Literally 20 concurrent users? (not 20 users, who in reality might induce about 2 simultaneous accesses?)

I'm not sure to be certain. If you really need 20 concurrent sessions I'd probably be looking at at least 2Mbps upstream from your server - maybe more. 1Mbps might suffice. Depends how responsive you want the service to be and how well the server can even cope with this kind of use.

Not necessarily 20 concurrently, but there could be the possiblity of that many at once,
Are there any isp's that offer plans with 1Mbps+ upstream?

All ADSL2+ plans I'm aware off are 24000/1024Kbps. The download speed is affected by distance, but not upload speed so much.

Keep in mind that even with 20 users concurrently logged in to OWA, it's unfathomably unlikely that they'd all request something at the same moment.

At work, we have OWA on our exchange/IIS server and we only have ADSL1 (8000/384). We rarely get enough traffice to stress out the connection, mainly because it's rare to get more than one using OWA at the same time.

I assume this is for a business? How important is it to the business?

If the answers are yes and "at least somewhat" then I'd strongly recommend both:

1) Going for SHDSL (1/2/4Mbps) on a business or small-business plan - this will provide an availability guarantee and a speed guarantee - none of this 'hope for the best' ADSL crap... and

2) Sign up with a reputable ISP with a track record of providing a stable service with good support. We use both Westnet and Internode for SHDSL services (and ADSL services also) and have found them very accommodating to our requirements.

If this is a business, don't cheap out on the dodo/tpg/somelongwang super-express 200TB ADSL2+ plan for $29.99 per month.

Internode and perhaps others offer Annex M or something which takes a bit away from the download speed and gives it to the upload speed, for a theoretical maximum upload speed of about 2.5Mbps I think. Someone correct me if I am wrong.

Its actually for a business with multiple store locations and a head office, not a big company so money is an issue to a degree, thus the
reason for OWA and not having outlook in all locations.
There will be some stages were most will need to be logged to recive reports etc, close to the same time.

I normaly recommend exetel for bussiness, as they do provide good services and good pricing, and there quite good for corporate setups.

But all the plan speeds still confuse the crap out of me.
Sorry if thi seems like a really dumb question but i want to get this straight. I have a 8192kbps Down/384 kbps Up connection. Now is that 0.8192MB/s down / 0.0384MB/s UP ?

An 8192/384 ADSL connection will at beat achieve 8 Megabits/second down, 0.38 Megabit/second up - and for that you need to be quite close to the exchange.

That's approx bandwidth 800 kbytes/second down, and 38 kBytes/sec up.

I'd not recommend that sort of connection for any corporate webserving of consequence unless you're expecting you users to all be coming in on dialup/2G mobile connections. With that would be the implication that it would be unsuitable for webmail where large attachments were expected.

Annex M plans are not that expensive by corporate standards if you can get them. A $80/month plan may be more than enough to run the head office - assuming it's in a location that supports it and is close enough to the exchange to offer reasonable bandwidth.

Just remember ADSL (whether 1, 2 or 2+) has no speed guarantee - SHDSL does. And SHDSL usually has an availability guarantee - ADSL doesn't.

Yeah thats was more of an off topic question, i wasn't planing to run it on that particular connection.
Some developments have come about and pricing may not be an issue anymore, so ill be looking towards a SHDSL connection.
I think ill do some practical testing first, just get some friends an whatnot to play around on it and see what sort off bandwidth they pull.
Thanks for your help.
