Exchange 2010 quota warning messages issue

  By Remigiusz Szatkowski | 01/10/2012 - 06:06 | , ,

In Microsoft Exchange 2010 environments, Exchange sends a quota message to mailbox owners when mailbox size exceeds:

  • IssueWarningQuota – the lowest storage quota
  • ProhibitSendQuota – the middle storage quota
  • ProhibitSendReceiveQuota – the highest storage quota

 

All Quotas limits can be configured at mailbox or database level.

We can define time when messages are sent by specifying QuotaNotificationSchedule for Mailbox Database.

 

If we want to check QuotaNotificationSchedule use:

Get-MailboxDatabase | select name, QuotaNotificationSchedule

Sometimes in your Microsoft Exchange environment you can experience a problem with HUB or Edge Transport servers, when often messages stuck in Queues.

When you resolve problem with any Exchange server, sometimes it takes few minutes for Exchange to resubmit all emails, time depends on how many messages are in queues.

Until messages have one of the below status, we can manually resubmit them to the Exchange Submission Queue if queue hasn’t Suspended state:

  • mailbox Delivery queues or Remote delivery queues with status Retry
  • emails in Unreachable queue
  • emails in Poison queue

 

To manually resubmit messages in queues, you can use the following methods:

  • use the Retry-Queue cmdlet with parameter -Resubmit
  • export messages from queue to .eml message files and resubmit them by placing in the Replay directory. For Exchange 2010 default location:
    C:\Program Files\Microsoft\Exchange Server\V14\TransportRoles\Replay
  • open Queue Viewer or Resume-Message cmdlet to resubmit messages in poison message queue.

Shared Mailbox deleted and sent items separation

  By Remigiusz Szatkowski | 25/09/2012 - 06:07 | , , ,

Most of us who has used Shared Mailbox in Microsoft Exchange environment, met with users complaints that emails which they sent a message using the shared mailbox account goes to Sent Items personal mailbox.

This behavior is normall for scenario when we use Microsoft Outlook with personal mailbox and automapped shared mailbox. Then when we delete or send message from shared mailbox account, the message goes to personal recycle bin or sent items.

 

How can we separate Shared Mailbox deleted and sent items ?

We have two solutions to separate sent and deleted items:

  1. Use Microsoft Outlook 2010 and add shared mailbox as normal mailbox account
  2. Change windows registry on client computer with different Outlook versions


 

1. Use Microsoft Outlook 2010 for Shared Mailbox to separate sent and deleted items

When you use Microsoft Outlook and you get permissions to shared mailbox, this mailbox will be automapped in Outlook.

After automapping when you send a message from shared mailbox this message will be saved in sent items of your personal mailbox. This behavior often is unwanted.

To make Outlook 2010 to save all sent items or deleted items from shared mailbox to sent items folder or deleted items folder in shared mailbox you have to add shared mailbox as equivalent mailbox in Outlook.

Close Microsoft Outlook 2010 with your personal mailbox, and go to Control Panel, Mail  next in Mail Setup – Outlook window choose:
E-mail Accounts…

Next in Account Settings window choose New…, and select

Manually configure server settings or additional server types

Disable Outlook Mailbox Auto-Mapping

  By Remigiusz Szatkowski | 24/09/2012 - 06:06 | , ,

When Microsoft released Microsoft Exchange 2010 SP1 we’ve discovered new feature that allows Microsoft Outlook 2010 and 2007 clients to automatically map mailbox to which a user has Full Access permission.

So if we add user Full Access permission to 10 mailboxes, he will all 10 mailboxes in his Outlook because these mailboxes will be automatically mapped in Outlook.

In Microsoft Exchange 2010 SP1 there was no option to turn this “great” feature off.

But when we get Microsoft Exchange 2010 SP2 we can use Exchange Management Shell (Exchange Powershell) to disable this feature.

When we use Exchange Management Console to add user Full Mailbox Permission to other mailbox, this mailbox will be loaded to user Outlook.

 

If we want to add user Full Mailbox Permission but we don’t want automap this mailbox to Microsoft Outlook we have to use powershell:

Exchange 2010 and Exchange 2007  recipients limit

There is an important change compared to Exchange 2003 – Distribution group are treated as one recipient.

Unfortunately, if we want to get more information about the mailboxes, or mailboxes that meet that special condition, the realization of such a task in the EMC will be very time consuming.

Sometimes (for example, after a small disk array failure ;)) you need to resume failed and suspended database copy. We can do that with this  command: resume-mailboxdatabasecopy .

But what if there is a lot of databases ?

In this case we can use this command to resume replication for all databases on specific server:

get-mailboxdatabasecopystatus -server “server_name” | resume-mailboxdatabasecopy

Also for suspending replication we can use this command:

get-mailboxdatabasecopystatus -server “server_name” | suspend-mailboxdatabasecopy

Each administrator of the Microsoft Exchange Server had certainly met or will meet with a situation where you have to find a specific email in the mailboxes, and sometimes even remove it.

In Microsoft Exchange 2010 to search mailboxes, we can successfully use the Search-Mailbox command.

But first make sure that we can run the command Mailbox-Search and
New-MailboxImportRequest.
If you try to run the New-MailboxImportRequest and reveive the message:

 “The term ‘New-MailboxImportRequest’ is not recognized as the name of a cmdlet”

 

This means that we do not have appropriate access rights.

Giving the appropriate permissions:

In Active Directory, create a universal security group such ExchangeImportExport_Allowed

As is known, together with new versions of Microsoft Exchange are changing also limits the number of elements in a single folder mailbox.

For each version of Exchange, Microsoft recommends not to exceed the following values of the number of items in the folder:
