Forum Discussion Good morning everyone, Over the past several months we've been experencing a very random issue where Outlook loses users credentials, and then when loading Outlook it prompts for the password, but goes away so quickly you don't have a chance to enter the password. Steps we have taken to resolve the issues. 1. We've cleared credential manager on the system 2. Repaired office (both quick and online). 3. Created new Outlook profiles (including deleting the .ost file). 4. Uninstalled/reinstalled Office completely.

Most times it works itself out after a few days, but I don't get why this issue continues to happen. Any helpful tips? thanks in advance dhendrix24 to Ash365 Aug 16, 2019 Ash365 I was able to resolve this issue by adding the following registry keys Credit to this article also https://superuser.com/questions/1349327/outlook-needs-password-but-dialog-box-disappears HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\Identity, create a DWORD value named EnableADAL and set it to zero.
