16gb Limit - Just A RUMOR!?

Can anyone confirm this?


According to this Microsoft Document, the 16gb limit of the Information store hasn't existed since the release candidates (betas) of Exchange 5.5! I have seen many people talk about the 16gb limit, and the necessity to upgrade to the more exspensive Enterprise Edition.

Some other Microsoft documents clearly state a 16 gb limit exists in the size of stores of 5.5 Standard Edition.

I wonder if many of the CD's distributed as 5.5 final were actually Candidate versions. (For example, the CDs distributed immediately after release to upper-tier customers like MS Solution Providers and MSDN subscribers) I have seen before where my MSDN apps that claim to be final are different than the versions I download from MS after they become available online few days later. (Usually it's impossible to tell except that they are different at the binary level. Exact same version stamp, exact same language codepage, but a different size or CRC.) Is that what they did here? The only way to confirm this for sure will be if someone has a 16+ gig store and 5.5 Standard.
 
I think the limit exists, because our admins had to install enterprise edition after our system reaches the 16GB limit last summer. The email-server were stopped for 4 hours......
 
There is a 16 gigabyte limit on the standard edition ot MS Exchange server. The enterprise edition has a limit of many thousands of terabytes.
 
The web page pointed to at Microsoft says this concerning the 16gig limit...

"This problem was corrected in the regular version of Exchange Server 5.5. If you are still running the RC1 version, you must upgrade to the regular version to fix this problem."

Is "regular version" the same as standard edition?

I am interested in this too, as my database is will probably reach 16gig next year, but we will never have any use for the other Enterprise edition fetures.
 
The question is why would MS put a limit on this? he answer is easy, If you have over 16 GB on 1 Information Store object it might cause a conflict and corrup A LOT of data MS is just protecting there assets, This is why they have developed Directory Replication.

Thanks to all who replied. I have basically decided that there is a functional limit of 16gb in the Standard edition. The single document I posted above is the ONLY place ANYWHERE where I have seen mention of the 16gb limit being lifted without the mention of the "Enterprise Edition". Perhaps the document is speaking about a bug in the RC1 version of the Enterprise Edition? I think it's just a misleading, poorly written technote.

GDX is probably on the right track. But in my searching I found the most likly explaination. NTFS was originally designed with a 16gb file size limit. This limit was increased by NT SP3.
