Hi ... Hoping someone can assist me with the following problem. I was told to submit this question to this forum. I have a Windows Server 2008 R2 Domain Controller and Exchange 2007 version 8.03.0192.001. We have approximately 250 users configured with Exchange mailboxes. We have an account named "Account_1" that has "Full Access Permission" to all mailboxes. However this account is unable to access approximately 9 mailboxes. I have tried the following to correct this problem: 1. Delete and re-add "Full Access Permission" within Exchange. 2. Re-boot Exchange. 3. Opened Active Directory, opened the user account, clicked the "Security" tab, clicked "Advanced", un-checked "Include Inheritable Permissions from this object's parent" checkbox, clicked "Add" on the security pop-up window, clicked OK. I then re-checked the checkbox and clicked Ok. Step number 3 temporarily fixed the problem but a few hours later the problem re-appeared. Any suggestions ? JD

I feel Include Inheritable Permissions are getting removed on its own. Can you verify now. is Include Inheritable Permissions Checked ? Go to any one of your DC and run "repadmin /syncall /Aped" You are trying to sync your DC's verify you don't have replication Errors" Regards Satheshwaran Manoharan

Hi Satheshwaran, The "Include Inheritable Permissions" is checked. There do not seem to be any errors with replication. We have two Domain Controllers in our environment. I executed the following two commands on the Primary Domain Controller. Could this be a case of corrupted mailboxes ?: repadmin /replsum * /bysrc /bydest /sort:delta repadmin /replsum * /bysrc /bydest /sort:failures Here are the results: Beginning data collection for replication summary, this may take awhile: ..... Source DSA largest delta fails/total %% error AD2 31m:42s 0 / 5 0 AD1 31m:30s 0 / 5 0 Destination DSA largest delta fails/total %% error AD1 31m:43s 0 / 5 0 AD2 31m:31s 0 / 5 0 JD

I forgot to mention the following Satheshwaran, Exchange 2007 (version 8.03.0192.001) is installed on a Windows 2003 R2 Standard Server 64-Bit with SP2. Our Domain Controllers are Windows Server 2008 R2 Standard 64-Bit. Regards, JD

Hello, Just for a test to grant the Full Access Permission to another user and see if it works properly. Thanks, Simon

Hi Simon, It's the same result with another user. Thanks, JD
