How To Create Shared Mailbox In Exchange 2010

Open the Exchange Shell and type the following command:
New-Mailbox shared –shared –userprincipalname shared@jermsmit.com

If the mailbox was already a user mailbox and you are converting to shared type the following command:
Set-Mailbox -Identity shared@jermsmit.com -Type Shared

You can now verify that the box is indeed a shared mailbox by typing the following command:
Get-Mailbox -Identity shared@jermsmit.com | Format-List RecipientTypeDetails

Removing an auto-mapped mailbox

In Exchange Server 2010 SP1, shared mailbox with full access rights will be auto mapped to the users given such rights. This is fine for that user who doesn’t seem to know how to add an additional mailbox to their Outlook 2007, 2010, 2013 client. But what about those support and systems admins who grant themselves access for troubleshooting and find out later they are stuck with this new folder under their Outlook folder that can’t be removed.

Well we never say “can’t”. So what you need to do to remote the auto-mapping attribute is to reach out to the administrator if you are not one or if you are just find your way to the Exchange Management Power Shell and issue the following command:

Add-MailboxPermission -Identity <shared mailbox alias> -User <your mailbox alias> -AccessRights FullAccess -InheritanceType All -Automapping $false

Once this command is run the additional mailbox will automatically be removed.

Reference: Disable Outlook Auto-Mapping with Full Access

Issue: Outlook Address Book Not Updating

Symptoms:

New users added to Exchange 2010 do not show up in global address book

Tests Performed:

1. Searched for new users from Outlook – This failed
2. Searched for new users from OWA – This works
3. Put Outlook in non-cached mode and searched – this worked

Suspected Problem:

Offline Address Book Generation is not happening – Possible cause, resources (memory) on host server, service failure.

Steps Taken: *note* I have seen this before so I know where I am looking first

1. Stop the Microsoft Exchange File Distribution Service

2. Stop the Microsoft Exchange Address Book

3. Clear the files from ‘C:Program FilesMicrosoftExchange ServerV14ExchangeOAB’ putting them into a backup folder of some sort.

4. Restart the services above.

5. To get the OAM to immediately generate run the following command: Update-OfflineAddressbook “name of offline address book”. You may encounter an issue stating that the System Attendant Service is not running or you do not have permission. 1. Make sure you are running the Exchange Management Shell as Administrator and 2. The System Attendant Service is running. *note* The Service is named “Microsoft Exchange System Attendant”.

6. You will now notice that the GUIDS and files have started to populate under ExchangeOAB folder

Follow-up Testing that things now work:

1. Exit Outlook and delete the Offline Address Book cache from ‘C:Users%user profile%AppDataLocalMicrosoftOutlookOffline Address Books’

2. Open outlook again cache should repopulate at this point.

3. Open a new email message or click the Address Book and search for the person(s) who were not showing previously.

Conclusion:

The Outlook Client failed to download an updated copy of the Offline Address Book because the services have stopped functioning. I was unable to obtain errors in the event logs regarding this, however having experienced this in the past it has become suspect

Simple Exchange 2010 Database White Space Report

I was looking at some of my database on Exchange that seemed to be very large in size so first thought was that an offline defrag may be needed, but before I reach that point I wanted to know how much ‘slack’ or white space existed in each of my Exchange databases.

This was done by using the following command syntax in the Exchange Management Shell:

To export this into a CSV format the following can also be done, so that you can give to any management members for review of your findings:

Next, I may find a way to setup this to email a weekly report…

Exchange 2010 SP2 | Mailbox Export Request


Exchange 2010 has many improvements.  As we know when things change they do not often stay the same. In this case the method used to export exchange email boxes to PST files. Back in a previous post I went over the steps of exporting a mailbox to PST. To do this all you needed was a system with the Exchange 2007 tools installed and office.  This has changed in Exchange 2010 SP2. I note the SP2 because this is what I am using and the methods have changed from the initial release.

In Exchange 2010, you first need to be assigned the “Mailbox Import Export” role to import or export email boxes.  To assign the “Mailbox Import Export” role to an individual user, use the following syntax:

To assign the “Mailbox Import Export”role to a Windows security group, use the following syntax

In addition to the “Mailbox Import Export” role, the user which will actually perform export / import must also be member of the local Administrators group on the Exchange server on which the export operation is taking place.

To run the command to export the mailbox we need to open the EMC and run the following command:

You need to grant read/write (full) permission to the group Exchange Trusted Subsystem to the network share where you’ll export or import mailboxes. If you don’t grant this permission, you’ll receive an error message stating that Exchange is unable to establish a connection to the target mailbox.

With this new method, the requirement for Office to be installed no longer exists and Exchange 2010 queues up the backup to the UNC folder path specified.
