New and Updated list of Recommended fixes for Exchange 5.5

I have one machine that had it's hard drive fail 4 times in one month.  I guess that is a good reason for not posting in a while.  I thought this might make up for it.

Some of our customers are still running Exchange 5.5 even though mainstream support for the product will retire this year and extended support will retire next year (  So, this may be the last time I get to update this list.  Most of the hotfixes that are listed here are only available by calling Premier Support Services (PSS) at 1-800-936-3500 and asking for the fix. 

All of these fixes require Service Pack 4.

Remember that these fixes include fixes from the past as well, so even if the KB article doesn't mention a incident that may seem like that big of a deal to you, many times there were many other issues before fixed that are very important.  So, I would recommend that you stay up to date.

    That Store fix being removed from the download site is actually quite annoying, as it’s the one that is referred to as being required in site consolidation articles. In particular, this:;en-us;843104

    Perhaps someone could get the consolidation KB article updated, and point to the new fix?

    I agree. This should be fixed. Last night we did get the updated rollup available for download though. I’ll see if I can get the content people to update the other links though to point to the new link at
