Outlook 2013 crashes on startup every time after calendar publishing to WebDAV. Safe Mode does also not work. Profile corrupt after calendar publishing

I published my calendar to a WebDAV folder from Outlook 2013. After restarting Outlook, it crashes at Startup every time. Tried Outlook /safe, but that did also not work.
Found out, that somehow my Outlook Profile seemed to be corrupt.

How-I-fixed-it:
I saved away my .pst-folder. (To be on the safe side)
Then I created a new E-Mail Profile and was able to start Outlook again without problems. Calendar, Tasks and Contacts were restored from my Outlook.com account. I still try to figure out, why this happens. There are other threads on the net that report similar Problems with calendar issues causing Outlook to Crash.

Outlook calendar publish to WebDav server login failed - How to change cached credentials in Windows 8

Recently I changed the password of my WebDav-Account. After that, Outlook stopped to publish my calendar to the Server. I tried to re-publish the calendar, but Outlook did not prompt me for the username / Password and still told me "Login failed".

How-I-fixed-it:
I went to system control -> user accounts -> credential manager -> windows logon credentials
There i found the setting "MSOutlookGeneric - MyWebDavServer". Open the tab and use "edit" to Change the credentials or delete the entry to let Outook prompt you for the login credentials again.

In German / Deutsch:
In der Systemsteuerung findet sich unter Benutzerkonten -> Anmeldeinformationsverwaltung -> Windows-Anmeldeinformationen "MSOutlookGeneric - MeinWebDavServer". Den Tab ausklappen unter unter "Bearbeiten" das Passwort eingeben.
