Mike,
We run into the same exact thing from time to time and there’s
no rhyme or reason to it, as you alluded to. We use Zenprise here and the techs
usually just reinstall the app or wipe the device and try again.Regards, Don Guyer Catholic Health East - Information Technology Enterprise Directory & Messaging Services 3805 West Chester Pike, Suite 100, Newtown Square, Pa 19073 email: dgu...@che.org<mailto:dgu...@che.org> Office: 610.550.3595 | Cell: 610.955.6528 | Fax: 610.271.9440 For immediate assistance, please open a Service Desk ticket or call the helpdesk @ 610-492-3839. [cid:image001.jpg@01CDB688.FCE7F580] From: Mike Tavares [mailto:miketava...@comcast.net] Sent: Monday, October 29, 2012 10:38 AM To: MS-Exchange Admin Issues Subject: ActiveSync Issue(s) For the last week or so I have been chasing my tail around in circles trying to figure this one out. The issue is I have roughly 400 activesync devices (IOS 4, 5, 6, All android versions, Blackberry Playbook and 1 palm device). A small number of IOS devices (using both iOS 5 and IOS 6) are randomly getting the error message cannot get mail, the connection to the server failed, and if they are not getting the error the connection to the server is extremely slow. This affects about 10 devices that I am aware of and sometimes all of them at the same time, sometimes just individual devices. (all different carriers) The exchange environment is Exchange 2007 (750 users). ISA (2006) server handling the ActiveSync Connections. 2 CAS Servers. OWA (goes through the ISA server as well) and Exchange itself seem to be working ok at the time these issues arise. The issue happens whether these devices are on wireless or the cellular network. Doesn’t happen at any consistent times. When the devices are not connecting at all I do not see any connection attempts on the issue. When the issue is slowness, I see the connection on the isa server and response is generally under 35ms, (varies depending on the size of the message it is syncing) so that tells me isa-exchange connection is ok (and all the other remaining devices are connected and syncing with no issues). For a while I thought the issue was an iOS 6 issue since they were 100% of the devices having the issues. But now I have 1 iOS 5 device having the same problem. I know with Exchange 2010 I could do some throttling to see that had any affect on the issue, but since I am still on 2007 I don’t have that ability. Not sure where to look, so I am looking for some ideas.
