Gmail-Outlook mail delete problem

I am using Outlook 2007 to download mails using POP3 from Gmail to multiple PC in the network.I am unable to automatically delete mails from Gmail with the setting 'Remove from server after 100 days' in Outlook account settings.It was deleting properly sometime back.Please help me to solve this problem of mails not getting deleted.

Thank you:)

I'm not sure but I think you need to set "When messages are accessed with POP" (under Settings/Forwarding Pop and IMAP) to "Delete Gmail's copy" and then save the changed in your gmail account. Also, try using IMAP instead of pop and see if that makes a difference.

I tried using 'Delete Gmail's Copy' option,but the mail gets deleted as soon as it is downloaded from outlook.But i want it to stay in the Gmail server for 100 days ..and prefer using POP3.

I would use the archive feature in Outlook and set it clean out messages after 100 days! I also, read on other sites that it is better to use IMAP for use with multiple accounts on gmail.
