Hi All, One of my user is experienceing problem. Every couple of hours outlook 2007 is asking for username and password and the credential window it is showing mailboxserver.domainname.com is asking for username and password. Exchange is running on CCR enviorment. but I am surprised because mailbox server is asking for authentication. If anyone can help.

Hi Does your autodiscover function works properly? Both internal and external? What type of certificate are you using?Jonas Andersson MCTS: Microsoft Exchange Server 2007/2010 | MCITP: EMA 2007/2010 | MCSE/MCSA Blog: http://www.testlabs.se/blog

Have you tried looking at the saved passwords on the PC? Open profiles and then click advanced. Delete the saved passwords and then try again. Good luck.

worst case scenario re-configure the profile. I ran into the same issue couple of times and fixed it doing above or re-configured it.

Hi All, Autodiscover is working properly. I have cross-checked autodiscover url. I have checked the certificates. They are also okay. Certificates contain proper url. I mean webmail.mydomain.com Now the problem is only one user is facing this issue. Test which had been done. 1. Test-outlook configuration. Everything came normal. 2. Recreating the profile. 3. changed authentication method of outlook anywhere. on outlook side. Under exchange proxy settings. 4. Disabled Exchange proxy settings completly from outlook side. Still problem persist. MAIN THING WHICH IS SURPRISING ME IS THAT OUTLOOK IS ASKING FOR USERNAME AND PASSWORD FROM MAILBOXSERVER.MYDOMAIN.COM. tHANKS IN ADVANCE FOR ALL YOUR HELP

you can right click the outlook icon in the task bar and select the Test-Email Autoconfiguration- there tyoe your email and password and thest the configurations in the check box one by one. i presume your outlook is using MAPI.

I have run Test-Email Autoconfiguration. I am running this test while user is connected in Local LaN thourugh outlook. Not quite what you are trying to ask about MAPI. I believe MAPI connectivity means throough outlook Please correct me if I am wrong. Thanks again,

Hi VM, I have run the test. And got the below information. Please let me know if anything is wrong. Display name: test protocol: Exchagne RPC Server: mailboxserver.mydomain.com Login Name: test Availability Service URL: https://webmail.mydomain.com/ews/exchagne.asmx OOF URL: https://webmail.mydomain.com/ews/exchange.asmx OAB URL:https://webmail.mydomain.com/oab/965786b-eae0-402909c87-65436 Unified Message Service URL: https://webmail.mydomin.com/unifiedmessaging/service.asmx Auth Package:Unspecified Protocol: Exchange HTTP Server: webmail.mydomain.com Login Name:test SSL:Yes Mutual Authentication: Yes Availability Service URl: https://webmail.mydomain.com/ews/exchange.asmx OOF URL: https://webmail.mydomain.com/ews/exchange.asmx OAB URL:https://webmail.mydomain.com/oab/965786b-eae0-402909c87-65436 Unified Message Service URL: https://webmail.mydomin.com/unifiedmessaging/service.asmx Auth Package: Basic Certificate Principal name:msstd:webmail.mydomain.com

can you cop the results from Log TAB

I'd also suggest to completely delete the profile and setup a new one.

Hi VM, I have reconfigured the profile some three times.

Hi VM LOG tab results are as below. Attemping URL https://webmail.mydomain.com/autodiscover.xml found through SCp Autodiscover to https://webmail.mydomain.com/autodiscover.xml starting Autodiscover to https://webmail.mydomain.com/autodiscover/autodiscover.xml succeeded (0x00000000)

is it possible for you to configure the same user outlook profile on a different computer?

Hi VM, Actually because of this Same pc had been formatted three times. But as you are telling to ry on different machines. That has not been done.

I wanna keep it KISS (Keep It Simple Stupid) approach :) before i get into more troubleshooting. Simply logong with that user account to another desktop and configure it. You never need to format a PC ffor such issues :)

Let me check on that VM.

Hi, You can press Ctrl+right click Outlook icon in System Tray, select Connection Status, check which type of the connection is connecting not Established, and let me know. Maybe we need to dump the problematic user's attribute and the working user's, then compare them and find the difference. You can also try the simple way to handle this issue: Move the problematic user to another database, and check it. Thanks AllenAllen Song
