Troubleshooting Exchange

We do Exchange discovery look-ups in four ways:

• LDAP
• SCP
• EWS
• autodiscover

Troubleshooting all that can be challenging.

LDAP Browser

http://www.ldapbrowser.com/download.htm

This is just a browser so is safe to use, it can't change anything. The thing is to log in using the credentials you gave Retain, if you can do that it will work for an archive job. But in real life it will be more difficult than that. Log in as the Administrator user to find the actual credentials and path of the ApplicationImpersonation account. Then go back and figure out how to log in to AD with them and see all of the tree. Then make sure Retain is set with those properties and use the EWSEditor Log Viewer Tool to find how it works or fails.

EWSEditor

http://ewseditor.codeplex.com/ A more dangerous tool since it can change entries. Log in as the Impersonation user to the Impersonation Mailbox Use the Autodiscover Viewer Tool to attempt to access other mailboxes on the system and look in the EWSEditor Log tool to see what steps it is going through to reach the user.

MS Remote Connectivity Tester

https://testconnectivity.microsoft.com/ An online tool that can be helpful to narrow down issues.

Exchange Management Shell

In the Exchange Management Shell, not the regular powershell, on the Exchange server run the following command:

Get-WebServicesVirtualDirectory | fl >C:\ews.txt

The results should look something like this:

This is a quick report of the systems settings. The important thing to check is that BasicAuthentication is set to True.

IIS

To restart IIS immediately run PowerShell as Administrator and run the command "ISSRESET" and it will restart IIS immediately.
