iphone exchange calendar not syncing when connected to office wifi

If I connect to the office wifi and add an appointment to my calendar, my iphone does not see that appointment.  If I turn the wifi of and use 3G, the appointment shows.  If appears that I can only sync with Exchange if I am on 3G or another wifi besides the one in the office.

The internal DNS is most likely not allowing the resolution of the full domain name you are using on the iPhone to connect to the exchange database ... i.e. - externally you connect to exchange.mycompany.com and internally that does not resolve from DNS on the server, you need to add the internal A Record to your DNS tables to resolve that IP to the correct internal ip address.

I follow the instruction in the article but it did not work.  I don't know if my iphone setup may be wrong.  I have my server as an ip address xx.xx.xxx.xx.  Then I have my domain name in the domain box.  Does this sound correct.

Alan HardistyCo-OwnerCommented:
You can't use an IP address to connect because your phone can't resolve that internally.  If you were using a Fully Qualified Domain Name, then not a problem.

What is the reason for using an IP address?

I inherited this setup.  If I am outside of the office and I want to look at outlook on the web, I type in my ip address.  Since there is no domain name registered, how else would I get to the server?

Alan HardistyCo-OwnerCommented:
If you din't have a domain name registered, is email only for internal use?

Why not register a domain? Simple, cheap and then you can configure your phone and make it work happily.

Maybe I am not understanding the setup.  We have a company website and external email.  I haven't been able to find any documentation on setting OWA up using my external domain name.  Do you have a link or something that will help.

Where is your website pointing and how do you get mail to your server?
0
egalawAuthor Commented:
Our website points to dns servers where it is hosted.  Email is downloaded to each computer individually.  It does not go through the exchange server.

Alan HardistyCo-OwnerCommented:
Okay - so you have a domain name at least. Why does mail not get delivered to the Exchange server?

What are you configuring the iPhone for to sync with Exchange if not for emails?

egalawAuthor Commented:
We are configuring iPhone to sync with exchange for email and calendars.  Our exchange server does not retrieve our pop mail.  That is done individually at the few users in the company with outside email.  The iPhone is setup to get the mail from the exchange server.  Individual computers with Outlook retrieve the pop mail which is then stored on the exchange server.  This was the setup before I started working here.  I only have enough exchange knowledge to keep things running.  I am sure there are better setups but this is what I have to work with.

Alan HardistyCo-OwnerCommented:
You would be far better off letting Exchange receive your email not the PCs and then configure Outlook to connect to the Exchange server to get the emails.

As it currently stands, Outlook would have to be open for a phone to receive any emails which is bonkers.

If you want some assistance getting things setup in a more conventional way, I am happy to help you, then you can work more efficiently and smoothly.

That would be great.  I know the setup we have isn't correct but it is working.  Would Exchange check a catch all box or would it retrieve pop mail for each individual mailbox?
0
Alan HardistyCo-OwnerCommented:
Exchange would receive mail directly and if an email address didn't exist that an email was sent for, then the message would be rejected.

A catch-all account would be a bad idea as all it will achieve is increasing your spam.

Mail would arrive automatically in your server - no POP3 processes involved at all.

I appreciate the help.  What information do you need from me to get my setup corrected?
0
Alan HardistyCo-OwnerCommented:
You are welcome.

Initial step is to determine if you have access / control of your domain name.

If you could tell me your domain name, then I can check what is needed and give you specific advice, plus I can hide your domain name to protect your identity.

Thanks

Alan

Can I contact you directly?  There may be information that I don't want spread on the internet.

Alan HardistyCo-OwnerCommented:
Click on my name which will take you to my profile and my contact details are detailed there.

We need to keep this thread updated with anything that we do, so communication should continue to take place on EE, but passing of sensitive info by email should be fine if you are not comfortable posting it on site.
