How to Fix ‘Items aren’t Displayed in Shared Mailbox in Outlook’ Issue?

A shared mailbox allows a group of people to send emails from a common email address, for example, [email protected] or [email protected]. When a user, a member of the group, replies to an email sent to the shared mailbox, the email seems to be sent from the common email address, not from that particular user. This allows multiple users to access the same mailbox, thus facilitating collaboration and easy communication. However, the users having permissions to the shared mailbox can access and send emails as or on behalf of the common email address.

Sometimes, users face issues when they’re not able to see the items in the shared mailbox. There are several possible causes for the “Items aren’t displayed in a shared mailbox in Outlook” issue. In this article, we will discuss the causes behind this issue and see how to resolve it.

• Outlook will create a new OST file and download all the mailbox items from the server.

After synchronization is complete, check if you’re able to see all the items in the shared mailbox. 

Also, it is important to check for any missing mail items in the new OST file. If there are any, then use a professional OST to PST converter software, like Stellar Converter for OST to extract the missing items from the backup OST file and save them to a PST file, which you can import into your Outlook. The software can convert orphaned or inaccessible OST files of any size (up to 50 GB) to PST with complete integrity.
