The initial error message shown on this thread is as follows:
MailboxStore [RDB01] overwrite property is not checked, please check it and try restoring.
You would need to consider few things:
- Always create, mount and check the "overwrite" options through NMM GUI and not PowerShell.
- Run NMM Config Checkere and ensure you meet all pre-requisites.
- Before starting the restore process ensure all writers (specially Exchange writers) are in status [1]
- Ensure that you start the restore from the node (in DAG) hosting the active DB.
- Ensure that the user starting up the restore process has an active mailbox, and that it is mounted and active.
- Ensure the user has send as-receive as permissions, and storage management permissions as well.
- Ensure the user has Domain admin rights, local admin rights in the exchange nodes and also Exchange Organization rights.
These is basically the first things to check, however, as explained in several times, NMM ConfigChecler is a MUST, and should be always used. This will save yourselves and Support lots of time
that is checked not only one time. If this value isn't set properly you can't start the recovery job. What I have done: 1. Create the RDB 2. Mount the RDB 3. Mark the RDB for override 4. Push the check button -> selected RDB is configured properly for restore 5. Start the restore What can I do more?

Hi,
The RDB is not marked for overwritten. You need to delete the existing RDB using powershell command:
remove-mailboxdatabase RDB_name
The create RDB using NMM GUI as below:
1) Create RDB , Make sure directories are empty before creating RDB.
2) Mount the RDB
3) Mark RDB Overwrite

Hi Mustafa,
that is checked not only one time.
If this value isn't set properly you can't start the recovery job.
What I have done:
1. Create the RDB
2. Mount the RDB
3. Mark the RDB for override
4. Push the check button -> selected RDB is configured properly for restore
5. Start the restore
What can I do more?

Hi Mustafa,
I can check the status of the RDB with the Powershell command "get-MailboxDatabse"
and I got following result:
Name = RestoreDB01
Server = Server-Name
Recovery = True
Replication = None
As you can see above, the override bit is set!
What else can be the problem?
regards

Hi,
What is EX10? Is it a physical node? Or is it a DAG?
1- If EX10 is a DAG then you need to select the DAG client name with FQDN.
2- Verified nslookup and reverse lookup worked for DAG name.
3- Verify that the account has send-as and receive-as permissions.
4- Make the account member of three more Exchange groups:
i) Exchange all hosted Organizations
ii) Exchange servers
iii) Exchange trusted Subsystem, logged off and re-logged on the Exchange.
5- Then open NMM GUI:
a) In the list on the left hand side, select the DAG client with FQDN and click on `Add`
b) Once added, on the top right select the DAG client name with FQDN and try the restore operation again.

Hi Mustafa,
here are my answers:
to 0. It's a physical Node, not a DAG.
to 3. We have verified the access rights for this account.
to 4. We made this account a member of all this groups.
-> same error message after the restore process?!
regards

MailboxStore [RDB01] overwrite property is not checked, please check it and try restoring.
This was the reason, thanks
Made my DB admin to update this setting and it helped - thanks.

Super old thread I know, but do you know if Networker can restore an Exchange DB if the original DB is not on the server anymore? Seems not ...
