I'm in the planning stage of moving a company from a problematic pop3 email provider to 365 Business Email (365 Exchange)

They only have ADSL, no fibre available and I assume no VDSL available
~Modem~ dsl connects at 10M down, .8M up .
ADSL Speedtests this morning were so slow it often timing out due to internet speed issues , if speedtest finishes the upload speed is so low its unusable.
Shutting down all the PC's & restarting the dsl router bought the speedtest back up to approx .6Mbs upload .

So , the question is , at what stage do would you say the internet is just too slow to move emails to 365 ?
Email Downloads shouldnt be an issue, but email send & sync could be when (available) upload speed drops too low.
On the other hand, their current email setup has to send anyway, so would it really make no difference if they used current smtp or move to 365

Is ADSL just really too slow in general for 365 exchange for approx 10 users ? Either way , they need to change email provider .

Not knowing the business and the types of emails that are getting sent its really difficult to answer this!

If they're firing around big attachments then yep that upload is going to constantly hurt them. And if they're like most email users they'll be over using email and sending all kinds of junk around to each other (rather than walking up and having a chat).

You do have a benefit with O365 vs Pop in that you can use the web client which might help to alleviate a few of the issues (more around receiving emails than anything).

either way they need to get internet usage under tighter control , incl wifi access.
My guess is this morning something or someone out there was hogging all the bandwidth , fixed by restarting everything .

Im still unsure if 10 365 exchange users is going to be too much for their dsl upload speed . I'd hate to have them
commit to the 1 years 365 and then find its too laggy on their ADSL .
Wont know untill we try ?

does 365 buseness's "annual commitment" lock them into just a single lic for a year, or are the 10 additional licenses they need also committed for a year ?

I would think that that is only enough bandwidth for an on-premises solution, and barely enough at that.
I'd say the only way to run a cloudy business with ten seats and that little bandwidth would be going fully Thin, with all the processing done 'in the cloud'.

Would a wireless RBI-type solution give enough GB/month? How much are they using a.t.m.?

Have you checked if there's a local WISP who could provide even a 10/10 solution?

Edit: grammar

Where are they based? Do they have 4G available?

They are rural .
Looks like Wireless internet might be an option , according to address check on some ISP's pages .

They also have offices in other regions , but only 3 users in those offices so those shouldnt be as big an issue.
Also sales reps , out on the road. They would have to hotspot the phone or use local internet .

Over 20 users all up that would need a 365 lic , so having to spend even more $ on wireless internet in the main office
would be unwelcome news .

Either 4G or point to point if possible. ADSL won't be a good experience.

would it be any worse than what they currently use for email (pop/smtp)
Or would the extra overhead for 365 exchange push things over the cliff ?

POP works differently to 365.

This might help: https://www.geekzone.co.nz/forums.asp?forumid=49&topicid=255647

You assume, but have you checked?

I have a different scenario, but also for a rural connection. The 3G/4G connection is just not stable enough. That is why I am investigating the Business Satellite Unlimited plan from https://wirelessnation.co.nz/business/broadband-plans/

Yes, I have since checked :-)
Its rural , so not a big surprise
Online checks arnt 100% accurate anyway

Also, since they only get 1/2 the possible ADSL connect speed (distance from exch + line quality) , I'd assume that VDSL just wouldnt work at that site anyway (untill proved otherwise)

If you only getting around 10Mb/s down, and assuming premise wiring is ok, then that would suggest its way too long to try VDSL, definitely try a WISP

Ive recommended they go to wireless internet.
They have thought about "moving to the cloud" for their business apps , but thats a far off dream with the state of things .

Looks like they are going to go to 365 regardless .
Worst case they can use Webmail or just pop3/smtp connect to 365 .

Hi, yes with outlook web client or outlook app using MAPI over HTTP/HTTPS which outlook will connect to 365 to by default please not pop/smtp.

Typically I recommend 1/2meg in available bandwidth per user. So your download is likely OK, but your 0.8 upload is going to kill your usability and will be unsuitable. Fix the internet connection first.

Outlook can also be configured to download the X days/weeks/months of mail, so configure this as well. Everyone downloading there mailbox on day 1 can also kill your internet connection.

Realistically 365 would be the same as on-premises in terms of bandwidth, majority of emails should leave the organisation so they're subject to the same constraints regardless of hosting solution. I have had a similar number of customers running email in 365 off ADSL with a slightly better upload speed, where it ground to a halt was when they also decided to drop SBS and move to SharePoint on the same circuit.

Your main issue will be the migration of the customer to Office 365 if the upload is spotty, you'll likely need to look at a PST export and do a great job of policing up all the emails. You can do a PST import into 365 from a location with better internet then a delta PST export when you cut them over to 365 to pick up any new emails during the migration phase. If your download is good then this should be fine. There should also be some 3rd party tools to help with the migration from POP although I think most of them require PST exports.
