There exists a flow process that can do what you want.
Google for "autoreply flow".
There exists a free app for Office 365 named "Custom signatures" from IdeaSynthesis LLC.
We have just updated BCCtoGroup tool. Now it auto-populates the From: field when you reply.
the tool named BCCtoGroup can solve the part of the problem.
Unfortunately only on Outlook 2016 and only if you have changed the From: feild.
Anyway it will be one manual step instead of 2 ones.
"As an Admin, I want the ability to force all external mail sent in reply to these group messages to be sent to the external user, either 'As' or 'On Behalf of' the Group, thus ensuring all subsequent communication comes right back into the Group."
the problem is how to detect an "external mail sent in reply to these group messages".
Let's suppose an external user sent a message1 to you directly and message2 to the group, You have replied both. How the software can understand that "RE: message2" is sent in reply to a group message? Searching in all groups is not an option.
What do you think about that?
Please explain me what do you mean exactly?
You _can_ manage SMTP proxy addresses using Set-UnifiedGroup commandlet.
You can now use a dot in the email alias. We are working on providing the ability to edit the email address of a group after creation.
For the ability to edit the email addresses, we now have the following roadmap item: https://products.office.com/en-US/business/office-365-roadmap?filters=&freeformsearch=27891&featureid=27891
Brad, you wrote:
"If I do remember to change the from line I must also CC the group, or again, the message will be in my sent items folder bypassing the group".
There exists an add-in for Outlook 2016 that automates this process. Every e-mail sent as or on behalf of Office 365 group is BCCed to that group and become visible for all members. Google for BCCtoGroup.
There exists a cloud service that implements the sender address rewriting.
Just google for "address rewriting in Office 365".
Google for ChooseFrom 365 cloud service.
This feature is available for ChooseFrom 365 users now.Victor Ivanidze supported this idea ·
Have a look at this tool:
As a workaround you can use a third-party cloud service that provides the address rewriting functionality.
