Our Organization has 2 email accounts for everyone.
user@companyA.com and user@companyB.com
All mail sent to user@companyB.com is forwarded to user@companyA.com, no mail is left in the Inbox of user@companyb.com
When they Turn on Out Of Office for user@companyA.com they also setup a Rule that says any message Addresses Specifically to user@companyA.com, deliver the email to insidesales@companyA.com.
Sending an email to user@companyA.com then gets forwarded to insidesales@companyA.com.
sending an email to user@companyB.com does not get sent to insidesales@companyA.com
If we setup the Out Of Office for user@companyb.com Account and they also setup a Rule that says any message Addresses Specifically to user@companyB.com, deliver the email to insidesales@companyA.com.
sending an email to user@companyB.com does not get sent to insidesales@companyA.com.
Looking at the Message Tracking I can't see the forwarding rule getting fired for the user@companyB.com OOF.
This happens for a group of people. When I do it on my own, it works fine.
