Installed Outlook 2013 update on November 25, 2013 and since then I keep getting a pop up title Windows Security, Microsoft Outlook, Connecting to email. It displays my login and password and there is a check box to remember credentials and below that a box to Use another account.  

I can retype my password, click on Remember my credentials, click OK and the same window pops up about three or four times in a row then goes away for anywhere between 15 minutes to an hour.

Went to Control Panel > Credentitals and deleted everything

Went into account settings and checked everything there and nothing has changed.

If I click OK or CANCEL there seems to be no difference.

Running Windows 7 Ultimate, Office 2013 (standalone) with Exchange through provider.

How can i get this resolved asap?

Hi wwhite,

Thank you for your question.

I agree with Eds suggestion.

You could contact Exchange provider to make sure the same authentication way on Both Exchange server sider and client silent.

We could check authentication on client by the following steps:

1.        Navigate to Control panel;
2.        Click Mail and choose email account;
3.        Click your profile and click change->More setting->Connection->Exchange Proxy Setting;
4.        Then we could check Proxy authentication settings;
5.        We could also check Security->Logon network security.

If there are any questions regarding this issue, please be free to let me know.

Best Regard,

Jim
