Exchange 2010 RC

Microsoft has released Exchange 2010 Release Candidate today. The release candidate is available as VHD and as installable version. The release candidate can be installed on both Windows 2008 and Windows 2008 R2. With this Exchange 2010 will be the only version of Exchange which is supported to run on Windows 2008 R2 for now. Several sources report that Exchange 2007 will not be supported on Windows  2008 R2, even when service pack 2 will be available.

Steps to perform before installing a Rollup

Install a rollup for Exchange, that’s the way it goes most times. But in some cases it can go wrong, OWA doesn’t work anymore after an upgrade is an example of this. To prevent this from happening Amit Tank (MVP Exchange) wrote an article where he explains which steps to be performed before installing the rollup. Besides this he also explains which logs are created in case you need to troubleshoot an issue.

OWA doesn’t work after installing Rollup

On several forums you will see that installing a rollup can break down OWA. One of the issues you can have is that a blank screen will be presented with in the url reason 0 as a parameter.

Exchange and using the ä in an e-mail address

Last week I found a nice issue on a forum. A user who managed an Exchange server in a Scandinavian country had issues with using the letter ä in an e-mail address. When a user had this name the e-mail address was generated with an ae instead of the ä.

A while ago …

It has been a while but since this week I am back online thanks to my neighbour.  My own provider hasn’t been able to arrange the new connection despite several phone calls and a letter which mentioned the line should be working on 21-7.

Exchange 2007 shared address space

Sometimes you will find the situation having several types of mailservers within one organization, for example Exchange in combination with another mailserver. But how can you arrange that Exchange will accept the mail, checks if the recipient exists on the Exchange server and if not will forward it to the other mailserver.

Congratulations 2009 Microsoft MVP!

Exchange 2007 uses MX record even is sending via a smarthost

Normally when using a smarthost you wouldn’t expect that the mailserver does a query for the MX record in DNS. Well it does in Exchange 2007 and Exchange 2010. A while ago I found a post on Technet from someone from Microsoft who mentioned this. I found it pretty weird so I thought let’s test it. And indeed when using a smarthost and making a networktrace you will find out that it does a query for the MX record in DNS.

User alias is incorrectly displayed in the to field in Outlook

This week I had a strange issue but I was able to solve it. There were some serious issues with a user and the only solution was to recreate the user-account. On first sight no problem you will need to trick somethings but it will work. After recreating the user I reconnect the old mailbox and it looked OK.

Can’t mount Exchange Database: error 0xfffff764

It doesn’t happen daily that one or more databases will get corrupt in your Exchange 2003 environment and can’t be mounted anymore. But it can happen when for example a database will not be shutdown normally which can be caused by a systemcrash.
