Removing Disconnected Mailboxes in Exchange 2007

Whenever we disable ore remove any mailbox, by default it goes in disconnected state and can be viewed in disconnected mailboxes view in EMC.

For disabling any account you can run following command
Disable-mailbox user@domain.com

You can also remove any account without providing confirm parameter. Confirm parameter will permanently delete the account and this account will not be visible in disconnected mailboxes view
Remove-Mailbox -Database <Database-Name>

If your account is not visible in disconnected mailboxes view you can confirm it by running following command

Clean-mailboxdatabase -identity "<server name>\<storage group name>\<mailbox database name>"

If you want to permanently delete your account then you have to run this command Remove-Mailbox -Database <Database-Name> -StoreMailboxIdentity <MailboxGuid> -confirm:$false

For finding GUID you have to run this command

Get-MailboxStatistics -server <server name> | where-object { $_.DisconnectDate -ne $null } | Select DisplayName,MailboxGuid

You have to copy the GUID and then paste in the above command for permanently deleting any account

If you want to remove all disconnected mailboxes then you have to first run following command

$users = Get-MailboxStatistics | where-object { $_.DisconnectDate -ne $null } | Select DisplayName,MailboxGuid

Now you have all users in Variable users, you can run following command

$users | ForEach { Remove-Mailbox -Database "Mailbox Database" -StoreMailboxIdentity $_.MailboxGuid -confirm:$false }

After this command restart the Certificate service again and the service should run without any issues.

IIS 6.0 thread access Issue

Three weeks earlier i faced an issue in my MOSS environment.I have an enterprise MOSS farm environment consists of 6 Front-end servers and 5 Application servers. During installation of portal AV solution on these servers, i found that IIS on 5 of these servers were not responding. I opened IIS administration console but nothing was showing. I restarted IIS on all servers but no luck, then i did some research on it and found following MS KB on the same issue

"You may be unable to manage IIS 6.0 by using Server Manager if two threads access IIS 6.0 at the same time"


As per this KB this issue is because "two threads access IIS 6.0 at the same time. In this scenario, you may be unable to manage IIS 6.0 by using Server Manager."
Also regarding SharePoint as per this KB "This problem is likely to occur for the SharePoint Timer service (OWSTimer.exe) in Microsoft Office SharePoint Server 2007. When this problem occurs for the SharePoint Timer service, you may experience the following symptoms:
  • In SharePoint Server 2007, tasks that are scheduled do not run.
  • When you try to manage IIS 6.0 by using Server Manager, you receive a blank page, or you receive the following error message: The path specified cannot be used at this time"
There is an hot-fix mentioned in this KB but it is not publicly available, one has to request Microsoft support for acquiring this. I got this hot-fix from my Microsoft account manager within an hour (because of our good relationship with them ;)) and had applied it instantaneously. The issue was fixed after this patch and haven't occurred yet.

I think that this hot-fix will be included in new windows 2003 service pack(SP3) and also might addressed in IIS 6.0 successor i.e IIS 7.0.

Using SharePoint designer 2007 for backup and restore SharePoint 2003 sites

Before release of SharePoint designer, SharePoint sites can be backed-up and restore by using “smigrate” or “stsadm” tool.

Following are the simple steps which can be followed for backing up and restoring any SharePoint site.

LCS 2005 End point Issue

Recently I faced an issue in LCS 2005, the users were reporting that they are unable to login on LCS and getting Server not found issue. Some users were complaining that they are unable to send messages. After viewing events in server I found following error;

Event Type: Error
Event Source: Live Communications User Services
Event Category: (1006)
Event ID: 30903
Date: 3/30/2008
Time: 11:49:08 AM
User: N/A
Computer: XXXXX
The Endpoint expiration stored procedure failed. It will be retried, but if this error continues to occur, the Live Communications Server service will need to be restarted.
Error code: 0x80004005
Cause: Possible issues with backend database.
Ensure the backend is functioning correctly.
For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.

after googling I found 1 KB article on this issue explaining the cause and fix of this issue
As per MS KB "This problem occurs because of a deadlock condition on the back-end Microsoft SQL Server database. When there is a deadlock condition, SQL Server automatically selects one of the set presence calls as the deadlock victim"

I have checked my back-end SQL server and found some process in deadlock state. I have checked with my backup guy and found that there was an unscheduled backup running on LCS database at that time. I requested to stop this backup and tried to restart LCS services but it didn't work. Then I ran following command mentioned in the KB as a workaround of this issue.

OSQL.EXE -S local\&lt;instance name&gt; -d rtc -E -Q "exec sp_MSforeachtable 'dbcc dbreindex(''?'')'"

Apparently this command was succeeded and showing some messages. One of the messages was informing about a deadlock process and a returning transaction. After this I have restarted the LCS service and checked event viewer once again, but the problem remained same. Then I stopped the LCS service and then re-ran the above command which was succeeded without any issue. Then i restarted the LCS service and checked the event viewer and all were normal.

It seemed to have some indexing issues with the LCS database; I will further investigate on it and try to find out the core cause. Meanwhile I have already initiated a request to Microsoft for this hotfix.
