One of our customers contacted us with an Outlook problem.
They said after they added an IMAP account to Outlook, the application crashes permanently.The eventlog showed the following error: (thats a German OS)

We started outlook.exe /safe, but it still crashed.
After we removed the new added IMAP account through “Control Panel -> Mail”, Outlook worked without any trouble.

We figured out that KB2956128 must include an error because that update installed a new version of “pstprx32.dll”.

After we uninstalled this update and added the IMAP account again, everything works like a charm again.
