**Why the Problem Happens
-
To solve this problem, it is helpful to know what tends to go wrong. The main causes include:

### **Server-side issues

Sometimes the glitch isn’t with your phone at all—the glitch is on the Comcast/Xfinity email server side. If that server is down, or there is some issue with it, your iPhone’s Mail app won’t connect properly. 

Issues with the connection or device

If your iPhone is on WiFi that isn't really connected to the internet, or if a VPN or firewall is interfering, email may fail. One user reported email downloaded only when WiFi was off. 

Incorrect Settings in account

Mail.app requires the proper incoming/outgoing server settings (IMAP & SMTP) in order to work correctly with Comcast. Incorrect ports or host names can block things. 

***Security & access to third parties***

Comcast has a setting called **Allow Third-Party Access Security** which sometimes needs to be enabled, if an app such as Apple Mail is trying to access your account. If it’s off, you’ll have problems. 

Software bugs or device corruption

An older iOS version or corrupted settings in your iPhone can also mess up email functionability. Most fixes suggest updating iOS or restoring settings.

How to Confirm the Issue
-
Run these quick checks before moving into the deeper fixes:
* Are you able to access your Comcast email using the web browser-based interface on either your phone or computer? If so, then the server and credentials should be okay.
* Is your iPhone connected to the internet (either WiFi with actual internet or cellular data)? Try loading a website in Safari.
* Are you using a VPN? Try turning it off and see if you have access to email.

* Does your issue happen over WiFi but not on cellular (or vice-versa)? That could be an indicator of a network or router problem.

* Did this issue start immediately after changing a password or updating iOS? This could indicate that the device settings need to be updated.

## **Fix 1: Check Network & Connection
Go back to basics: if your iPhone cannot access the network, your mail application cannot connect. Try these steps:
* Go to **Settings → WiFi**, turn WiFi off and then on, and try sending email using cellular data.
* If you’re on WiFi and email fails but cellular works, restart the WiFi router (unplug it for 30 s, then plug it in).

* Ensure that airplane mode is off.

* Temporarily disable any VPN and/or proxy you are using, and test again---some users found VPNs blocked Comcast email.

Open Safari on the iPhone and go onto any website to verify internet access, such as google.com.

If the internet is working fine and the Mail app still isn't working, proceed with the next fix.

## **Fix 2: Check Email Account Settings
One of the most common causes is incorrect incoming/outgoing server settings. Here are the correct details for Comcast email on iPhone:
IMAP Incoming Mail Server
* Hostname: `imap.comcast.net` 

* Port: 993

* SSL: ON
* Authentication: Password
* Username : Your full Comcast email address
SMTP OUTGOING MAIL SERVER (SMTP)

* Hostname: `smtp.comcast.net` 

* Port: 587
* SSL: ON
* Authentication: Password

* Username: Your full Comcast email address

How to check on iPhone

1. Go to **Settings → Mail → Accounts → [Your Comcast Account] → Account → Advanced**

2. Make sure the above settings have been entered correctly.

3. If anything is wrong, correct it and save.
4. Then go back and test sending and receiving.

If the settings were wrong and you fixed them, test again. If it still doesn’t work, continue to Fix 3.


## **Fix 3: Remove & Re-Add the Account

Sometimes the easiest route is to remove the email account from your iPhone and setup it anew:

1. On the iPhone, go to **Settings → Mail → Accounts → [Your Comcast Account] → Delete Account.

2. Restart your iPhone.

3. Restart and then go to **Settings → Mail → Accounts → Add Account → Other → Add Mail Account**.

* Enter your name, Comcast email, password and a description.
Then enter the IMAP/SMTP server settings as described in Fix 2.
4. After adding them, open the Mail app and test sending/receiving.

According to many users, this method worked when no other fix did.

## **Solution 4: Allow Third-Party Access

If it worked previously and stopped working without any changes on your end, this is a good possibility: Comcast has toggled off the “Allow Third-Party Access” security setting.

Here's how to enable it:
1. Sign into your Comcast/Xfinity email from either a computer or browser.
2. In the mail interface, click on the gear icon and select Settings → Email Settings → Security.

3. Look for **“Allow third-party apps”** or similar and make sure the box is checked. ([Xfinity Community Forum][2])

4. Log out, head back to your iPhone, and check the Mail app again.

If the setting was off and you turned it on, test email functionality again.

## **Solution 5: Update iOS & Restart Device

Email apps can break due to software bugs or incompatibilities. Make sure that your iPhone’s system is updated:
* Go to **Settings → General → Software Update **.
* If an update is available, install it.
* Restart your iPhone after updating.

* Then test your Comcast email in the Mail app.

Updating often resolves obscure compatibility issues and bugs—and many users found email started working again after doing this.

## **Fix 6: Reset All Settings (As a Last Resort)**

If all else fails, resetting all the settings on your iPhone will clear hidden system issues without touching your data: photos, apps, or whatever.
Here's how:
* Go to **Settings → General → Transfer or Reset iPhone → Reset → Reset All Settings.
* Enter your passcode and confirm.
* Your iPhone will restart.

* You may need to re-enter WiFi passwords and preferences after restarting, but then try adding your Comcast email again; see the steps below under Fix 3.

* Test Mail.

Because this is more disruptive, use it only after the previous methods fail.

## **Preventive Tips: Avoid Future Issues

Here are practical tips to keep Comcast email running smoothly on your iPhone:

* Regularly update iOS and applications.

* After updating your Comcast/Xfinity password, renew the password in the Mail app without fail.

* Enable **Push** or appropriate Fetch settings: **Settings → Mail → Accounts → Fetch New Data**. 

Avoid using aggressive VPNs or firewalls that could block e-mail server ports.

* Periodically check the “Allow third-party access” setting in your Comcast email security settings.

* If switching networks, make sure your Mail app has internet access on both.

**Frequently Asked Questions**
**Q1: Why did my Comcast email suddenly stop working on my iPhone?
A: It is possible due to a changed password, an iOS update, a toggled email security setting, or network issues. 

**Q2: My password is correct, but I still get “No password provided” error. What can I do? 
A: Try removing the account from your iPhone and re-adding it (see Fix 3). Also confirm the third-party access setting is enabled in Comcast.  

**Q3: If Mail app fails, can I continue using Comcast email on the web? Q: Can you log into xfinity.com or login.xfinity.com via browser to get access to email? A: Yes—you can, but that workaround is less convenient.

Q4: I use Comcast email on my iPhone. Should I use IMAP or POP? A: Use IMAP. It syncs. POP is older and not suggested for these modern multi-device worlds. Many guides mention to use POP only if it cannot be helped. 

Q5: My e-mail stopped working only when connected to a certain WiFi network. Why? 
A: The router or ISP of that network may be blocking the necessary ports required for Comcast email (IMAP/SMTP). Please try cellular or a different WiFi. At least one user discovered that turning off WiFi allowed email to work.

Q6: Since I upgraded to iOS 18, my Comcast email no longer works. Is this a bug? A: Yes, some users reported the issue arose after iOS 18 update. Make sure you update to the latest patch and then re-add the account.
