Outlook cannot open Calendar, it may be damaged

Upon opening Microsoft Outlook 2007, I was receiving the message "Outlook cannot open
Calendar, it may be damaged".  I did some searching and found a quite easy fix.


OS: Windows 7 Pro
Software: Office 2007


Solution:  
First off, if you have outlook open, close it.  Next, navigate to one of the following locations, looking for Scanpst.exe:

• disk drive:\Program Files\Microsoft Office\OFFICE12
• disk drive:\Program Files\Common Files\System\Mapi\1033\
• disk drive:\Program Files\Common Files\System\Mapi\1033\NT
• disk drive:\Program Files\Common Files\System\MSMAPI\1033
• disk drive:\Program Files(x86)\Microsoft Office\Office12
• disk drive:\Program Files(x86)\Common Files\System\Mapi\1033\
• disk drive:\Program Files(x86)\Common Files\System\MSMAPI\1033

Once you have found scanpst.exe, double click the exe.  Click browse and navigate to your pst file.


Default PST Locations:

• Windows 98 or Windows Me: disk drive\Windows\ Local Settings\Application Data
• Windows NT 4.0: disk drive\WINNT\Profiles\username\Local Settings\Application Data
• Windows XP or Windows Server 2003: disk drive:\Documents and Settings\username\Local Settings\Application Data\Microsoft\Outlook
• Windows Vista: disk disk drive:\users\username\AppData\Local\Microsoft\Outlook

 Click start and let the tool run.  If it finds any errors, click repair.  Open outlook and the calendar now can be opened.

This operation has been cancelled due to restrictions in effect on this computer

This was an issue with Microsoft Outlook when clicking a link in an email.  It would give you the message "This operation has been cancelled due to restrictions in effect on this computer.  Please contact your administrator."  This is caused by Outlook being confused to which browser to use.  A lot of threads I read blaming Chrome when a user would uninstall it.  I was unsuccessful fixing this error with installing and uninstalling Chrome.  But I was able to fix it using Firefox.

OS: Windows 7 Professional
Problem: Outlook 2007
Solution:  I opened firefox and made it the default browser.  I closed outlook and reopened it.  I tried clicking a link in an email and it launched firefox.  Success!  Now getting it to launch in IE (since this is what the person wanted).  I opened IE and made it the default browser, closed outlook, reopened outlook and tested again.  The link successfully opened in IE.
