Exchange Mail will not Send mail from Iphone when Desktop computer Shutdown

A client of mine has an Iphone that I have setup to connect to his Microsoft Exchange 2003 Server using Activesync. Everything works fine and dandy until he shutdown his desktop in his office. Than he is no longer able to send any mail from his Iphone but is able to receive it no problem. Anyone have any insight on this problem?

Your problem is with Cox and Cox not having an authenticated SMTP server.
Not many ISPs provide an authenticated SMTP server and I'm not sure why - especially with laptops and devices such as the iPhone so popular.
I'm a Time Warner/RoadRunner customer for cable and internet access and I quit using my RR email account several years ago for this very reason. I switched to using my .Mac account as my primary personal email account which has an authenticated SMTP server. I'm able to send messages with the account regardless the internet service provider used for internet access. My business POP account also has an authenticated SMTP server and no problems sending with this account either - via a number of different Wi-Fi connections and EDGE.
I suggest seriously considering switching to another email account. A Gmail account is free, can be accessed as a POP or IMAP account with the email client on your computer as well as with the iPhone's email client, has a good spam filter at the incoming mail server, and has an authenticated SMTP server.
If you ever move or decide to change your ISP from Cox to a different ISP, your email account and address will not need to change. You can access and send messages with a Gmail account with any ISP - the same with a .Mac account. And you'll have much more server storage space than Cox provides.

Mail will not send mail, only receive.

I have spent the majority of today re-installing OS X and all necessary updates, music, data after the death of a hard drive. Luckily everything went perfectly, except for the same problem I had with Mail even before the 1st hard drive died. Mail will not send mail, only receive.
All efforts time out and give me this message: "The connection to the server mail.earthlink.net on port 25 timed out"
Mail used to send messages, but stopped suddenly in 2004 and has yet to start again. Any idea guys?! I can't figure it out, under Account settings I have necessary fields filled in: Outgoing Mail Server (SMTP) is set to "mail.earthlink.net", Server Port is set to 25, and Authentication drop menu is set to None.
Any help would be greatly appreciated.

This is NOT a problem with Mail or OS X. This is an incorrect settings problem - garbage in = garbage out and this information is certainly available at Earthlink's website and Earthlink also provides technical support.
Earthlink has an authenticated SMTP server they changed to long ago.
SMTP Server: smtpauth.earthlink.net
Server Port: 587 but 25 should work if you are using Earthlink as your internet service provider for connecting to the internet.
Use SSL: Off or not selected.
Authentication: MD5 Challenge-Response
User Name: Your ENTIRE Earthlink email address.
Password: The account's password - the same password used to check the incoming mail server for new messages.

TS2621 E-mail will not send on Verizon iPhone 5

Internet provider is Cincinnati Bell. I can receive E-mail but not send it. iPhone 5 is on Verizon. I set up my E-mail on a relative's AT&T iPhone 5 and it worked fine. I called Verizon, but they think it is Cincinnati Bell problem, but this doesn't seem right to me because my E-mail works fine on an AT&T iPhone 5. Any suggestions?

Your issue is almost certainly the SMTP setting for the email client and your internet provider ,some limit the vehicle for sending over their network
Above should help ,get the correct settings from C Bell for use on their network

Mail will not send mail wirelessly: need to plug into ethernet port:

Hi:
This is weird. While my wife's ibook has a strong signal and can use Safari effortlessly, when she tries to send mail, Mail won't let her. In other words SMTP is the issue because she never has a problem receiving mail the POP server. Since we have several macs on a network, she has recently borrowed my CAT5 cable (removing it from the back of my B&W G3) and when the connection is made to her ibook, the mail is automatically sent. All the other computers have no difficuly receiving or sending mail from Sympatico. I don't think it's the ISP it's the program mail. I have not checked to see if Entourage (part of Office) has the same issue. All I've done was to trash the preferences file and removed the program and reinstalled. No Change. Any ideas? My wife is tired to using my ethernet cable

You’re welcome.
Both of our versions on Mail for our tiger systems is indeed 2.07.
If you’re running Mac OS X 10.4.8, it should be at least 2.1. Have you re-installed Mail? This is a common mistake. If you’ve reinstalled Mail from installation disks with an older version of Mac OS X, you must also reinstall the Combo Update for the type of computer and the version of Mac OS X you’re using, to bring Mail back in sync with the rest of the system:
About the Mac OS X 10.4.8 Combo Update
Mac OS X 10.4.8 Combo Update for PPC
Mac OS X 10.4.8 Combo Update for Intel
You may also want to read the following articles for guidelines on how to properly install system updates:
Troubleshooting installation and software updates
Installing software updates
Basically, you should verify/repair the startup disk before installing the update, no applications should be running while installing it, and you may experience unexpected results if you have third-party system software modifications (not normal applications) installed.

Mail will not send, Mail will not send

Why Can't I send email from my iPad? I previously was ably to do so. First lost the ability to send from one e account and today lost the ability to send mail from a second account.

If it was just one account, I would say to check the outgoing server settings, which you can still do, but the odds of them both going ahywire at the same time seem sort of slim. I t doesn hurt to check however.
Settings>Mail, Contacts, Calendars>Your email account>Account>Outgoing mail server - tap the server name next to SMTP and check in the primary server and make sure your username and password are entered and correct - even if it says that the password is optional.
You can try quitting the mail app completely and reboot the iPad as well. Sometimes that cures mysterious issues.
Go to the home screen first by tapping the home button. Double tap the home button and the recents tray will appear with all of your recent apps displayed at the bottom. Tap and hold down on any app icon until it begins to wiggle. Tap the minus sign in the upper left corner of the app that you want to close. Tap the home button or anywhere above the task bar.
Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.

Yeah stop trying to make Mac Mail work and just use Thunderbird. You really don't need 2 Mail programs.

Hi Nuch1,
I found an article that is contains very thorough Mail troubleshooting steps:
OS X Mail: Troubleshooting sending and receiving email messages
http://support.apple.com/kb/TS3276
You can use that article to figure out what part of the email "ecosystem" is the cause of the issue, and it can also help you attempt to resolve it.
Hope that helps,
David

TS3276 Mail will not send from any of my accounts & connection doctor indicates that I am connected

Mail will not send from any of my accounts & connection doctor indicates that I am connected

When did this start?
What specifically happens when you try to send Mail?
Are you able to receive mail from all of the accounts? any of the accounts?
Are all the email accounts with the same provider?
In Console > All messages search on Mail and see if there are any error messages

TS1307 cannot recognize mail password and will not send mail..iphone and web work mail no problem

mail will not send and continuously asks for password and rejects last documented password change. I cannot send mail only receive it on the MacBookPro BUT...I can get web mail and use send on iphone...mail cannot be recieved on iphone now.
help thankss

Use the Apple Mail Connection Doctor (Apple Mail's Window menu > Connection Doctor) as a first step.
Also recognize that Apple Mail tends to (also) toss out the same password error dialog for errors other than password errors. This means that network errors and network configuration can be reported as password errors. (And folks that receive the password errors can then reasonably try different passwords, which means that the wrong password can (also) then get recorded in Keychain.)

My iPad will not send messages from mail

Mail will not send outgoing messages. Error message says client does not recognise or has wrong password.

Your SMTP server is likely not set up or set up incorrectly. Check that all is set up correctly in Settings > Mail, Contacts, Calendars > [your account] > Account > Outgoing Mail Server > Primary Server

Mail will not send

Hi, I've had my iMac some time now but have only just set up the 'mail' option. I have definitely put in all of the correct details for all of my email accounts. I am able to receive email but it just will not send out any emails - from any of my 5 email accounts!
When I check the mail connection all is green (except for one of the outgoing servers for one particular email account). So why will it not send from the other outgoing server when it is green?! I use an iPhone and an iPad and my mail on those is fine (using exactly the same settings).
I have updated the software (as recommended by Apple for this particular problem) but it has made no difference. Every time I try to send it says 'Mail will not send with server...'
It's driving me crazy! Please help! Thanks.

This may not help, but a few months ago I was trying to send a message to members of my professional organization, but kept getting a similar message. I exchanged correspondence with Tech Help at my server to no avail. I thought the problem might have to do with the quantity of receoients, so I started deleting a few at a time from the list and resending. All of a sudden, it worked!
I finally narrowed it down to one address that had been preventing the message from going out. After I deleted and exactly retyped the address, I never had another problem. Never understood what had happened.

Updated my phone, now e-mail will not send because server does not allow relaying

Updated iphone 3GS to iOS 5, now my company e-mail will not send "because server does not allow relaying". I'm just an employee, not an IT type - have no idea what this means and I'm very frustrated. Also infuriated with Apple because THEIR update caused this to happen, yet I have to PAY for their support because I have an older iPhone. Someone please help.

razmee209, thanks for your reply. After signing up for the community, I saw that I wasn't the only one. However, I think I've solved it by looking over the comments in reply to others with this problem.
First, I think the iOS5 update may have made the phone default to IMAP setting. I noticed when I deleted my account and re-set it up that there is a large button at the top for either IMAP or POP. It is already defaulted to IMAP, but my account must be POP. So this is the first thing to check when you're setting up your account.
Second, I noted some other comments about needing to supply a username and password to the outgoing server even though it says optional. I included those, but got a message that it wasn't recognized (or something like that) and did I want to continue anyway. I told it to continue. After a few seconds, it verified my account, and now everything works.
Hope this helps others having this problem.

Mail will not send or receive. It intermittently stops working. Why?

Mail will not send or receive. It intermittently stops working. Why?

I had problems with sending emails from one server in particular, however, I would ask if you have gone to the page of your server and found specific instructions for configuring your mail. My iMAC would not send out emails, so I went to my (Italian) server's page and solved the problem.
It was not sufficient to let the MAC wizard connect you up with your server, and, indeed, MAIL invited me to consider installing the server's email manually. So doing, my problem was solved.
Your server's page should have a list of email programs (cf Outlook, Thunderbird, etc.) , with instructions as to how to configure them. Look for the item referring to Macintosh Mail, keep it in background in order to go back to it as you configure your mail.
My problem was that I could not convince Mail to accept the out connection, but when I eliminated my server entirely in Mail's Preferences, I added that server once again: Mail told me that it could not safely transfer my password and asked me if I wanted to set up the site manually. I clicked on manual, and found very precise specifications as to the number of the port to be used, then instructions on how to find the menu for the out mail, with a particular number I had to insert in the drop-down menu they specified.
It was not as complicated as it sounds here, but requires patience.

AOL mail will not send

AOL mail will not send from iPad. It goes to outbox and stays forever. Have deleted the account and re-added the account. It test fine and verifies with no problem, but every consequent send results in server error. Accounts work find on iPod touch and webmail. The issue is with mail app only. Any advice? I just configured four of these for the kids. The two that use hotmail have no problems...it's just the AOL accounts. I even added my AOL account...and it too, fails to send from iPad.

I have an AOL account and I do not have the AOL client loaded on my PC. Our ISP is Time Warner Road Runner. iPad is connected via Wifi to Linksys E3000 cable modem router, which is connected to Motorola SB5100 cable modem. iPad will receive AOL mail OK, but will not send. iPad will receive & send OK for Road Runner mail.
Here is how I solved the problem. Apparently Road Runner does not allow to be on their network and use other mail server such as AOL to send. My guess is that is their attempt to stop spam or phishing.
I added the secondary SMTP server, which is Road Runner's SMTP and turned both primary & secondary servers on so that I can use it when I'm not at home. It now works like a charm. Road Runner SMTP doesn't work with SSL, so I had to leave that off for smtp-server.xxx.rr.com, where xxx is the location such as san for San Diego. No User Name or Password necessary.
My guess is that this is the case or other ISP's as well. Hope this helps someone.
