Outlook Crashes on Startup / mso.dll

Problem: Outlook crashes on startup, or after clicking the File menu, or anytime shortly after launch. Viewing error details in event viewer or reliability history indicates that mso.dll is involved.

Resolution: Go to Account Settings. Remove any listed Internet Calendars under the Data Files tab and the Internet Calendars tab. Alternatively, this can be accessed through Control Panel>Mail>Email Accounts.
