If you have an issue with attachments in outlook (any version) basically when the attachment includes consecutive dots (…) or exclamation mark (!) the files are blocked and you receive an error message: “Opening mail attachment. You should only open attachments from a trustworthy source”
If you have problems with a custom form that you have created for outlook and see one of these messages:
“To help prevent malicious code from running, one or more objects in this form were not loaded.” or the vbscript doesn’t run.
The fixes have been releases from Microsoft last Friday July 28. Go to this website and find the correct KB according to your office version.
