Did you now pop3 settings of Exchange 2007/2010 will be stored in AD?

Exchange 2010 schema prep fails when Exchange 2007 SP3 is installed

According to the Technet documentation you should be able to install Exchange 2010 in an environment where Exchange 2007 is running. A while ago I got a question from a customer who had an issue when trying to install Exchange 2010. The problem occured running the setup.com /ps to extend the schema for Exchange, the following error message was displayed:

Exchange 2007 Service Pack 3: changing your password

One of the new features in Exchange 2007 Service Pack 3 is the ability for users to change their password before logging in. Before service pack 3 a user who’s password had expired needed to call the helpdesk to reset their password or use another solution. With this new feature a user will be redirected to another page where he/she can change the password.

During a cross-forest test migration from Exchange 2003 to Exchange 2010 I got the following error:

Open another users calender via OWA

Opening a calender from another user using OWA is not a very hard proces, when you have enough permissions you can easily open the other users calender. But what if you would like to do this via OWA?  This depends on the Exchange version you are using, let’s start with Exchange 2003:

Microsoft releases security updates for Exchange

Microsoft has released security updates for Exchange 2000 SP3, Exchange 2003 SP2, Exchange 2007 SP1/SP2 and Exchange 2010. For both Exchange 2007 and 2010 this security fix is  included in a rollup. For Exchange 2007 SP1 this is the 10th rollup, for Exchange 2007 the 4th and for Exchange 2010 the 3rd.

Get-owavirtualdirectory does not return all CAS servers

By accident I found a bug in Exchange 2010. The issue only occurs in Exchange 2010 and if you have multiple CAS servers which are located in different sites and can’t communicate to eachother. Till now I only saw the issue with Exchange 2010 where an extra CAS server was added to the mainoffice. In this case this is the 3rd CAS server in the Exchange 2010 environment
