changing color of category in own mailbox is visible in other mailbox

Question

changing color of category in own mailbox is visible in other mailbox

Kurt Stichelmans 661

situation:
Exchange 2016, Outlook 2016.

User A has his own mailbox in Outlook.
He also has another mailbox X (full access + sendas permisions). So configured as a shared mailbox setup.

User B has configured Outlook with mailbox X as his primary mailbox.

When user A changes the color of a category in his outlook, user B sees that color change in his Outlook.

How is that possible?

Any explanation that can clarify this behaviour?

Thanks
Kurt

Hi @Kurt Stichelmans ,

Welcome to our forum!

According your description, I noticed that User A has changed the color of a category in shared mailbox, right?

If so, based on my test and considering the nature of the shared mailbox, it is expected that the same change will occur in the shared mailbox of User B. It's by design.

If you don't want the contents of the shared mailbox to be changed, you can remove the Send As permission for User A. For more information about shared mailbox, please refer to: Shared mailboxes in Exchange Server.

Well, user A changes a color of his own mailbox. And he has in Outlook also the permissions to see another mailbox (mailbox X) with full access and sendas permissions).
So when he (user a) changes a color of a category in his own Outlook and with his own mailbox as primary) the user B who has the mailbox of user X as primary mailbox sees that color change.

to be correct: mailbox X is a full mailbox with an account. But that account is not used to logon into a server (e.g. citrix).
User B who has the mailbox X does use that account of user X to see the content of the mailbox X but he logs on with his own credentials on the citrix server.

So I guess that keeps it: by design ???

Hi @Kurt Stichelmans ,

Thanks for your reply!

How did you change the color and what message color did you change?
And do you mean that User A has configured both his own account and shared mailbox in his Outlook?

If so, it's suggested that you could configure his own account in another profile(Control Panel>Mail>Show Profiles>add) or on web mail, and then try to change the color to check if there're any changes in shared mailbox.

Next week the client has time. At that time I will have a look at what he really does because I reproduced it but for me it is working fine.
There is no interference with another mailbox if I changed the categories of myself (my mailbox).
