I was thinking about doing a contest or something special involving prizes to celebrate my 1000th post, but I only got as far as the thinking part… it's hard to believe I've been doing this 9 years now (as of July 14). Yes, I can do the math: 9 years x 52 weeks x 3 tips per week is a lot more than 1000 but I took some weeks off and was a slacker the rest of the time.
Now back to our regularly scheduled tip…
Today's tip is for users with accounts on Exchange server.
It's difficult to use rules on email sent by co-workers. You can make individual rules by selecting a name from the GAL, but when you try to create a rule that applies to everyone within your organization, you discover it doesn't work. This is because Exchange doesn't use SMTP addresses for internal email, it uses x.500 addresses, which look something like this:
/o=organization/ou=Exchange Administrative Group (FYDIBOHF23SPDLT)/cn=Recipients/cn=alias
Like SMTP addresses, you can use a snippet of the x.500 string in a rule.
When you are creating the rule, enter /o or another unique part of your Exchange address as the condition in the With words in the sender's address. In highly organized corporations, where each business group has their own organizational unit, you can limit the rule to just users within a group, by using /ou=group-name
You can use this same technique in the filter dialog used by custom views, search folders, and automatic formatting.
