Office 365 rule to only allow a parent to email a single member of staff?

[MrWu]

Strange one

 

Is there a rule I can apply in Office 365 to allow a single parent to be able to only email one member of staff in our school ?

 

ie : [email protected] > [email protected] ok

 

[email protected] will reject [email protected]

 

thanks!

Does it have to be reject? For that kind of situation we make it redirect all the messages for that user , so parent thinks it sends, teacher doesn’t get spam, and then whoever you want to see it has it etc

Is this a single contact in school for all external inquiries, a parent getting a "designated" staff member, or simply emailing any staff member but only one at a time?

A transport rule with something like "If sender is [email protected], redirect to staffmember@school"

 

..assuming the parent doesn't have N+1 email addresses/doesn't change their email address.

I do that too.

Thanks all

 

Would this work?

 

If the message...

Includes these words in the sender's address: '[email protected]'

Do the following...

Redirect the message to '[email protected]'

Rule comments

 

Rule mode

Enforce

Additional properties

Sender address matches: Header

Version: 14.0.0.0

 

Only issue is does the 'include these words in sender's address' explicitly that match? Not a wild card?

 

That's the best and closest options I can select from my Rules administration options..

Do you get an option to match the address in the FROM header?

 

I have fixed my screenshot above.

You can do it two ways.

 

Option 1:

Two rules:

 

If sender address = parent

and destination address = particular person at school

then

Stop processing more rules

 

Then have a 2nd lower priority rule

 

If sender address = parent

Then reject/quarantine the message

 

Option2:

 

If sender address = parent

Then reject/quarantine the message

Except if: The destination recipient is particular person at school

 

 

 

 

Ideally you should redirect or quarantine the message rather than blocking, for obvious reasons..

This should work. However you can also choose "if the sender is..." and then type the external address in and press check names when selecting the sender address. This will work even if it is external. You don't have to resort to the list-type option. You should also probably add an action to generate an incident report when this rule triggers so that you are aware, depending on the circumstances.
