I recently had the experience of exporting PST's from Office 365 using Outlook 2013. After adding the, what I thought was, proper permissions in Exchange Online, I wasn’t able to open the mailboxes I had given myself full access to. Every time I tried to open the mailbox, the following error message would appear:

In the end, the problem was related to the AutoMapping function of Exchange and Outlook. To solve the problem I had to do the following things:

1. Connect to O365 using your local Powershell Connection: Connect to Exchange Online PowerShell

2. Remove FullAccess permissions for the affected user from the shared mailbox:

    Remove-MailboxPermission (SharedMailbox) -User (UserAccount) -AccessRights FullAccess

3. Add Full Access permissions back on, but make sure you set AutoMapping to FALSE!

    Add-MailboxPermission (SharedMailbox) -User (UserAccount) -AccessRights FullAccess -AutoMapping $false

This solved my issue, and hopefully yours.
