Hi, today i managed to create a situation for myself, but i am not even sure how. I needed to create another accepted domain within my organization. In addition I decided to create a separate Mailbox DB, which i have put in exactly the same folder as my original one. The Transport Role service which by default uses Network Service account to log on, will not start now. It only works if i change the account to Local System. I have read the various KB articles about permissions for the mailbox DB file folder and they are all set correctly, yet the eventlog is giving me 455,489 and 490 errors, which are all basically access denied messages. The files being denied are in the queue folder and they are trn.log and trn.chk does anybody have an idea on how to fix this? thank you

Please describe the exchange topology Please post the detailed description of the error events About the Transport Role service, you mean the “Microsoft Exchange Transport” service? What the error info/event is after failed to start the service? Can all mailbox databases be mounted successfully? Please run ExBPA against the exchange server for health checkJames Luo TechNet Subscriber Support (http://technet.microsoft.com/en-us/subscriptions/ms788697.aspx) If you have any feedback on our support, please contact tngfb@microsoft.com

Hi,The below post might help.http://social.technet.microsoft.com/Forums/en/exchangesvrtransport/thread/dad1153a-1d27-4aa4-8ffb-c2b81ead2194 Mahendra

single exchange server 2007 sp1. about 115 mailboxes. two databases. both can be mounted and are mounted ran the health check. it appears fine the permissions check appears to be failing but i have a hard time identifying what is causing it to fail. I checked the permissions on the D drive where the DBs are and they seem ok not sure how to ID the permission issue yes I mean the MS Exchange Transport service. sorry about the terminology mixup

it references the permissions but mine seem ok even though the permission check keeps failing and i cant tell why. the report is not quite clear to me

well this is getting even more weird now. running the checks multiple times gives me inconsistent results. now the permissions check comes back overwhelmingly healthy, meaning everything is ok. i checked the permissions manually again and they all seem ok any other ideas? thank you very much

Please verify the status of the mail.que database: 1. Disable the “MsExchange Transport” service on the exchange server 2. Check the status on the queue database using ESEUTIL.EXE /mh 3. If status is “Dirty Shutdown”, please repair the "mail.que" database using ESEUTIL.EXE /p 4. Rename the current "Queue" folder 5. Create new "Queue" folder and Copy the repaired “mail.que” database file back without any log files 6. Start the “MsExchange Transport” service again Notes: we may drop some email as we are replaying from repaired “mail.que” database and without other transaction files.

mail.que was clean. i moved it to a new queue folder anyway and tried what you said, but still no success. the transport service wont start under network service logon

Please increase diagnostic logging level for Transport Service, and reproduce the issue, see if there’s any further related event on the transport server Get-EventLogLevel MSExchangeTransport |set-eventLogLevel -Level High Notes: Please set the level back after the testingJames Luo TechNet Subscriber Support (http://technet.microsoft.com/en-us/subscriptions/ms788697.aspx) If you have any feedback on our support, please contact tngfb@microsoft.com
