One of the very popular features of Exchange Online in Office 365 is the ability to create Shared Mailboxes. In Exchange Online you are free to create as many Shared Mailboxes you like. A Shared Mailbox smaller than 5GB in size do not require a license.
Many customers will want to have one or more shared mailboxes for e.g. firstname.lastname@example.org, email@example.com types of purposes etc.
From a user perspective it's easiest if the shared mailbox is accessible from the users own mailbox, and the ability to drag and drop mail items beetween folders is preserved. This is default behavior in Outlook 2010. But what if the user is using his/her Outlook Web App (OWA) for working with mails?
In OWA two methods exists for opening other users folders:
Each has its advantages and disadvantages.
Method 1: Explicit logon
It will open the Shared Mailbox in a new window and you cannot drag and drop mails between the two windows. But the subfolders of the Mailbox's Inbox are visible and you can drag mails from the Inbox to its subfolders.
To open a Mailbox using Explicit logon:
1. Click your name in the top right corner of Outlook Web App
2. Type the alias of the Shared Mailbox
3. The Shared Mailbox opens in a new window. No drag and drop capabilities between your Inbox and the Shared Mailbox
Method 2: Mailbox Delegate Access
It will open the Inbox in the same browser window and you can drag and drop mail items between your folders and the Inbox of the Mailbox. But the subfolders of the Inbox are not visible.
To open a Mailbox (Inbox) using Mailbox Delegate Access:
1. Right click your name in the Folder list (your mailbox) to the left and click Open Other User's Inbox...
3. The Shared Mailbox opens below your primary mailbox in the Folder list
4. AND you can drag and drop mail from your Inbox...
... to the Shared Mailbox (and vice versa)
Best of both
So what to do if you'd like to have the best of both methods? Being able to drag a mail from your inbox to a subfolder of a Shared Mailbox's Inbox. Well - for now you will need to do a litte tab juggling in you browser.
You now have a working environment - you can drag emails from your Inbox to the Shared Mailbox (Inbox) in the first tab...
... and you can drag mails from the Shared Mailbox (Inbox) to its subfolders in the second tab
I hope this will serve as an inspiration to you for using Shared Mailboxes even if you are not using Outlook 2010 - the browser experience is quite userfriendly too :-)
