By default the Display Name of Exchange Mailboxes is in the format of “Firstname Lastname”. To change this for an existing mailbox to “Lastname, Firstname”, use the Exchange Management Shell command below.

Get-Mailbox “User Name” | Get-User | ?{ $_.Lastname -ne $null } | %{ $dispName=$_.LastName + “, ” + $_.FirstName ; set-mailbox $_.SamAccountName -Displayname $dispName }

In case you want to revert back to the format “Firstname Lastname”, here’s the command for that.

Get-Mailbox “User Name” | Get-User | ?{ $_.Lastname -ne $null } | %{ $dispName=$_.FirstName + ” ” + $_.LastName ; set-mailbox $_.SamAccountName -Displayname $dispName }

You might have encountered the case where you (or someone else) created a regular mailbox, that should have been a shared mailbox? There is help.

The type of mailbox can easily be changed by using the appropriate Exchange Management Shell command from below.

Regular Mailbox
Set-Mailbox -Identity {Mailbox Name} -Type Regular

Room Mailbox
Set-Mailbox -Identity {Mailbox Name} -Type Room

Equipment Mailbox
Set-Mailbox -Identity {Mailbox Name} -Type Equipment

Shared Mailbox
Set-Mailbox -Identity {Mailbox Name} -Type Shared

Note: There might be further setting changes required in addition to above commands, i.e. for a shared mailbox: granting people access, for room mailboxes: setup of auto-accept features etc.

The members of Distribution Groups can be viewed and modified through the Outlook Address Book. However, Outlook doesn’t offer a way to export a list of all the members.

Administrators can run the following Exchange Management Shell commands to display/export the memberlist, sorted by DisplayName.

Single Distribution Group

• Display Memberlist
  Get-DistributionGroupMember {Name of Group} | Sort -Property DisplayName | Select DisplayName, Alias, Department

• Export Memberlist to TXT file
  Get-DistributionGroupMember {Name of Group} | Sort -Property DisplayName | Select DisplayName, Alias, Department > C:DGmemberlist.txt

• Export Memberlist to CSV file
  Get-DistributionGroupMember {Name of Group} | Sort -Property DisplayName | Select DisplayName, Alias, Department | Export-CSV C:DGmemberlist.csv

All Distribution Groups in the Exchange Organization

• Display Memberlist (create a script file called something like C:scriptsGet-DGmembers.ps1, paste below commands into it, and run the file in the Exchange Management Shell)
  get-distributiongroup | Sort -Property DisplayName | foreach {
  $name = $_.displayname
  $output = ‘Group Name: ‘ + $Name
  write-output $output
  Get-DistributionGroupMember $name | Sort -Property DisplayName | Select DisplayName, Alias, Department
  write-output “” “”
  }

• Export Memberlist to TXT file (create a script file called something like C:scriptsExport-DGmembers.ps1, paste below commands into it, and run the file in the Exchange Management Shell)
  write-output “” > C:outputDGmembers.txt
  get-distributiongroup | Sort -Property DisplayName | foreach {
  $name = $_.displayname
  $output = ‘Group Name: ‘ + $Name
  write-output $output >> C:outputDGmembers.txt
  Get-DistributionGroupMember $name | Sort -Property DisplayName | Select DisplayName, Alias, Department >> C:outputDGmembers.txt
  write-output “” “” >> C:outputDGmembers.txt
  }

Here’s an Exchange Management Shell command that generates a report with mailbox sizes and item counts of all mailboxes within the Exchange Organization, sorted by mailbox size:

Get-MailboxStatistics | Sort -Property TotalItemSize | ft DisplayName, @{expression={$_.totalitemsize.value.ToMB()};label=”Mailbox Size (MB)”}, itemcount

If you require to have this report exported to a text file, the command below will do the trick.

Get-MailboxStatistics | Sort -Property TotalItemSize | ft DisplayName, @{expression={$_.totalitemsize.value.ToMB()};label=”Mailbox Size (MB)”}, itemcount > C:MailboxSizeReport.txt

The 500 – Internal Server Error is displayed when you access Outlook Web Access from https://CASServer/exchange while https://CASServer/owa works fine.

This happens when you have separate Exchange 2007 Mailbox and CAS servers. Ideally the request should be redirected to /owa but you get the 500 – Internal Server Error right after typing in your credentials in the forms login page.

The redirection is not working because ISAPI Extensions are not installed on the Mailbox Server. ISAPI extensions handle specific incoming requests to the IIS server. The extensions are loaded when they are first needed and kept in memory until the host process shuts down.

To fix this issue, install the ISAPI Extensions on the mailbox server. This can be done by using the following command:

ServerManagerCmd -i Web-ISAPI-Ext

When the install is complete, restart IIS.
