The name cannot be matched to a name in the address list
The error message in Outlook hints, the target mailbox you are trying to access or find is not listed in the Global Address List. This may be due to the incorrect configuration of the Hide from Address Lists box in Mailbox properties. So, to fix it, take the following steps! Let’s cover the above process in a bit of detail now! Go to the Exchange Admin Center. Enter your login details to open the Dashboard.
From the left panel, select the Recipients option. Then, switch to the right-pane and double-click the shared user mailbox to edit it.
Under the General menu, look for the ‘Hide from address lists’ option. If the box against the option is selected, uncheck it and hit the Save button. Now proceed to set up the OE365 account in Outlook. When done, go back to the Exchange admin center and check the box marked against the ‘Hide from address lists’ option. Following this, the user should appear in the Outlook address list. That’s all there is to it!
