Windows Server - Technology : Exchange

Exchange 2007 new recipient / users not appear in GAL

The reason is Offline Address Book not being updated. By default, Exchange generates the Offline Address Book once a day at 5AM.
Besides, an Outlook 2007 client picks up the GAL entries using web distribution from the web based oab virtual directory. The OAB data is delivered to the directory every 8 hours by default.

To change this to 30 minutes, for example, use the following command:
Get-OABVirtualDirectory | Set-OabVirtualDirectory -PollInterval 30

To force a complete OAB update, you can use the following commands:

get-offlineaddressbook | update-offlineaddressbook

update-filedistributionservice %CAS server name%

Run the update-filedistributionservice command for each CAS server.
Of course Outlook 2007 cached-mode users still have to download the OAB again if they want the new information or simply wait 24 hours for it to happen automatically.

In Outlook:

- On the client go to Outlook 2003/2007 | Tools | Send/Receive | Download Address Book….
- Uncheck Download changes since last Send/Receive
- Make sure Download Full Details is checked
- Click OK, wait for the download to complete (depending on your bandwidth and size of OAL, this may be close to instant, or it may take a few minutes)
- Check if the user appears in the GAL

Exchange 2007 server global message size limits in a mix Exchange 2003/2007 environment.

Richard — Sun, 22 Feb 2009 19:03:00 GMT

If you setup your first Exchange 2007 server , global message size limits are configured as follows:

Outgoing message size : 10240 KB

Incoming message size : 10240 KB

Maximum number of recipients : 5000

The settings can be configured with Exchange 2003 Exchange System Manager. However, it cannot be changed by Exchange 2007 Exchange Management Console or the Exchange Management Shell directly.

In order to change these without Exchange 2003 Management Tools, you can use ADSI Edit to change the following values.

delivContLength Valid input for this parameter is 0 to 2097151 KB.

submissionContLength Valid input for this parameter is 0 to 2097151 KB.

msExchRecipLimit Valid input for this parameter is 0 to 2147483647 recipients.

Brief steps in modifying the global message size limits:

1. In Windows 2003 server CD, under the folder “SUPPORT”, “TOOLS”, extract the files “adsiedit.msc” and “adsiedit.dll” from the file “SUPPORT.CAB”.

2. Copy the above the two file to “C:\WINDOWS\System32”.

3. Click “Start”, “Run” and enter “regsvr32 adsiedit.dll”.

4. Double click on “adsiedit.msc”.

5. Expand “CN=Configuration,DC=easypass.com,DC=com”, “CN=Services”, “CN=Microsoft Exchange”, “CN=EP”, “CN=Global Settings”.

6. Right click “CN=Message Delivery” and select “Properties”.

7. Select the desired entry and click “Edit” to change the value.

You may need to wait some time before the configured settings become effective.
