Have you ever had experience this kind of issue? You can access and see emails in your InBox when you are in Online Mode in Outlook but the emails vanish, when you are trying to access Outlook in Offline Mode.

I have come across this kind of issue while troubleshooting a customer’s issue remotely. I can see the emails in Inbox when I open Outlook in Online mode but no emails when I am in Offline mode. Surprisingly, I can see emails in other folders like Deleted Items, Sent Items etc… folders in Offline mode. Googled for the issue for couple of hours but no go. Created a new profile, OST but cannot find a resolution. Finally got a solution. You may try the following steps, if you would come across this kind of issue.

- Open Outlook in Online Mode.
- Check the Offline Folder Settings (Tools > Synchronize > Offline Folder Settings) and make sure all the options are selected like Inbox, Sent Item…..
- If you find all options are selected. Create a Temporary Personal Folder.(File > New > Personal Folder File)
- Now try to move all the email from Inbox folder to the Temporary Inbox folder. You must find there will be a corrupt email, which is causing the issue.
- If the email is not necessary, delete it and revert the emails to Inbox from the Temporary PST Inbox folder.
- Close Outlook.Now open Outlook in Offline mode, you can see you are emails.
