iPhone not connecting to MS Exchange server

I have noticed that certain iPhones at our office have difficulty connecting to our Exchange email server. Same configuration is used for the Android phones and they seem to be OK all the time.

Anyone have any hints?

I administer ~50 iPhone/iPad devices connecting to the SBS Exchange.
I have not experienced any problems you mention.
What is the difficulty ? Are you getting errors connecting ? Are they connecting through WIFI or G3 or other network.
Obviously all OS is same on ALL devices right?

I am not the administrator for that side of the house. But, what I have seen them struggle with is when the Exchange configs ( are put in the iPhone settings and then the users put in their login name and password it sometimes takes a number of times to connect and some times they have to reboot the iPhone multiple times. I can not be sure on whether they are all running the same iOS, but I could check. There are no errors it is just that the iPhone can not connect to Exchange.

The connection type that I have seen is thru G3.

So, make sure all iOS is the latest. It may be that G3 is running slow or possibly your exchange server takes too long to respond or some combination thereof.

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

I will check that on Mon. Question: in your environment do you have Android phones as well? If yes, is the setup the same for both; iOS and Android?

Also, do you use SSL?

Our system admins have things under control. The issue was with WiFi reception. Thank you for the comments as they were helpful.

WiFi reception was poor. Relocated to better reception area and things worked just fine.
