Verify Folders on Webmail and Repair Outlook Profile
Check if the folders exist on the Exchange server to isolate the issue, then recreate your Mac Outlook profile to force a fresh synchronization.
Outlook for Mac relies on a local profile to cache your Exchange data. If this profile becomes corrupted during a reinstallation or hard drive migration, folders may not display locally even though they exist on the server.
Open your preferred web browser and sign in to Outlook on the web using your Exchange or Microsoft 365 account credentials.
Check your mailbox folder list in the web browser. If all missing folders are visible here, the issue is strictly isolated to your local Outlook for Mac client.
Close the Outlook for Mac application. Open Finder, navigate to Applications, right-click on Microsoft Outlook, and select 'Show Package Contents'. Navigate to Contents > SharedSupport and double-click to launch 'Outlook Profile Manager'.
Click the Add (+) button to create a new profile and give it a name. Click the gear icon at the bottom and select 'Set as Default'. Restart Outlook and proceed to add your Exchange account again to initiate a fresh sync.

Frequently Asked Questions
Why are my Exchange folders missing after upgrading my Mac hard drive?
When a hard drive is replaced and Outlook is freshly installed, the local cache is completely empty. Outlook must resync all data from the Exchange server. If the initial sync is interrupted or the profile configuration is corrupted, some folders may fail to display.
Can I recover an Exchange folder if it is missing on the webmail interface as well?
If the folder is missing from Outlook on the web, it means it is no longer active on the server. You can check the 'Deleted Items' or 'Recoverable Items' folders. If it cannot be found there, you must contact your IT administrator to perform a server-level restoration from a backup.
How long does it take for Outlook for Mac to sync Exchange folders?
The synchronization time depends heavily on your mailbox size, the number of folders, and your internet speed. It can range from a few minutes to several hours. It is recommended to leave the application open and connected to a stable Wi-Fi network to allow the initial sync to complete fully.
