Outlook Storage Full Despite Deleting Everything

mynameiskitty, Hi Kitty, if your Outlook is showing full storage despite deleting all emails, there might be other items consuming space. Here are some tips to help you:-

1. Try to Empty Deleted Items Folder for that you've deleted emails, they might still be in the Deleted Items folder. Empty this folder to free up space.
2. Check Other Outlook Folders for that ensure all other folders in Outlook (Sent Items, Drafts, Junk Email, etc.) are empty or have been cleared out.
3. Large attachments in emails can consume significant space. Go through emails and remove any large attachments.
4. Calendar, Tasks, and Notes for that check these sections to see if there are any items consuming space. Clear out unnecessary entries.
5. Compact Outlook data files (OST or PST) can become fragmented, leading to wasted space. Compact the data file to reclaim space:

   - Go to File > Account Settings > Account Settings.

   - Select the Data Files tab.

   - Choose the data file and click Settings.

   - Click Compact Now.

1. If you have multiple accounts synced with Outlook, check their storage settings. Sometimes, other synced accounts may contribute to the storage issue.
2. Archive Old data emails and data to reduce the size of the main data file. This moves older items to a separate archive file, freeing up space in the main data file.

Hope this will resolve your issue.
