Hi all Currently we are migrating from Lotus Notes mailboxes to Outlook group mailboxes, we have a few hundered group mailboxes to move over. We currently have 3 methods of granting the access to the mailboxes, however none are ideal. 1. Full access on a per-user basis. This would be a pain to administrate Users could not manage the access themselves Requires additional 'send-as' permissions but there is a long delay until this access is setup 2. Full access on a per-group basis This does not auto-map although it is full access The method of adding the mailbox is long winded, unintuitive and does not follow users to other computers Requires additional 'send-as' permissions but there is a long delay until this access is setup (or until I run the "clean-mailboxdatabase" command, however I can easily work round this with a scheduled task. 3. Full access and adding as an account This does not follow users around The display name in outlook is the full email address not the mailbox name To me, option two would be absolutely idea, if it automapped. I can't find any reason why this doesn't automap, and any other forum posts I have found have the same issue. As a great example, see this thread What best practice / methods are other people currently using for controlling access to their group / shared mailboxes?

Choose 1 and send instructions on how to map the mailbox. It really isn't hard.Ed Crowley MVP "There are seldom good technological solutions to behavioral problems."

Hello, After I test it, when you grant full access permission to the distribution group, the auto-map doesnt work. The three methods are fine, which methods is best which depends on your requirement.Cara Chen TechNet Community Support
