Exchange active syncthis is worthwhile alternative. I have managed to set up the Exchange Active sync and the client is able to sync through GRPS successfully. However the only way to make sure they are getting new emails/calendar/task items is to set the O2 to sync every five minutes (this might not sound like a problem however they continue to compare it against the Blackberry where the direct push technology works perfectly). The “When items arrive†feature isn’t very reliable, it sometimes works and other times doesn’t. From what I understand it should force a sync if it notices a change within the Microsoft Exchange mailbox. The site is behind an ISA 2004 SP2 firewall and is running Microsoft Exchange 2003 SP2. Has anybody else experienced the same problem or could offer some solutions? Thanks in advance. I'm not familiar with the O2. Is it running Windows Mobile 5 with the MSFP?
If so, does direct push work for a while and then stop working? -- Show quoteJim McBee Blog: http://mostlyexchange.blogspot.com Free eBook: http://nexus.realtimepublishers.com/ttgsm.htm "BENWA" <BE***@discussions.microsoft.com> wrote in message news:AF3FF926-A196-4BBF-9922-94EAE756EB43@microsoft.com... >I have purchased an O2 Atom for a client who uses Blackberry's to see >whether > this is worthwhile alternative. > > I have managed to set up the Exchange Active sync and the client is able > to > sync through GRPS successfully.

KB 905013: Enterprise firewall configuration for Exchange ActiveSync Direct Push Technology http://support.microsoft.com/?kbid=905013 Look at the part about changing the timeout value on your firewall. Microsoft recommends setting the timeout value for HTTP(S) parameter on your firewall 15 minutes, but I have heard of people setting it as high as 25 - 30 minutes. -- Show quoteJim McBee Blog: http://mostlyexchange.blogspot.com Free eBook: http://nexus.realtimepublishers.com/ttgsm.htm "BENWA" <BE***@discussions.microsoft.com> wrote in message news:E6234618-3378-4F5F-BDC9-68DC3B8368DD@microsoft.com... > Yes it is.
