I have an iphone 4. I used to be able to delete an email without it being deleted from my comcast email and viceversa. Now when I delete on my desktop it deletes on phone, when I delete on phone it deletes on desktop. There are a number of emails I want to save but I don't need them on my phone. Why can't that still be done? Do I have to download all to outlook now?
What you are describing is normal if the account is enabled both on the pc in a client and on the phone and both use IMAP. You probably had one or the other using POP3 before. With IMAP, if you want to store a local copy on the computer, you would need to put it in a folder that is not affected by IMAP. I use Mac Mail on my desktop, and it has a section called "On My Mac". Those folders have emails in them only on my machine. I assume Outlook has something similar, although I've never used it.
