Manually add shared mailboxes in Outlook on PC
This is a guide on how to manually add a shared mailbox to Outlook if it does not show up automatically, which might be common when all mailboxes are migrated to Office 365 while your own mailbox is not migrated or if does not automatically shows up.
Start by in Outlook clicking “File”.
Then select “Account Settings” and when the dropdown menu drops down select “Account Settings…”.
Select your KI email and click on the button “Change…”.
Then click on the button “More Settings …”.
Click on the tab “Advanced” and then the “Add…” button.
Enter the email address for the shared mailbox you have access to and then press “OK”.
Continue by pressing “OK” on the window behind and then press “Next >” and then “Finish”.
Now it is done, and you should see the shared mailbox below your own mailbox folder structure.
You might need to expand the mailbox to see the folders. You can do that by clicking the small arrow to the right of the name of the shared mailbox.
