Hi All, I'm have a problem registering mailboxes with Auto Accept Agent in Exchange 2003. i have created the mailboxes and granted the necessary permissions for the mailboxes and when i tried to register the mailboxes i'm getting the below error message... Error 80040154: Class not registered Error: Unable to get event binding path for xxxx@xxxx.com I used this command to register the mail boxes: C:\Program Files\Exchsrvr\Agents\AutoAccept>cscript RegisterMailbox.vbs /m:xxxx@xxxx.com Thanks in advance...

have you logged on to the mailbox yet? try to open the resource mailbox wait a few minutes and then try registering again. this would help http://technet.microsoft.com/en-us/library/aa997282(EXCHG.65).aspx if still there is an issue, try to move the resouce mailbox to a different database and if that helps. Also Note that: RegisterMailbox.vbs must be run on the Exchange server where the resource mailboxes are located. This script cannot be run remotely.

Hi HereToHelp, Thank you for your reply... I'm sorry that i couldn't mention that i logged in those resource email boxes. But when i tried to register those email boxes only I'm getting this error. Regards. KeerthyP.

1. Have you tried everything the follwoing suggests? http://technet.microsoft.com/en-us/library/bb124104(EXCHG.65).aspx 2. are you running the command from the exchange server where the resource mailbox is located?MCSE | MCITP - Server 2008 | MCITP - Exchange 2007 | MCTS - Exchange 2010

ya i checked and i followed the article to install AAA but still I'm unable to register those mailboxes :( I'm running the command from the exchange server where the resource mailbox is located... Regards. KeerthyP.

have you ever been able to register a mailbox before? if not have you installed it correctly?http://technet.microsoft.com/en-us/library/aa996223(EXCHG.65).aspx also note the following: 1. Please Verify that it has been registerd To verify that Auto Accept Agent is registered as a COM+ component Start Component Services. Expand Console Root, Component Services, Computers, My Computer, and then click COM+ Applications. In the details pane, verify that Auto Accept Agent is present. If Auto Accept Agent was installed to run as Local System, it will also appear in the Services snap-in. 2. The MailboxStatus.vbs script uses Web Distributed Authoring and Versioning (WebDAV) to access the Exchange server. For the script to work, WebDAV must be enabled on the Exchange server. 3. If this script is run on the Exchange server, you must add the name of the server to the Internet Explorer trusted list. MCSE | MCITP - Server 2008 | MCITP - Exchange 2007 | MCTS - Exchange 2010

Hi Frank, Thanks for your reply. i found the Event ID 116 on the event log and the SystemMailBox also missing in exchange. this could be the reason for the AAA error. since we have a heavy usage on weekdays we planed to recreate the mailbox storage on this weekend. once it done i will update the status. Thank you very much Frank for spending your valuable time for this... Regards, KeerthyP.
