On accepting a shared folder the user receives the message that he already has it

When the user wants to receive a shared folder, he receives the following message:
"You have already installed this shared folder".

The shared folder is the Mailbox of another user. And the receiving user has already accepted a similar folder from another user.

This is working as designed.

Steps to duplicate:

1. create 3 users: USER1, USER2 and USER3
2. login to GroupWise as USER1 and share your mailbox to USER3. Logout as USER1.
3. login to GroupWise as USER2 and share your mailbox to USER3. Logout as USER2.
4. login to GroupWise as USER3. Accept the shared folder from USER1. There will be no problems.
5. login to GroupWise as USER3. Accept the shared folder from USER2. When opening the mail, you will receive a pop-up with the title "Install shared folder" with the following content: "You have already installed this shared folder".

Normally when accepting a shared folder, you will have a window where you can select the folder to be placed and also with an option to change the name if needed. This is missing in this case you want to accept a second shared folder from type"mailbox".
