Obtaining Exchange 2007 SP3 Update Rollup 23


I've inherited an Ex2007 server and looking to upgrade it to an interim Ex2013 then onwards to Ex2019 - but it's only updated to SP3 Rollup 21.  Microsoft have removed the page with the download for rollup 23 and this is a requirement I believe for upgrading to Ex2913

Does anyone have knowledge of a dowload location for this update?

I think we need to set up a repository for those old updates if Microsoft deletes them.

    I don't have a French version but did you try to install the version listed above?

    Yes i have try to install the english version but it doesn't work.
    The latest version I find in the update catalog is RU21 (KB3184711)

    OK, not nice! I don't have a solution for you. You may try a French forum? If nothing works you can migrate to EX2010 first with the current service pack and version, after that to EX2016. That is more work but I have done this before.

    Hi Jo

    I have Exchange 2007 SP3 CU23 but German Version only.

    Don´t think this will help you in French Version...


    I got help in Formu, there was huge interest on my post there,

    about 70 others were demanding CU23 for Exchange 2007.


    Maybe some there could help you.


    I tried MS Partner Support in Germany, but they dind´t help me in any way.
