I'm working with outlook 2007 and have an exchange server at the back. Upon sending an email to one of my associate, I always prompted with this notification... <!-- /* Font Definitions */ @font-face {font-family:"Cambria Math"; panose-1:2 4 5 3 5 4 6 3 2 4; mso-font-charset:0; mso-generic-font-family:roman; mso-font-pitch:variable; mso-font-signature:-1610611985 1107304683 0 0 159 0;} @font-face {font-family:Calibri; panose-1:2 15 5 2 2 2 4 3 2 4; mso-font-charset:0; mso-generic-font-family:swiss; mso-font-pitch:variable; mso-font-signature:-1610611985 1073750139 0 0 159 0;} @font-face {font-family:Consolas; panose-1:2 11 6 9 2 2 4 3 2 4; mso-font-charset:0; mso-generic-font-family:modern; mso-font-pitch:fixed; mso-font-signature:-1610611985 1073750091 0 0 159 0;} /* Style Definitions */ p.MsoNormal, li.MsoNormal, div.MsoNormal {mso-style-unhide:no; mso-style-qformat:yes; mso-style-parent:""; margin:0in; margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:Calibri; mso-fareast-theme-font:minor-latin; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;} a:link, span.MsoHyperlink {mso-style-priority:99; color:blue; mso-themecolor:hyperlink; text-decoration:underline; text-underline:single;} a:visited, span.MsoHyperlinkFollowed {mso-style-noshow:yes; mso-style-priority:99; color:purple; mso-themecolor:followedhyperlink; text-decoration:underline; text-underline:single;} p.MsoPlainText, li.MsoPlainText, div.MsoPlainText {mso-style-noshow:yes; mso-style-priority:99; mso-style-link:"Plain Text Char"; margin:0in; margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.5pt; font-family:Consolas; mso-fareast-font-family:Calibri; mso-fareast-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;} span.PlainTextChar {mso-style-name:"Plain Text Char"; mso-style-noshow:yes; mso-style-priority:99; mso-style-unhide:no; mso-style-locked:yes; mso-style-link:"Plain Text"; mso-ansi-font-size:10.5pt; mso-bidi-font-size:10.5pt; font-family:Consolas; mso-ascii-font-family:Consolas; mso-hansi-font-family:Consolas;} .MsoChpDefault {mso-style-type:export-only; mso-default-props:yes; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:Calibri; mso-fareast-theme-font:minor-latin; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;} @page Section1 {size:8.5in 11.0in; margin:1.0in 1.0in 1.0in 1.0in; mso-header-margin:.5in; mso-footer-margin:.5in; mso-paper-source:0;} div.Section1 {page:Section1;} --> "Your email to (email address in the distribution list) was not delivered". I have checked the rules & alerts setting on the recipient's terminal and found nothing should prevent her from receiving my email. We think it could due to some setting error on the server, unfortunately the staff who used to manage the server just left the company. Would appreciate any assistance on how we can sort out this issue. Thanks & regards Han

Can others send emails to him? Check the SMTP address of the person.also see if that person can send emails to outside domain and internal users. Raj

Rajnish, Thanks for your response. Yes,....I have checked that others can still reach him and he can also send email to outside. Seems to me that my account being blocked to reach him. Despite rules setting on the client terminal (which will take effect upon arriving of the email on that terminal), is there any server-based rules set on the exchange server that preventing the message being sent to the intended addressee? appreciate your advices Regards Han

No. There is no such rule. Can you reconfigure his and yours outlook profile. Also try to download OAB from your outlook.Raj

what is the behaviour in Outlook Web Access??

Raj, Exchange12, thanks for the advice. Will check further on Monday. Have a great weekend to you all Han

Hi Han, Any update on this issue? If you send mail to him/her via OWA, do it work? Meanwhile, please paste the complete NDR(non-deliver report) here for our further discussion. Please also contact your mail admin for suggestions. Thanks, Elvis

Hi everyone, I got my HQ administrator trying hard to fix this problem. Hopefully you could find the answer. Meantime I do appreciate your help and attention to this issue Thanks Han
