shark_90 Posted October 28, 2008 Report Share Posted October 28, 2008 Just setting this up on the Mrs's iPhone. It says it's working but I'm not convinced.. if I go to the Mail icon at the bottom of the screen it does a quick sync and all of a sudden her mail's there, but it's not actually bleeping when the mail is sent (I've sent a few test mails). Anyone got any ideas? It says it's using Push in the settings area. Contact sync is working. Link to comment Share on other sites More sharing options...
Mac Posted October 28, 2008 Report Share Posted October 28, 2008 I'm using it and you're right - it doesn't *always* push immediately, but it will come through. I'd also say when you first set it up it takes a while to get its knickers straight. Link to comment Share on other sites More sharing options...
shark_90 Posted October 28, 2008 Author Report Share Posted October 28, 2008 Fair enough mate, I'll stop being so fecking impatient then Link to comment Share on other sites More sharing options...
Mac Posted October 28, 2008 Report Share Posted October 28, 2008 Also, push won't work if your exchange provider is not using a publicly trusted SSL cert. Link to comment Share on other sites More sharing options...
shark_90 Posted October 28, 2008 Author Report Share Posted October 28, 2008 Using self signed cert here and it's allowed me to set it up and it does think it's using Push. One email has gone through immediately as soon as I sent it. Seems a bit hit and miss though. Also replied no problem using the same (only) account.

Mac Posted October 28, 2008 Report Share Posted October 28, 2008 If it's self signed then push won't work - only pull will. Do you have schedules set for pull? Do you have Outlook Web Access? Is that secured with a self signed cert then :confused: Link to comment Share on other sites More sharing options...
Mac Posted October 28, 2008 Report Share Posted October 28, 2008 (edited) Thinking about it with a self-signed cert, I.e. untrusted, you don't have an MTLS connection at all - I'd be surprised it works at all? Also, make sure on the server you don't specify the http(s) prefix or the /owa suffix. Should JUST be the mail server such as mail.domain.com. Also, you need to check the default timeout on your IIS server that's hosting your mail. If it's on the default it's probably too short and you'll have intermittant delivery. Push email is a bit of a fudge in that it relies on slow internet protocols to hold open connections and receive email.

shark_90 Posted October 28, 2008 Author Report Share Posted October 28, 2008 No schedules - the iPhone thinks it's set up to push, really it does! Already sussed the server names/setup etc. It appears to work. I think! Will have a look at the timeout. Link to comment Share on other sites More sharing options...
Mac Posted October 28, 2008 Report Share Posted October 28, 2008 Cool The timeout problem can give you random delivery times etc. It's worse as some firewalls won't actually permit the ICMP close message across the the device doesn't know it's connection has been closed. In that case it eventually cycles and you get the random delivery affect. It amazes me that 'push' technology works as well as it does as it affectively abuses the weakness of IP based connectivity - well it does on Exchange anyway, BES is a little bit more robust.

chasdrury Posted October 29, 2008 Report Share Posted October 29, 2008 My Exchange Direct Push works with a self cert - at least I assume it's self cert since I didn't certify it anywhere publicly! Link to comment Share on other sites More sharing options...
