The source or destination. Mailbox imports and exports are available only in the Mailbox Import Export role, and by default, that role isn't assigned to a role group.
To use these features, you need to add the Mailbox Import Export role to a role group that you belong to for example, the Organization Management role group. For more information, see Add a role to a role group. As an administrator, you might need to import. For example:. Compliance requirements : You can export a mailbox to a. After the export is complete, you can import the. Create a point-in-time snapshot of a mailbox : Suppose you're keeping a backup of an entire mailbox database for just a few mailboxes.
I still think the replication service is the issue, which also makes me think it's network related because the same issue is present when using iSCSI on a private network. Besides, I suggest you use server health and performance to check if there is any error related to the replication service.
Thank you for your feedback. ESEUTIL is a low level database repair tool, while isinteg is high level and can perform operations on individual mailboxes. Operations performed using isinteg can delete or remove corrupted mailboxes, whereas ESEUTIL can delete certain sections of the database to repair it and it can include a significant portion of mailboxes.
I would like to restore the database from a previous windows backup, but I am unsure if this will modify any exchange settings, if I am to restore it to a different location. I would like to use the restored database as the target database for those two utilities. On another note, I have successfully exported a mailbox when it was the only mailbox being exported.
I see no errors in the logs, everything is running great. I ran a server health performance tool and all is well. Exporting that mailbox took 4 hours to complete. When I was moving mailboxes from an old exchange server to the new one I had modified the replication service config file so I could move more mailboxes at a time.
I am unsure if that has a role in the service failing after running for so long. Here is the output of that file. Output is below:. If you do full backup for your database, you can restore the database from a previous windows backup, and this will not modify any exchange settings.
I started a restore using the file and folder option. I selected the database file to be restored to the desktop. The process was running great until the system was so bogged down it caused exchange to slow down. I have the backup volume in a RAID 0 with two drives. I know the risks and implications of running the backup volume in a RAID 0, I was only working with what I had available for drives and that met the space requirements we required without incurring a cost and while we were preparing an actual back up solution.
As you can imagine, I have the OS volume utilizing the read and write speed of one HD while the backup volume can read and write at the speeds of two drives. I can only think that the restore was reading from the backup volume faster than it could write to the OS volume. As a result the operation had appeared to then use the system memory to cache the data, while doing this the store. I just figured this is why the system had slowed down to the point of causing exchange to freeze any incoming connections.
Office Office Exchange Server. Not an IT pro? During the Modern hybrid configuration, you will be asked to input the credentials for the on-premises migration admin — these can be the same credentials inserted in the beginning of HCW or new ones. The on-premises Migration admin credentials are needed by HCW in order to run the Test-MigrationServerAvailability cmdlet and this account can have lesser privileges than the admin account running HCW which is Organization Management role.
Supposing that you get a timeout error in HCW when testing migration server availability, you would first search in the HCW log for the Test-MigrationServerAvailability cmdlet executed by HCW, copy-paste the exact command to a Notepad file or at least make a note of the RemoteServer value and then connect to Exchange Online PowerShell and run the same command to confirm the error message thrown by HCW.
Once you are successfully connected to EXO PS, run the same command that HCW ran in the log file to see if you get same error or different one, providing the credentials for the on-premises migration admin and your RemoteServer value:. Once you confirm that you still get the error that HCW was complaining about and you are running Modern Hybrid Mode, you would need to investigate it.
There are two ways to do this:. If the request counters for of requests go up on the Agent machine when you do Test-MigrationServerAvailability to the Hybrid Agent, the problem is likely on the on-premises server; if they don't, the problem is probably with either the connector or the cloud configuration. If we suspect on-premises most likely the case , you need to check again the on-premises infrastructure, especially proxy and firewall settings.
Several things that might be helpful: install requirements , system requirements , port and protocol requirements. This is an extract from HTTP proxy logs with a error code and a timeout when proxying to another Exchange server:.
Follow this article , as it is applicable for both Modern and Classic hybrid topologies. Check this support article. Make sure on-premises migration Admin has at least Exchange Recipient Admin permissions or Recipient Management, depending on the Exchange version. If you are running Modern HCW, usually this is the same on-premises account that has Organization Management rights, but if you change the account, you would see here if the permissions are right or the credentials are correct when we would input account credentials.
We recommend that you create do not copy account another on-premises account that purely has Exchange Recipient Admin permissions, then test with that account Test-MigrationServerAvailability :. Do you have devices that pre-authenticate the requests coming from Exchange Online to Exchange on-premises servers EWS and Autodiscover paths?
If yes, this is not supported. If you are not sure of it, we recommend you temporarily bypass network devices in front of Exchange Servers, allow direct access to Exchange Servers and see if same error when doing Test-MigrationServerAvailability. Negotiate provider is falling back to NTLM if Kerberos is not possible and with external clients that is always the case.
It is also a good practice to check the WWW-Authenticate headers both from external and internal PC and notice if there are differences in the output for example you see Basic, Negotiate, NTLM from internal — all ok but you see only Basic from external — not ok.
See Verifying Connectivity section from here. For Classic hybrid, a valid 3 rd party valid certificate is required for EWS. See this and this. You can use the following command in Exchange Management Shell to quickly check the Exchange certificates and some properties on them from all your Exchange servers in the organization:.
This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details. See here how to enable the former ones. You can narrow down the statuses between as an example for this situation. You would check the network devices that are in front of the Exchange Servers firewall, reverse proxy, load balancer. If the Hybrid Agent is inactive, then check if the Hybrid Service is installed and running, reference here.

The Mailbox Replication Service MRS has a proxy endpoint that's required for cross-forest mailbox moves and remote move migrations between your on-premises Exchange organization and Microsoft or Office Cross-forest enterprise moves : For cross-forest moves that are initiated from the target forest known as a pull move type , you need to enable the MRS Proxy endpoint on Mailbox servers in the source forest.
For cross-forest moves that are initiated from the source forest known as a push move type , you need to enable the MRS Proxy endpoint on Mailbox servers in the target forest. Remote move migrations between an on-premises Exchange organization and Microsoft or Office For both onboarding and offboarding remote move migrations, you need to enable the MRS Proxy endpoint on Mailbox servers in your on-premises Exchange organization.
