Disable or Remove Mailbox in Exchange 2010

Disable: will remove the Exchange attributes for the user account but leave the user account in Active Directory. The mailbox is then also left in the Exchange mailbox database until the retention period (30 Days) has passed, then it is removed permanently.

Remove: will remove both the Exchange mailbox and the user account from Active Directory.

Note: Disable is the safest option, because you can quickly reconnect the mailbox to the user again if it is still within the retention period.

WSUS Content Folder is Full

Problem:

You’ve run out of space on your server and you find out that the WSUS Content Folder is full and it’s eating up space. The WSUS is Windows idea of a centralized update service. In theory, it downloads all the updates for your environment and then distributes them. It does not do a good job of cleaning itself up (consider the manual wizard cleanup) and it comes preconfigured to download the updates for all Windows products, not just the ones you need. As well, when you run the Cleanup Wizard, the console crashes.

Solution:

1. Open up WSUS Console
2. Go to options and only select the updates for the products you need

 

How to Do a Reset:

Note: You may want to execute the procedure below during off hours as your WSUS server will be downloading quite a bit of data.

1. Close any open WSUS consoles.
2. Go to Administrative Tools – Services and STOP the Update Services service.
3. In Windows Explorer browse to the WSUSContent folder (typically D:\WSUS\WSUSContent or C:\WSUS\WSUSContent)
4. Delete ALL the files and folders in the WSUSContent folder.
5. Go to Administrative Tools – Services and START the Update Services service.
6. Open a command prompt and navigate to the folder: C:\Program Files\Update Services\Tools.
7. Run the command WSUSUtil.exe RESET

This command tells WSUS to check each update in the database, and verify that the content is present in the WSUSContent folder. As it finds that the content is not present in the folder, it executes a BITS job to download the content from Microsoft. This process takes quite a bit of time and runs in the background.

What is Circular Logging?

Circular logging is a method of conserving hard disk space in the Microsoft Exchange Transactional Logging process. It works by overwriting individual log files to keep the transactional log (the set of all log files) from expanding without limit on the hard disk.

When circular logging is disabled, every single log file goes into the transactional log database, and no limit exists as to how large that database can get. When circular logging is enabled, however, the transactional log can only grow to one megabyte (1 MB) in size. After that limit has been reached, the first log file is overwritten automatically to keep the transactional log database from growing any larger. The term « circular » arises from the fact that the set of log files starts to « rotate » once the disk space limit is reached, something like a LIFO (last-in, first-out) queue.

Circular logging is commonly used with Exchange native data protection, because in that mode, backups are not made so a detailed transactional log is not necessary. Circular logging is disabled by default in Exchange 2010. That’s because, if circular logging has been enabled and the database becomes corrupted or otherwise compromised, it cannot be completely recovered if data has been added more recently than the time that the last full backup was created.

Exchange Server 2013

So, what’s new in Exchange Server 2013?

The new features and functionalities include:

Session Indifference: In Exchange 2013, the client access and mailbox components reside on the same Mailbox server and no session affinity is required at the Client Access servers. This allows inbound connections to Client Access servers to be balanced using the techniques provided by load balancing technology such as round-robin and least connection.

Unified Messaging: Unified Messaging in Exchange 2013 contains essentially the same voice mail features included in Exchange 2010. Certain new and enhanced features have also been added to the existing features. Exchange 2013 integrates with SharePoint 2013 to allow users to collaborate more effectively. OAuth authentication lets partner applications to authenticate as a service.

Anti-malware protection: The implicit malware filtering capability of Exchange 2013 helps protect your network from malicious software spreading through email messages. If malware is detected, the message is deleted. Notifications can also be sent to administrators when an infected message is deleted and not delivered.

Batch mailbox moves: This new move architecture is built on top of MRS (mailbox replication service) moves with advanced management capability. The features include:

    • Ability to move multiple mailboxes in large batches.
    • Email notification during move with reporting.
    • Automatic retry and prioritization of moves.
    • Periodic incremental syncs to migrate the changes.

Automatic recovery from storage failures: In addition to the Exchange 2010 bug check behavior, Exchange 2013 includes additional recovery behavior for long I/O times and excessive memory consumption.

Support for multiple databases per disk: Exchange 2013 includes enhancements that enable you to support multiple databases on the same disk.

Automatic reseed: This helps you to quickly restore database redundancy after disk failure. If a disk fails, the database copy stored on that disk is copied from the active database copy to a spare disk on the same server.

Managed Store: The newly rewritten Information Store processes in Exchange 2013 is known as Managed Store. This new Managed Store is written in C# and tightly integrated with the Microsoft Exchange Replication service to provide higher availability.
