    Outlook 2013 Asks for Password to open OUTLOOK.PST


    I have a Dell Inspiron 660 running Window 8.1 Pro.

    I had been using Outlook 2013 for about a month with no problems, when I got a message saying my OUTLOOK.PST file was approaching maximum size of 2Gb. However, I could not open it to compact it or delete items to bring the size down. I just kept getting the "approaching maximum size" error.

    Outlook was NOT asking for a password for my mail server, It's specifically asking for a PW to open OUTLOOK.PST.

    So, I opened the OUTLOOK.PST file in Outlook 2007 successfully, did some housekeeping, and reduced the size to about 700Mb. However, when I tried to open the PST in Outlook 2013 again, I was prompted for a password to open the PST. I tried my MS Account PW, and several other PWs, but none worked. I never set a PW for the OUTLOOK.PST in the first place. I was never prompted for a PW before the "max size" error came up.

    I am able to open the file in Outlook 2007 without being prompted for a PW but every time I try to open it in OL2013, I get the PW prompt.

    I have also run the SCANPST.EXE utility on the OUTLOOK.PST file, but that has not changed the PW prompt.

    Any suggestions would be appreciated.

    According to this page you shouldn't have reached the limit of the .pst file size:

    Outlook 2013 Password


    Thanks to everyone for the responses to my query.

    Not sure why I got the size limit error for OUTLOOK.PST, but I definitely got it when the file was slightly less than 2Gb. Could it be that the file was created when I was still running OL2007?

    Also, I tried Paul Hogan's suggestions but I still get prompted for a password.

    Still hoping that someone else has something for me to try to correct this problem.

    TIA

    I have no idea what is going on, but it seems to me that Outlook is asking for your User Account password.
    I'm not an Outlook user, but email agents should respect the login account, in general.

    Outlook Password Problem


    I've tried using my Windows login (Microsoft Account) PW, the PW for the email account, and any other PWs I could think of, but none of them worked.
