Delete a Message Stuck in Outlook’s Outbox

Method 1:

Find the Message using Instant Search

Messages deleted using this method are permanently deleted and bypass the Deleted Items folder.

  • Close Outlook and wait a few minutes for it to close completely.
  • Type outbox in the Start menu’s search field.
  • Wait for Search to finish then find the message, select it and press Delete

Method 2:

Set Outlook to work offline using the File, Offline menu. Wait about 5 minutes or so before trying to delete the stuck message.

Save password setting not retained in Outlook or Outlook Express

When you connect to your Internet service provider (ISP) to retrieve messages from a Post Office Protocol 3 (POP3) server, your password is not retained even though you chose to save the password. Entering the correct password again does not resolve the issue.

The Safest workaround for this is to manually recreate a new profile and identity, but this article describes a shorter path to flush the password cache which is corrupted and might be the original cause of the issue.

Navigate to HKEY_CURRENT_USER\Software\Microsoft\Protected Storage System Provider

Take ownership of the key and subkeys.

Double-click the Protected Storage System Provider key to expand the key. Click the user subkey folder that is directly underneath the Protected Storage System Providerkey, click Delete on the Edit menu, and then click Yes in the warning message dialog box.
The user subkey folder resembles the following example:
S-1-5-21-124525095-708259637-1543119021-16701
Note For every identity that you have, there may be a subkey under theProtected Storage System Providerkey. To resolve this issue in all identities, you must delete all the user subkeys folders that are under theProtected Storage System Providerkey.  On the Registry menu, click Exit. Then, restart the computer.

We had a migration from Hosted Exchange to Office 365 and i was tasked with automating the local Outloook profile migration for Users:

I Created a GUI utility using powershell which would allow users to create an Office365 Profile and set it as default, I prepared PRF files for each version of office and an autodiscover.xml to be used for local autodiscover and uploaded them to a hosted site:
