Hi , I have Exchange Server 2007 and I am running into a strange problem. I dont want one of my user to change his password from OWA so I went to EMS and executed Set-CASMailbox cmdlet and changed theOWAChangePasswordEnabled to false.Problem is that it has disabled all the other OWA features as well. Why is that so?Any help ????

Hi Athar, There is a trick, you need to change the value of a attribute called msExchMailboxFolderSet with ADSIEdit.msc. Refer below article for further detail. A funny Exchange Cmdlet, and how to fix it: Set-CASMailbox http://www.proexchange.be/modules.php?name=News&file=article&sid=1025

Hello Athar Muhammad,The reason is when you use the EMS cmdlet Set-CASMailbox to configure user-based segmentation for Outlook Web Access, even though you set the value of just one property to $False Exchange will set the value of all properties starting with OWA to $False, thereby disabling almost every feature of Outlook Web Access for that user or the users you selected to change.When you check the properties of the mailbox using AdsiEdit, you can see that by running the Set-CASMailbox cmdlet, Exchange has changed the value of the attribute msExchMailboxFolderSet.msExchMailboxFolderSet actually stores the segmentation settings for a mailbox-enabled user in AD. Depending on the features that are enabled and disabled, this attribute will have a different value. By default this value is not set for a user, when all features are disabled, the value will be 0.So, In order to disable one feature, it's very useful to first use AdsiEdit. set the value of MsExchMailboxFolderSet to 2147483647 then use the Set-CASMailbox cmdlet to disable the one feature wanted.Please have a look into this post, it explains almost everything about it.ReferencesA funny Exchange Cmdlet, and how to fix it: Set-CASMailbox on ProExchange.behope this helps
