Solve problems Outlook and Exchange Performance

Written by Xaus Xavier Nadal on May 10th, 2012

Good Morning.

For some years that Outlook users with Exchange 2003 are experiencing slow systems, time out, errors, etc .. Each day the amount of mail we receive is higher, the size of e is higher and capabilities of servers they remain the same (subject crisis).

But the mistake that the mail server is responsible, is a wrong way to take on the problem.

Outlook 2003 / 2007 / 2010 like many other mail systems have their limitations and best practices that should follow strictly and only without modifying the Outlook system users and especially without investing in new hardware or even without thinking about upgrading your system mail to a recent version we could achieve very good results in performance mail system is concerned. (The user will thank you.)

One of the major problems and very easy to solve is the number of emails in each folder in Outlook.

This number post should never exceed 3000 post (Sounds like a lot at first, but look at your inbox or sent items folder (How many have ???).

With this simple change we can see a substantial improvement in the performance of our Outlook and therefore in the user feedback regarding the mail system. And if you look also amazing on the Exchange server load.

The contents of each folder is stored in a table in the Information Store Database, as it increases the number of items in each folder mechanism Extensible Storage also called ESE using data structures B + trees to store records also increases and as the number of records increases, the number of I / O disk to store new information also increases and decreases the performance of the entire system.

For those who are using CommVault archiving (Clarification) If you detect that after installing the agent archive, the user reports that when trying to retrieve an archived mail will receive the following error in the Outlook client: Operation could not finish success (If you are unsure about the details please contact your administrator)

Details: Job ID: 1073741846 No detailed information available. Check the CommCell Console QiNetix and log files for details.

Source: Message [mail folder limit exceeded] in folder [Sent Items]

Developing measures to separate the emails into folders that do not exceed the elements 3000 get this error go away and also a substantial improvement in email performance.

Another good practice (this is for system administrators that you have Exchange 2003) is mounting a new mail server Additional 2003 Exchange users there and move up to a limit of 100 database users and 100 GB of space occupied by database (4 storage groups) and balanced database following a scheme similar to the one I designed below:

Storage Group 1

Database 1

Database 5

Database 9

Database 13

Storage Group 2

Database 2

Database 6

Database 10

Database 14

Storage Group 3

Database 3

Database 7

Database 11

Database 15

Storage Group 4

Database 4

Database 8

Database 12

Database 16

With this we obtain that there is an easy way to do load balancing between storage groups in a way as simple as tracking the number of database when the former is full.

For example when 1 has 100 Database users or 100 GB pass to Database 2 already directly in another Storage Group and so on, 3 Database, Database 4, Database 5, ...

I hope you like the article and help you next time.
