After a number of exports or imports, you might need to clean up the failed, completed or other status when running the get-mailboxexportrequest report in PowerShell. To clean these open the Exchange PowerShell and run the below.
Clean Export requests
Get-MailboxExportRequest -Status Completed | Remove-MailboxExportRequest
Get-MailboxExportRequest -Status Failed | Remove-MailboxExportRequest
Clean Import requests
Get-MailboxImportRequest -Status Completed | Remove-MailboxExportRequest
Get-MailboxImportRequest -Status Failed | Remove-MailboxExportRequest
When having especially SBS 2008 with the POP3 Connector to retrieve mail from an outside mailbox to your internal Exchange server, you may encounter the below error in the Event Viewer.
An error occurred while delivering mail to ‘firstname.lastname@example.org’ on the SMTP server ‘localhost’. The error code was 0x800ccc6c. Verify that the mailbox exists and that the Exchange receive connectors are configured properly.
Thou the error message is misleading, this problem can happen if the POP3 Protocol Errors meet the tolerance of the Exchange SMTP Receive connectors. Exchange will close an SMTP connection after a certain number of protocol errors. The default is 5.
To solve the issue, in my case I had to in increase the value of “MaxProtocolErrors” for the Exchange SMTP Receive connectors from Exchange Management Shell by using the below command.
Set-ReceiveConnector -identify “Name of Connector” -MaxProtocolErrors 999
After this, I have restarted the POP3 Connector retrieval of messages and it worked.
When setting up the automatic reply and out of office from your Outlook 2010 having Exchange 2010 you might have the problem with a pop-up saying “Your automatic reply settings cannot be displayed because the server is unavailable”.
I have managed to solve this with a DNS record in your infrastructure. Create the following SRV record to fix the issue.
Port Number: 443
On the client PC run the following to refresh the DNS. Make sure you run the CMD as Administrator
This should fix the problem and the user will be prompted to enter his Out of office settings.
Sometimes you would like to uninstall a mailbox server or un-install a mailbox server but when you make the Get-Mailbox -Arbitration -Database DataBase1 you see some mailboxes there. These are there to prevent you from deleting the mailbox database or server. These are used by the Exchange server. You can either move or delete these mailboxes. If this is not the last mailbox server in your setup I would suggest you move them, otherwise delete them or you will not be able to uninstall the server.
Moving the mailboxes
Get-Mailbox -Arbitration -Database EXCHDB1| New-MoveRequest -TargetDatabase EXCHDB2
Disabling the mailboxes
Get-Mailbox -Arbitration -Database EXCHDB1| Disable-Mailbox -Arbitration
Deleting the mailboxes
Get-Mailbox -Arbitration -Database EXCHDB1| Remove-Mailbox -Arbitration -RemoveLastArbitrationMailboxAllowed
If you would like to re-create them, I would suggest the below
Setup.com /PrepareAD /IAcceptExchangeServerLicenseTerms
.\Setup /PrepareAD /IAcceptExchangeServerLicenseTerms
When importing from PST files exported from an IMAP Server, the messages might not be showing when viewing them in Outlook although they are there. The messages are visible in OWA (Outlook Web Access) and you cannot move emails into the folders when this is done from OWA.
This is because when you import the PST, the messages are imported with the IMAP message format and need to be changed to IPF.NOTE format.
Download the ExFolders from the Microsoft website or from the tools page here.
Extract Exfolders.exe into C:\Program Files\Microsoft\Exchange Server\V14\Bin
Run the Registry file and import it
Make sure you have ‘Manage As’ permissions on the mailboxes you need with the logged in user.
Open ExFolders from the bin folder
Goto Tools and Options
Enable Logging to File
Goto File and select Connect with
Connect by: Database
Select the GC server
Select the Mailbox Database
You should see all the mailboxes listed
Goto Tools and open Custom Bulk Operation
Select Mailboxes as your Base Folder
(&(0x3613001E=IPF.Imap)) in the Overall Filter
Click on the Add button and select Other Folder Properties and click OK
Select Action as Modify
Select PR_CONTAINER_CLASS : 0x3613001E as Property
IPF.Note as Value
Click OK and OK
This should process the folders and emails. From here Exfolders will walk through the mailbox container(s) and change each instance of the PR_CONTAINER_CLASS from IPF.Imap to IPF.note
Though it’s a good security feature to timeout users by default, one can have some issues with people using just OWA to read their mail having to enter the password every 5 minutes. So here’s how to increase the timeout.
By default the Public timeout is 15 minutes where as the Private timeout is of 8 hours.
If you would like to change these simply do the following.
Open registry editor
Create new DWORD named
Create new DWORD named
Now, enter the decimal value in the DWORDs created as required.
Note: The DWORDs entries are in minutes
