Outlook - Want both POP & IMAP account for same address

I have been using Outlook 2010 until it reached end of life recently. In it I was able to set up both a POP & IMAP account for the same email address. That way I could opt to not sign in to the POP account and read the messages via the IMAP account and leave them on the server for a while. Then some time later when I wanted the messages down on my PC I could sign into the POP account.

 

I just subscribed to Microsoft 365 and tried to set this same arrangement up in Outlook there and it won't let me do it. I've created a POP account and when I try to create the IMAP account it tells me "This email address has already been added". I suspect that what I am trying to do is no longer allowed/possible. Can anyone confirm this or, better yet, tell me how to accomplish what I want?

 

Thanks.

    Unfortunately, in the current version of Outlook (Microsoft 365), you cannot directly set up both POP and IMAP accounts for the same email address within the same profile, you may create different Outlook profile to handle

      Correct, that changed several years ago with the introduction of Outlook 2013. 

       

      I have found one way to trick it, but only if you have two aliases on the account. Add the account then change the From address to the second alias. Add the account again.

       

      I have not tried changing the From address on the first account back to the original - I did it to add an iCloud+ custom alias to Outlook along with my iCloud address. 

       

      The steps I used are in this article:

    BarryEBit is still possible to setup pop3 and imap with the same email address in outlook 2019/365.

     

    1st step is to disable the account wizard creator so you will get the good old configuration way, to do this just insert in the registry the following

    [HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook\Setup]
    "DisableOffice365SimplifiedAccountCreation"=dword:00000001

    keep in mind that in this way you disable all new authentication modes depending on your email provider (try it to configure accounts in a different windows local user profile, so you get clearly what i mean) 

     

    2nd step, depending on your email provider, you have to create a dedicated app password (as an example, gmail requires two factor authentication enabled, before you can configure password for old apps) 

     

    3rd step, using the app password created in the second step, you can configure your account in the old classic way like in the old outlook versions  

     

    i expect this way works untill your mail provider keep active POP3/IMAP mode to downloard or sync

    BarryEB new versions of outlook no longer allow an address added twice. If you have an alias on the account and can use it to log in, you would be able to use that address to sign in - but not when you use the one address. 

     

    My suggestion: 2 profiles, with the POP pst file in both profiles. Switch to the POP profile when you need to download. 

     

    Or: keep the pst in the profile and move the mail from IMAP to pst when you are ready to remove it from the server.

      Diane_Poremsky_MVPI'd basically like to have the same ability as the original poster described in Dec 2020.

       

      The only differences are that I'm asking 2 years later and

      1) Microsoft has finally ended support for WIN7 on my "daily driver" pc

      2) I've updated my previous OUTLOOK 2016 so that it's now the OUTLOOK that's buried as a piece of my MICROSOFT 365 subscription

      3) and finally I see that as of late November/2022 I see that MICROSOFT has also just "Deprecated" the use of "basic authentication" in POP accounts (it's not good enough for current security standards) https://learn.microsoft.com/en-us/exchange/clients-and-mobile-in-exchange-online/deprecation-of-basic-authentication-exchange-online 

      • and I'm guessing that's what's now causing the symptom I'm seeing. My POP account with my internet service provider has worked flawlessly for many many years, but now it's unusable.
      • it still RECEIVES all new emails normally ... but it no longer lets me SEND any new emails + but additionally it wont even let me OPEN and READ any emails sitting in my INBOX (i.e. in my existing OUTLOOK.PST file).

      I've accepted the fact that I need to switch to an IMAP connection to my internet service provider whether I like it or not, but this is my question.

       

      Because I have years of email "history" sitting in my OUTLOOK.PST file that I want to keep accessible ... and recognizing I can only use it to OPEN and READ old emails, but can't use it to SEND any emails ... would you have any suggestions on how I could do this with my existing single email id with my internet service provider?

       

      Thanks in advance for any suggestions you might have for my convoluted question :flushed:.
