No outgoing email after Exchange 2010 Service Pack 3 Rollup 1 installed

We like to keep our servers up to date so after testing in our VM environment we went ahead and installed the latest update rollup for Exchange server 2010 from Microsoft.

Everything went smoothly but afterwards we soon realised that no email was going out – no bounceback no message nothing, it just dissappeard!

It turned out to be a problem with out Disclaimer. Like most companies we add a disclaimer to every email sent outside the organisation. Because of this additional step on the server all these outgoing emails were seen as ‘poisoned’ and were dropped.

Obviously, this is something rather difficult to test for and after looking on a number of forums many Microsoft customers had suffered a similar fate.

Microsoft were looking into it and would be providing an update but in the meantime we had to turn off our disclaimer adding and ask out users to add them manually for now.

After opening a support call with Microsoft it transpired that a Hotfix was available. We downloaded, tested and rolled it out and disclaimers are now working. Please bear in mind that if you need to install a rollup in the future this Hotfix has to be uninstalled before proceeding.

In other words Microsoft won’t release a new update intil the next rollup despite the severity and will only supply a hotfix on request. Not very impressive.

Here is the relevant article and details of hwo to obtain the hotfix: http://support.microsoft.com/kb/2859596/en-gb
