Office365: Strip specific email addresses in "To:" field with transport rules

I've setup a transport rule to redirect all messages from [email protected] to [email protected].

The redirection is working fine, but the support system identifies [email protected] as a participant because it matches the To: field in the original mail header and that will trigger a notification to the same [email protected] address to confirm that a support ticket has been opened.

So the confirmation mail then will be redirected back to the support system and we have a loop.

For now I was only able to completely remove the To: field in Office365, but that will also remove legitimate extras addresses that would be interested on the issue.

The transport rule was basic:

Apply this rule if Is sent to '[email protected]' or '[email protected]'
Do the following:
* Set audit severity level to 'Do not audit' and 
* Remove this header: 'To' and
* Redirect the message to '[email protected]' and 
* Stop processing more rules

My question: Is there a more elaborate way to create custom transport rules in Office365 to match the original address and remove only those who matches the rule?

Just guessing: You could try to delete the remove "To" action, and then add an "Except if" condition. Let notification emails not be redirected and exclude notification emails that will cause loops.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
