Cannot display the folder error in Outlook
โ„น๏ธ

The error "Cannot display the folder. Outlook cannot access the specified folder location. Could not open the item. Try again." is frustrating but usually straightforward to fix. Try Option 1 first โ€” it resolves the issue in most cases.

1

Option 1 โ€” Delete or rename the OST file

In Outlook, click File > Account Settings > Data Files to find the location of your OST file. Then close Outlook completely.

Navigate to the OST file path โ€” typically:

C:\Users\YourName\AppData\Local\Microsoft\Outlook

Find the .ost file and rename it to .bak or .old (or delete it). Restart Outlook โ€” a new OST file will be created automatically and your mail will resync.

Option 2 โ€” Create a new Outlook profile

If Option 1 doesn't resolve the issue, create a new Outlook profile:

  • Press Windows Key + R, type control and press Enter
  • Find and click Mail
Mail option in Windows Control Panel
  • Click Show Profiles
Show Profiles in Outlook Mail settings
  • Click Add and give the profile a name (e.g. "New Profile")
  • Complete with your email details
  • Select Always use this profile, choose the new profile and click OK

Launch Outlook โ€” your profile will open and begin downloading mail.

Frequently asked questions

What causes the 'Cannot display the folder' error in Outlook? +

This error is usually caused by a corrupt or oversized OST file โ€” the local cache file Outlook uses to store a copy of your mailbox. Renaming or deleting the OST file forces Outlook to create a fresh one.

Will I lose my emails if I delete the OST file? +

No. The OST file is only a local cache. Your emails are stored on the mail server (Microsoft 365 or Exchange) and will be re-downloaded to the new OST file when you restart Outlook.

How do I find my Outlook OST file? +

Open Outlook and go to File > Account Settings > Data Files. The path to your OST file is listed there. It is typically located at C:\Users\YourName\AppData\Local\Microsoft\Outlook.

What if deleting the OST file doesn't fix the error? +

If the OST fix doesn't work, try creating a new Outlook profile via Control Panel > Mail > Show Profiles > Add. This gives Outlook a completely fresh configuration.
