Is your phone email set to POP or IMAP?

Server type is POP and server name is: mail.twc.com if that makes a difference. That's what tech support for TWC had me change it to for incoming and out going server name.

Hold on just realized you asked about my phone not PC

My phone looks to be IMAP if I looked in correct place.

With IMAP the messages are left on the server and you view them remotely from your devices. If you delete the message from your phone it will remove it from the server and it will not be available for the PC to download.

IMAP is the best choice when using multiple devices as long as you understand how it works.

With POP the messages are downloaded from the server to your device and removed from the server unless you set the device to leave the message on the server. The drawback is you will have to manage messages on each device and the server separately. POP only knows about the inbox so messages sent from your phone will not be visible from the PC or vice versa.

IMAP syncs all folders since you are only viewing folders on the server.

So if I understand what you are saying if I delete the messages from my phone prior to looking at them on my PC then it would appear as if i did not receive them on my PC. However if i read them and do not delete them from phone they are still on my PC. If I change my phone to POP this would stop, correct? Is it worth changing phone or should I just deal with it. I do not use email for work, just personal stuff.

First step is Google IMAP vs pop so you know how each one works.

If you change the phone to POP then you need to set the option on the phone to leave the messages on the server. Like I stated the default POP operation is to download messages and remove them from the server.

As for your original statement. With your phone being IMAP, you are just viewing what is on the server. If you delete from the phone before the PC has downloaded the messages they are gone from the server and when the PC connects to the server there is nothing there.

Thanks for all the help, now I know why my email was missing. I will look into POP vs IMAP at a later date when I have more time. For now I will not delete messages from my phone. Thanks again!!

That is probably the best approach, using pop on your phone will mean you will not get the read status updated on your desktop. This might not be important to you, but having to go through a list of mail going seen, seen seen becomes tiresome very quickly. As IMAP synchronizes folders as well as individual emails, simple deleting on your phone should see those mails appear in the deleted/trash folder unless your phone is emptying it's trash in a short period of time. As phone storage is limited, check what it is doing with these mails and things like emptying the trash.

Same issue with Spectrum Time Warner. TB contacts the server, may or may not say it is downloading emails - NOTHING comes in! Phone and Kindle both receive emails - two different accounts - no problem - all set to the same POP settings! Get email command does not even work most of the time. In the past I would delete some junk mail from the STW server and that would fix it. After doing this you have to reboot the computer for TB to work. It was only one account or the other, now it is BOTH accounts at the same time! Now deleting emails is not fixing this. I thought it might be filters deleting from the POP server so I deleted all of them - DID NOT WORK.

IT IS NOT NORTON AV AND NONE OF THESE SOLUTIONS WORK:

It would be better if you started your own thread. All the people in this one do not want to get emails about a different problem.

Do you have your devices set to leave messages on the server?

Seemed like the same unsolved issue to me but I will post a new topic. All devices are set to leave emails on the server. The server deletes them after 30 days.

Well, I thought I would start a new thread but after 4 -1/2 hours on this forum with no help in sight and 15 minutes just to figure out how to re-register and another 20 minutes trying to find out how to post a problem with no luck, I think I will just call it a day!

Interesting, why are you trying to re-register?

As for asking your own question. It is a bit of a pain, but not that bad. We just make you step through a process that displays knowledge base articles first.
