Outlook always asks for username and password information

TipsMake.com - Currently, there are many users who frequently encounter problems with the Outlook application constantly asking for username and password information while using Exchange 2007. In the following article, we will guide you. Some ways to fix this problem.

Exchange 2007 Service Pack:

In fact, there is a problem with bulletin boards that require continuous password entry, and can be resolved by installing Rollup 9 for Exchange 2007 SP1, but experts have advised everyone. should be replaced with Exchange 2007 SP2 - available from around August 2009, or the Exchange 2007 Service pack 3.

In case you use Small Business Server 2008 and haven't used Exchange 2007 Rollup 9, you can install SP2 for Exchange 2007 with the Installation Tool.

Autodiscover:

In case the above method does not help you solve the problem while using Outlook 2007, please reconfigure autodiscover so that it is correct. You can refer to this article.

However, the most frequently forgotten component is the autodiscover.domainname.com - the string of characters behind @ in the email address. Newer versions of Outlook will automatically search for OAB to download and some other relevant information . If the result is not returned, then Outlook will continue to issue optional notifications for people. use. To fix this, we must have the SSL Certificate which contains the autodiscover.domainname.com path. You can proceed to purchase the Certificate SAN / UCC here for Exchange 2007 and Exchange 2010:

- autodiscover.domainname.com

- owa.domainname.com (URL used for Outlook Web Access)

- remote.domainname.com (used in SBS 2008)

- servername.domainname.local (Internal FQDN parameter of Exchange Server)

- SERVERNAME (name of NETBIOS server)

Kernel authentication mode:

In the Internet Information Services (IIS) Manager section with the Exchange virtual directory defined, if you are using Small Business Server 2008 , you will see this section under the SBS Web Applications website, and if not using SBS, it will be under the Default section. Website

The virtual directories we are looking for at this step are:

- Autodiscover

- EWS

- RPC

- OAB

Check the folders one by one and double-click the Authentication icon in the window on the right. Then, right-click Windows Authentication and select Advanced Settings , check Enable kernel-mode authentication , and perform this step with all virtual directories above.

Internet Explorer Proxy:

This may also be the reason many people encounter it when you use a proxy server, so make sure the exchange server has removed the domain from the list. Or do it manually, open Internet Explorer> Tools> Internet Options> Connections or use Group Policy if you want to apply in a large-scale environment.

Good luck!
