Hi Mike, Which version for your exchange 2003 server, Microsoft Exchange Server 2003 Service Pack 2 (SP2) must be installed before you apply this hotfix. You could refer to below for the latest service pack: http://support.microsoft.com/kb/836993/ If there still has some issue, please tell us. Regards!

Hi, Yes, sorry I didn’t' get back. Interesting. I attempted to install the Hotfix [http://support.microsoft.com/kb/836993/ ] that was for Exh2003, but it errored out saying it wasn't for the version installed. After that I haven’t had another problem reported with calendar updates. I am sure I didn't fix anything, but it seems to be working now. Makes me wonder though. Mike

Hi, I have environment Exchange 2003 and SP2 installed, since 1 month we also facing similar problem. Few of the calendars sent to external email ID’s remains in mail queue, first we will get delayed notification and then NDR. Please help me in fixing this problem. Thanks & Best regards Raj
