Outlook Folder Emails are gone.

Question

Hello,

I was looking at some older files in a folder that I file Emails in and I have noticed that the Emails are all gone. This is also happening in a couple of my folders. How can I retrieve the Emails? They are not archived or deleted either.

Thanks.

Hello,

if you have an Exchange Server in use, this behavior may be due to the setting Keep email in offline mode in Exchange cache mode being configured to a value other than All. For example, the following screenshot shows a profile that has Exchange Cache Mode configured and the Keep Offline Mode Email setting is set to the default value of 12 months.

In the default configuration, Outlook synchronizes only 1, 3, or 12 months of email with your Outlook Offline Data (OST) file from the Exchange server, depending on the size of your hard disk.

If the Email in Offline Mode setting is set to 12 months and there are email items in your Exchange mailbox that are older than 12 months, those items will only be in your mailbox on the server. Therefore, if you cannot connect to the Exchange server, you may not be able to retrieve items outside the range specified by the Exchange Cache Mode synchronization setting until you reconnect to the server.

If you need to change how many months of email to sync with your OST cache mode file, follow these steps:

1. Start Outlook.
2. On the File tab, click Account Settings, and then click Account Settings.
3. On the Email tab, double-click your Microsoft Exchange account.
4. In the Change Account dialog box, drag the Email in Offline Mode slider to the number of months you want, or to All to synchronize all email messages.
5. Click Next.
6. Click OK when prompted to restart Outlook to complete the configuration change.
7. Click Finish.
8. Restart Outlook.
