in order to be cached. If you set this value to high it will prevent a lot of small query to be cached. Setting it to low will prevent bigger query to be cached.
query_cache_size = 128MB
query_cache_limit = 4MB

Table Cache:
If you application need to open a lot of tables, a important variable is table_cache, it is the number of tables a thread can keep open at the same time.
table_cache = 512

The InnoDB Engine:
Allmost everybody do not use InnoDB engine I mySQL, there are using MyISAM istead. Mysql reserved memory for InnoDB, so you could easy skip this Add skip-innodb to you my.cnf file.

Binary Logging:
If you don’t want to replicate data changes to a second server, and don’t use the binary logging as incredimental backup, you can disable this feature.
Comment out this line:
log_bin = /var/log/mysql/mysql-bin.log
