Fwd: Re: Stable Kontact client for Kolab3

[JCollet]

Hi Geoff, Just like the member from Australia, I must disagree with your basis
for this argument. I'm not doubting your qualifications but I do call into
question your knowledge of Outlook. I do manage 1000s Outlook accounts and was
forced to become proficient in it. The facts aren't unfortunately how our
customers want to use Outlook but how it was designed and what its native
limitations are:
- It's not an OST or PST issue, the OST file has to get really big before the
OST can't properly handle its own large OST file which is the same for the PST
file.
-Most importantly, it's dictated by whether  you're using 32 bit or 64 bit.
According to MS, 32 bit can only handle up to 2GB, that's the limit for 32 bit
address space.  64 bit is way bigger than 2 GB (into the TBs). I must deduce
that you're using 32 bit. I have users with 25GB using Bynari connector, with 64
bit and no complaints there.
I hope this helps you with your 5GB customers.

John
