I am having difficulty in searching my mails in folders of Outlook 2010... no error is generated....

Do you mean there is no result returned when using instant search in Outlook? If this is the case, it may be caused by several reasons, such as broken indexing, corrupt Outlook data file.

To troubleshoot the issue, please first make sure the indexing is complete. To verify this, please follow:

1. In Outlook, click in the Search box.

2. Click the Search tab, click Search Tools, and then click Indexing Status.

3. When the Indexing Status dialog appears, you should see the following:

Outlook has finished indexing all of your items.
0 items remaining to be indexed.

If Outlook has not finished indexing all of your items, note the items remaining to be indexed, wait 5 minutes, and then check again. If the number of items did not decrease, continue to troubleshoot by using the steps in the following KB article:

Hope this helps.

Hello Stev,

Usually such issues occur if there is any indexing problem with your Outlook or if your Outlook PST file is corrupt as mentioned by Steve Fan. 

If you are facing the issue even after Indexing Outlook, then I would suggest you to run Inbox Repair Tool. This tool will repair and fix your PST file if it is corrupted. Follow the steps present in this article to run Inbox Repair Tool.
