Outlook 2007
since 3 days Outlook refused to have contact to my Incoming mail server (POP)
Yahoo and Outgoing mail server (SMTP)

Since 3 days wihtout any settings changing, outlook 2007 is refusing to sent and received any mails from my two accounts.

With my other two accounts by the same Mail Provider Outlook is sending and receiving as usally-

The other both accounts in Outlook 2007 is always asking for the Network Password.

The window mask for entering the Network Password pop up several times during my work like writing or looking on the screen.

I had meanwhile deleted several times my two accounts from Outlook 2007 and created the same two accounts with the same pasword as many years ago and Outlook were runing brilliant.

With some information I went into the registery to look for the Outlook file and I have find both accounts there.

I had delete these two too and started againg to create on the Outlook 2007 platfrom again my former both accounts.

The other both by checking to get coneced to my Mail Provider works perfect.

I Used Windos 10 with the news updates and with the Mail Programm from windows 10 it is possible to sendt and received with both accounts myn test mail.

Although I do not have any problem to receive any mails to my accounts from my Email Provider Yahoo or my Android Smart Phone.

With kindly Regards

Yours sincerely

    Hi @Dirk Baumbach ,

    Welcome to our forum.

    Please kindly understand that Office 2007 has actually reached the end of its support lifecycle, meaning there are no new security updates, non-security updates, free or paid assisted support options, or online technical content updates, it's recommended to upgrade to the later version of Outlook to get a better user experience.

    Accoring to your description, the issue may be more related to your outlook client, due to the end of support, I couldn't test on the same environment with yours, as I know, the corrupted send/receive file or outlook data file may cause any send/recieve issue, have you tried to test on a new Outlook profile? If not, it's suggested to create a new Outlook profile and readd your accounts to check if the issue has any difference(Control Panel>Mail>Show Profiles>Add>readd your account)

    If the issue still exists, it may caused by your corrupted outlook, please try to repair your Outlook client to check.

    Hope your issue would be resolved soon.
