Awaiting for this product from Microsoft is over, Communications Server 2010, also called Wave 14 – renamed to Microsoft Lync Server 2010. Microsoft has announced that the new 2010 edition has been released to manufacturing (RTM). The official launch event was on November 17th 2010, so I am sure now that those who have Software assurance, will be downloading now and preparing for the installation/migration.
Microsoft Lync Server 2010 communications software offers instant messaging (IM), presence, conferencing, and telephony solutions that can support enterprise-level collaboration requirements. This is only available in 64-bit edition , it requires 64-bit hardware and the 64-bit edition of the Windows Server operating system. Client computers does not required to have 64-bit hardware or software.
Features and capabilities of Microsoft Lync Server 2010 communications software clients in the following categories:
- Contacts and groups
- Instant messaging
- External user support
- Mobile access
- Archiving and compliance
- Publish your photo using sharepoint and others can view your pictures on their client
- Lync client can now join the Live meeting
- Administrative jobs have to be done through Microsoft Lync Shell Command
- Basic configurations through web control panel
- Branch office resilency call route feature
- Virtualized topology of Microsoft Lync Server 2010
- Active Directory for storing Lync server configurtaion has been moved into a new database server Central Management Server which hosts Central Management Store db. in SQL…but some of the info like SIP URI and phone numbers are still in AD.
- Mediation Server can route calls to Multiple Gateways..sounds nice
- The Lync clients can now be directly updated using windows software update service or windows update.
- ……more to go…i will update you over here
Most of the friends and collegues starts asking me the question about the difference between SSD and Flash Drive. I thought of writing this blog..so here it is
‘Flash Drives’ are a generic term which used for anything from USB memory sticks to SSDs. An USB flash drive uses lower quality low performance NAND flash with just 1 or 2 channels. Its durable, cheap but slow. An SSD on the other hand uses high performance NAND with mutliple channels. ( 12 or 8 is not uncommon), and there is a memory controller on a SSD which is much better and both can store data even if its not powered.
Flash drives (USB) are slow storage devices where as SSDs are high performance drives. They’re much faster than normal HDDs.
A USB flash drive uses USB, which is generally a slower interface than the Serial ATA interface. A USB flash drive is generally thought of as a removable device by the OS and is managed as such. A SSD is treated similarly to a hard drive, and is often recognized by your OS as a type of fixed disk.
USB flash drives and solid-state drives are both based on flash memory. Most of the flash memory use NAND memory, which are available as single-level cells (SLC) and multi-level cells (MLC). Single-level cells store a single bit in a single memory cell, whereas multi-level cells store more than a single bit in a single memory cell. The MLC accomplishes this by allowing each memory cell to store multiple electrical states, therefore, allow one MLC cell to store more information than one SLC cell. For example, a MLC that uses 4-levels can store 2 bits of information. MLC are cheaper, as they can store more information per memory cell than SLC. Cheap, large SSDs and USB flash memory use MLC disks, although not necessarily. MLCs sounds great in terms of storage density, but it does have a catch. MLCs are slower than SLC. Therefore, the large capacity USB flash drives and SSDs tend to be slower. Solid-State Drives (SSDs) have no moving parts, high reliability and longer life-span than traditional hard drives
One of the example of SSD is Intel X25-E Extreme SATA Solid State Drive

In the previous edition of OWA and Exchange server 2007, there was a problem for users to change their password…because the loss of the IISADMPWD virtual directory as a supported feature in Windows Server 2008/IIS 7.0. This prevented OWA users with expired passwords from being able to change their password and log on. This was a problem for many OWA users ; especially remote/mobile users with non-domain-joined computers..From Exchange Server 2010 Service Pack 1 and Exchange Server 2007 Service Pack 3 (running on Windows Server 2008 or Windows Server 2008 R2) onwards, they have a new feature that will allow users with expired passwords to change their password. This also works for users who have their accounts configured to change password on next logon.
Use this procedure to enable it on Exchange 2007 SP3 and Exchange 2010 SP1 Client Access servers. If you are using a CAS Array, you must perform these steps on each CAS in the array.
- On the Client Access Server (CAS), click Start > Run and type regedit.exe and click OK.
- Navigate to HKLM\SYSTEM\CurrentControlSet\Services\MSExchange OWA.
- Right click the MSExchange OWA key and click New > DWord (32-bit).
- The DWORD value name is ChangeExpiredPasswordEnabled and set the value to 1.
Note: The values accepted are 1 (or any non-zero value) for “Enabled” or 0 or blank / not present for “Disabled”
- After you configure this DWORD value, you must reset IIS. The recommended method to reset IIS is to use IISReset /noforce from a command prompt.
NOTE : User can’t use a User Principal Name (UPN) (eg: firstname.lastname@example.org) in the Domain\user name field in the Change Password window like below. It should be domain\myname
Once you done with it, click submit…make sure that your new password should match with the domain password policy.
Even if you delete item from the deleted items from your outlook 2010, you can go to the tab under folder on the main page of the outlook 2010 and click “Recover Deleted Item” and view the items on the list
MailTips are informative messages displayed to users while they compose a message. Works with only Exchange server 2010 with Outlook 2007/2010.
Microsoft Exchange Server 2010 analyzes the message, including the list of recipients to which it’s addressed. If a potential problem is detected, MailTips notify users prior to sending the message. With the help of the information provided by MailTips, senders can adjust the message they are composing to avoid undesirable situations or non-delivery reports (NDRs).
You can’t use the EMC to enable or disable MailTips. You need to be assigned permissions before you can perform this procedure. To see what permissions you need, click here
EMS : Set-OrganizationConfig cmdlet to enable or disable MailTips in your organization. MailTips are enabled by default, when you install a new Exchange 2010 organization.
Examples of Mailtips, when you activate is like
- Invalid Internal Recipient : The Invalid Internal Recipient MailTip is displayed if the sender adds a recipient that appears to be internal to the organization but doesn’t exist in Active Directory. It comes due to name resolution cache or an entry in the sender’s Contacts or if the sender types an SMTP address with a domain for which Exchange is authoritative and the address doesn’t resolve to an existing recipient. The MailTip indicates the invalid recipient and gives the sender the option to remove the recipient from the message…cool na
- Mail Box full : MailTip is displayed if the sender adds a recipient whose mailbox is full and your organization has implemented a Prohibit Receive restriction for mailboxes over a specified size. MailTip will be updated every two hours in his/her draft folder even if you save it and did’nt send the message.
- External Recipients : The External Recipients MailTip is displayed if the sender adds a recipient that’s external, or adds a distribution group that contains external recipients. By default, this MailTip is turned off. You can turn it on using the Set-TransportConfig cmdlet. The External Recipients MailTip relies on group metrics data. Therefore, if you enable the External Recipients MailTip, make sure that the group metrics MailTip is also enabled. EMS : Set-OrganizationConfig -MailTipsExternalRecipientsTipsEnabled $true
