Corruption can occur if you transfer a .pst file from one computer to another. This is what I did which caused this error message when trying to send/receive email.
Here is a solution that can fix the problem:
1) Click …
Category: Microsoft Outlook
Microsoft Outlook – Click a link restriction
If you get this error when clicking a link in Outlook…
“This operation has been cancelled due to restrictions in effect on this computer. Please contact your system administrator”
…try this fix from Microsoft:
Microsoft Outlook – How to unblock a file extension that Microsoft Outlook (Office 2007) won’t allow to be read or sent
You can define what outlook blocks or does not block by using this registry key
[HKEY_CURRENT_USERSoftwareMicrosoftOffice12.0OutlookSecurity]
“Level1Remove”=”.mdb;.zip;.exe;.url;.reg;.app”
Add to “Level1Remove” all extensions you do not want Outlook to block.
