Add Mailbox Database Copy The wizard could not complete

Asked By 80 points N/A Posted on -

Hi there,

After I have created an active and available group and it was populated and properly configured with Mailbox server members this error appeared. I followed the same steps again and I still have this error. Can anyone tell me please what I did wrong ? Can you help me to make the right configurations ?

Thank you !

Add Mailbox Database Copy The wizard could not complete



This problem is because of an internal error of Exchange Server 2010 SP1 and is a known issue that will occur whenever you add or remove database copies. The command of removing is still successfully followed though the error will appear but adding a database copy to a DAG member isn’t successful.

There’s a registry key in the system that is revoking this issue.

In order to fix that,

1. Start PowerShell.

2. Run the command:
Get-MailboxDatabase "Mailbox Database 02" | fl guid

3. Note the GUID and run the following command in Shell:
Remove-Item HKLM:SoftwareMicrosoftExchangeServerv14ReplayStateccfd3c4a-6187-4253-aa31-99a15c33546cDumpsterInfo

Now, the error is disappeared and your database addition is successful.

For each single database addition, you have to follow the same process.
