Delete emails in multiple mailboxes in Exchange 2010 SP1

Export-Mailbox is no longer supported in Exchange 2010 sp1, in stead there is New-MailboxExportRequest but the problem is that “-DeleteContents” is not supported with mailbox export.

In order to be able to search and delete emails from multiple Exchange 2010 mailboxes one has to have the following roles assigned.

New-ManagementRoleAssignment -Role "Support Diagnostics" –User username

New- ManagementRoleAssignment -Role "Mailbox Import Export" -User username

above will ensure that a user has proper permissions to perform this command.

In order to find and delete a certain email from one mailbox you can perform the following command

Search-Mailbox -Identity username -SearchQuery 'subject:"Email Subject that you want to search for"' –DeleteContent

this can be run for all mailboxes on a server as well

Get-Mailbox –Server “*servername*” –ResultSize unlimited | Search-Mailbox -SearchQuery 'subject:"Email Subject that you want to search for"' –DeleteContent

The system administrator has set policies to prevent this installation

While trying to install an msi following prompt appears

ScreenShot486

and the following event is logged in the event log

Event ID – 7000

c:\downloads\filename.msi is not permitted by software restriction policy. The Windows Installer only allows installation of unrestricted items. The authorization level returned by software restriction policy was 0x0 (status return 0x800b010c).

Resolution

This error means that there a revoked certificate your certificate repository from the maker of the software you are trying to install. Once the revoked certificate is deleted, installation would work fine.

To remove the revoked cert follow the instruction below.

Open Internet Explorer, go to Internet Options –> Contents –> Certificates –> Untrusted Publishers –> Remove the publisherScreenShot487

In my case it was Quest Software

ScreenShot489

Close Internet Explorer and try the installer, it should work fine now.

Couldn't find public folder–When Get-PublicFolderStatistics is run in Exchange 2010 SP1

 

When I tried the following cmdlet in EMS

Get-PublicFolder '\PublicfolderName' -Recurse | Get-PublicFolderStatistics

I got the following error

Couldn't find public folder "\PublicfolderName" on server "server.domain.org".
    + CategoryInfo          : InvalidData: (\PublicfolderName:PublicFolderIdParameter) [Get-PublicFolderStatistics], InvalidOperationException
    + FullyQualifiedErrorId : 773CD1AB,Microsoft.Exchange.Management.MapiTasks.GetPublicFolderStatistics

Couldn't find public folder "\PublicFolderName\subfolder" on server "server.domain.org".
    + CategoryInfo          : InvalidData: (\PublicFolderName\subfolder:PublicFolderIdParameter) [Get-PublicFolderStatistics], InvalidOperationException
    + FullyQualifiedErrorId : 773CD1AB,Microsoft.Exchange.Management.MapiTasks.GetPublicFolderStatistics

Solution

This seems to be bug (may be a feature :)

If you add the resultsize parameter to the cmdlet it works fine

Get-PublicFolder '\PublicfolderName' -Recurse | Get-PublicFolderStatistics –ResultSize unlimited

Windows 7 + RemProf = Windows XP + Delprof

It has been a while since I have been looking for a remote profile deletion utility for Windows 7. Microsoft provided Delprof for Windows 2000, XP and Server 2003 but it doesn’t work on any OS beginning with Vista. We are in the process of transitioning to Windows 7, out user support guys make heavy use of Delprof as we use Roaming Profiles which get corrupted or have other issues at time or we simply need to clean a workstation. So in the absence of Delprof our user support needs to login to the workstation to clear profiles on a workstation or login to a XP virtual machine and use the command prompt for remote profile deletion.

While  looking for a solution I found the following freeware utility

RemProf download and look at the help file for more info.

Using it with PsExec one can achieve what Delprof does and more. It makes a better Delprof alternative.

for example if you need to delete only one users profile from a workstation, you can user the following command

psexec \\computername \\uncpath\remprof /L username

there are many more options, following is from the help file that comes with it.

Usage:
REMPROF [/LIST|username|/A|/D:days|/AD:days] [/EXCLUDE:usernames] [/?]

/LIST - List all user profiles currently not in use (Default).
username - Delete user profile based on username.
/A - Delete all user profiles that have no username association
including abandoned profile folders.
i.e. The username has been deleted in Active Directory but
a profile still exists in form of a SID or the profile did
not unload correctly and a residue profile folder exists.
/D:days - Delete all user profiles equal to or older than the number of
days specified. NB: /D: without a number is equal to /D:0.
/D:0 will remove CURRENT user profiles not in use.
/AD:days - Delete all user profiles that have no username association
and are equal to or older than the number of days specified.
NB: /AD: without a number is equal to /AD:0.
/EXCLUDE:username/s - Exclude particular users from being deleted.
Can accept multiple entries, seperated by comma.
Must be last command line argument.
Unassociated profiles cannot be excluded.
Do not include the Domain Name.
/? - show this help file

REMPROF without parameters will execute the /LIST switch by default.

I find it a very useful tool, hope it helps you too.

Installing Exchange 2007 SP2 Management Tools on Windows 7 SP1

We recently deployed Windows 7 SP1 64bit to all the IT staff and the user support team required Exchange Management Tools installed on their workstations.  I just asked them to go ahead and copy the installer on the local disk and fire up the installation as administrator and choose management tools in a custom installation. I was told that there was a compatibility  issue error while doing the installation.

Resolution

I installed the following features just to make sure that the perquisites are met.

  • IIS 6 Management Console
  • IIS 6 WMI Compatibility
  • IIS Metabase and IIS 6 configuration Compatibility
  • IIS Management Console

ScreenShot411

I tried the installation again as administrator and checked the compatibility mode to Vista SP2, got the following error.

ScreenShot412

So trusting in the good old restart trick Smile I restarted and ran the same setup as administrator and compatibility mode (right click > Properties > Compatibility) Vista SP2. It worked like a charm!

ScanMail for Microsoft Exchange – Java virtual machine is not installed

After a successful installation of ScanMail on our Exchange 2010 sp1 servers, when I tried to login to the Management site, I received the following error

image

Server had Internet Explorer 8 installed, I though I should try it from my Windows 7 64bit machine just to make sure that its not just the server. I received the same error on my workstation as well.

I am sure Java was installed correctly and was enabled for IE and Firefox, I tried opening the site in Firefox and got same error on all 64bit machines.

Resolution

Fix was simple

I had to install 32bit version of JRE on all 64bit machines. That solved the issue for all browsers.

thought this might be helpful for some out there.
