Security Level
Set the security level to one of
| Very high | only run macros from trusted file locations. |
| High | only run signed macros from trusted file locations. |
| Medium | requires confirmation before running a macro from an untrusted source |
| Low | run all macros without confirmation |
If the security level is very high or high and a macro is not located in a trusted file location, trying to execute a macro results in the following warning:
For security reasons, you cannot run this macro.
