Fast Way to Export Office365 Shared Mailboxes to PST

A user’s account in Outlook contains the complete mailbox that has multiple folders to save emails and other data. The mailbox is created for a specific user by his/her name. But sometimes, a mailbox is required for some accounts that are managed by more than one user. A business requires multiple mailboxes that are meant to get emails directly to the business-like contact, complaints, careers, etc.

A business manager may also require some dedicated mailboxes to share information between the team members, colleagues, and clients. A shared mailbox is an answer to all these requirements. The shared mailbox does not have its email address or password, so the user cannot access it directly. The Exchange or Microsoft 365 Administrator creates it and assigns the permission to the user. Then the user can log in to Outlook and access the shared mailbox.

How to create a shared mailbox?

The Exchange Administrator can create a shared mailbox in the Exchange Administrator Center –

  • In the Recipients category, click Shared and click Add button with the plus icon.
  • In the empty fields, enter a Display name and the email address.
  • The next step is a permission that you can assign to the mailbox and also select the users who are granted the permission.

NOTE – There are three types of permissions for each mailbox.

Full Access – Full Access permission grants the full authority to the user over a shared mailbox. The user can create calendar entries, read, write, edit, delete or modify the email messages. Users can also create new contacts and tasks. The noteworthy point is that the Full Access permission does not allow the user to send emails through Shared Mailbox. To send an email, the user should have either Send as or Send on Behalf permissions.

Send as – it is impersonating permission that facilitates the user to send an email. The recipient will receive the email on behalf of a shared mailbox account rather than the sender’s username.

Send on Behalf – Send on Behalf permission allows the user to send an email on behalf of the shared mailbox. For example, if Joey sends a message using Meeting Room no. 4, then the recipient will get the message as ‘Joey on behalf of Meeting Room no. 4.’

  • After selecting the permission, you can move forward and click the Add button to add users to will use the shared mailbox.
  • Click Save to save the changes.
  • Ask the user to restart their Outlook application and they will have a new shared mailbox in their accounts working separately.
