The strategies in this post will help you fix the system folders missing from Office 365 mailbox. System folders are important for users but what if they are not visible to them. I am going to show you an easy fix to this problem.
Let’s dive right in.
The screenshot below shows that no deleted items folder is available in the user mailbox. It’s a hybrid environment and the mailbox is hosted in cloud.
When I tried to create a folder named Deleted Items, I received an error message that the folder already exists on a mailbox but is not visible for some reason.
Let’s try a quick fix to get rid of the issue.
- Download the 32-bit version of MFCMAPI and extract the file.
- Launch mfcmapi.exe and click OK through the intro screen.
- On the Tools menu, click Options.
- Make sure that “Use the MDB_ONLINE flag when calling OpenMsgStore” and “Use the MAPI_NO_CACHE flag when calling OpenEntry” are checked. Click “OK”.
- On the Session menu, click Logon.
- Select the Outlook profile for the affected mailbox, and click OK.
- Double-click the email address that represents the desired mailbox.
- Expand Root Container.
- Expand Top of information Store.
- Locate and select the folder that appears missing in Outlook, and check the value of PR_ATTR_HIDDEN to determine if it is set to True, as shown in the following figure.
- If PR_ATTR_HIDDEN shows a value of True, right-click the PR_ATTR_HIDDEN property and select Edit Property.
- Uncheck the Boolean checkbox and click OK.
- Make sure the PR_ATTR_HIDDEN property is False.
- Close all MFCMAPI windows, and restart Outlook.
The deleted items folder is now visible in the mailbox. These steps can be followed for other system folders such as Inbox and Sent Items.
