*rofl*
Thanks MBS - that's exactly what I thought, and I agree with you about
the customer focus. The owners finally see it, but it took 2 people 7
hrs a day for 30 days to do the export from our in house mail server
when we outsourced, I don't see any way to get our mail back.
I agree about the cross forest - heck, I've done it myself before we
outsourced, I think our ASP wants to just 'redo everything' and take a
clean slate.
What's ironic is that I spend more time now opening tickets than I did
before outsourcing just fixing issues (blackberry out of sync, etc).

MBS is so into this stuff, he drives the new Saturn Outlook.

Let's not go comparing apples and oranges.
What Outlook reports on the client side is different than what ExPTA
reports on the server side. An Outlook-reported latency of 2500 ms is
far different than an ExPTA reported latency of 100 ms. If ExPTA is
reporting 100 ms or higher LDAP latency for more than 10 minutes, then
your provider has a serious AD slowdown (for example, OpsMgr reports
that as a critical failure, 50 ms or higher LDAP latency for more than
10 minutes is reported as "yellow" - potential problem). ExPTA should
see 20 ms or lower on average for LDAP lookups.
Exchange expects drive latencies to also average 20 ms. 226 ms is an
indication of a very overworked drive and may be an indication of a
poorly designed storage subsystem.
Now, in terms of "archiving"; if you want, you can do that yourself -
create a folder and move items to it. All you want to ensure is that
items are not in the critical folders, as I mentioned earlier.
Next, if they are telling you that, in the same data-center, they have
to do an export-import operation to move mailboxes to a new server, they
are just blowing smoke up your as...well, you get the idea. Move-mailbox
wizard works just fine cross-forest as long as you have name resolution
and all ports open.
Exchange 2007 with sp1 has I/O improvements that AVERAGE between 400% -
800% improvement (depending on usage patterns). Just moving to Exchange
2007 could potentially make all your performance problems disappear.
Sounds to me like your ASP isn't very customer focused. It might be time
to look at a new one.

Thanks Michael - so I assume this applies to both public folders as well
as individual mailboxes (as some of the KB articles implied Public
folders, although it didn't exclude mailboxes of course).
I did a search on 'mailbox size' and didn't get any hits, but I didn't
read all of the list, I have to admit.
In our case, we can't upgrade so far - the ISP is saying that to go to
2007 we have to agree to a 2G limit for all mailboxes. So this isn't
practical unless they change their policy. To do the upgrade, they want
to migrate everyone to a different AD forrest, so it's an import /
export for them.
Regarding our current server,
I'm surprised that 2500ms directory access is OK, that seems high.
Maybe I shouldn't worry about it then. The ExPTA didn't like it:
The maximum value of 'MSExchangeDSAccess Domain
Controllers(DS005.somewhere.local)\LDAP Search Time' is beyond the error
threshold of 100 ms. The measured value is 437.67 ms.
The average value of 'MSExchangeDSAccess Domain
Controllers(DS001.somewhere.local)\LDAP Search Time' is beyond the error
threshold of 50 ms. The measured value is 154.17 ms.
(etc ... for 5 directory servers)
Drive latencies are high also:
SMTP drive: Maximum '\LogicalDisk(C:)\Avg. Disk sec/Write' should be
less than 50 (0.05 ms). The measured maximum value is 0.226 (226 ms).
Our ASP doesn't offer any kind of online archiving, which would make
this all much easier.
