1] Run Microsoft Support and Recovery Assistant tool
You can begin troubleshooting to fix the issue of some Default Folders missing in Outlook and Outlook on the Web by running the Microsoft Support and Recovery Assistant tool on your Windows 11/10 device – the command-line version of the SaRA tool is also available.
The tool can help you with Outlook if:
- Email in Outlook not syncing
- Outlook won’t start
- Can’t setup Office 365 email in Outlook
- Outlook keeps asking for password
- Outlook keeps “Trying to connect…” or gets “Disconnected”
- Shared mailboxes or shared calendars don’t work

2] Create Outlook.com email alias
This is more of a workaround than a solution. Before you try this workaround, first sign out of Outlook on the Web, and then sign back in and see if the missing default folders are restored. If not, you can create an Outlook.com email alias.
Having an email alias is very useful if you do not want to give out your main email ID to someone, and do not want to create a new Outlook email account – but instead manage the account from your existing account. This way, you can use different email IDs for different things easily.
