Thanks for the info. I do indeed get numerical code 5.4.6, but I checked and both the sending (myself) and the receiving mailboxes do not have any alternate recipients set. -----Original Message----- From: Shevill, Mark M SITI-ITDSEC4 [mailto:Mark.Shevill@xxxxxxxxx] Sent: 30 August 2002 12:10 PM To: [ExchangeList] Subject: [exchangelist] RE: Bouncing back and forth.... http://www.MSExchange.org/ Or try this Numerical Code: 5.4.6 Possible Cause: Categorizer forward loop detected. targetAddress attribute is set on a mailbox-enabled user. Hosting Pack: This is a common hosting configuration problem when someone creates a contact in OU1 and creates a user in OU2 with the same e-mail address via user provisioning tool. Troubleshooting: This happens when contactA has an alternate recipient that points to contactB which then has an alternate recipient that points back to contactA. Check the contact's alternate recipient. Check and remove targetAddress attribute from mailbox-enabled users. For hosting where you want to send mail from one user in one company (OU) to another company (OU), you should configure the following two related objects: User: SMTP proxy: user@xxxxxxxxxxx Contact: targetAddress: user@xxxxxxxxxxx; SMTP proxy: contact@xxxxxxxxxxxx Mark Shevill IMG Messaging Deputy Team Leader Shell Information Technology International Limited Rowlandsway, Wythenshawe, Manchester M22 5SB, United Kingdom Tel: +44 161 935 7152 Email: Mark.M.Shevill@xxxxxxxxxxxx Internet: http://www.shell.com -----Original Message----- From: Shevill, Mark M SITI-ITDSEC4 Sent: 30 August 2002 10:59 To: [ExchangeList] Subject: [exchangelist] RE: Bouncing back and forth.... http://www.MSExchange.org/ You have duplicate SMTP addresses.
