Upon successful Migration of Outlook, Outlook might have not registered the location to which the Data Files are saved on the computer. You need to manually add the location to which the Data File is present and open up Outlook.
Open Control Panel and rearrange the Settings according to Small/Large icons. Find “Mail” and click on it. Further, click on “E-mail Accounts…”. Now, under “E-mail” tab you would have your Email address displayed. Please select it and the path to which it’s Outlook Data File is saved to would be displayed at the bottom on the window. As the path is not registered, you might not be able to view it. Kindly click on “Change Folder” option on the lower left hand and click on “New Outlook Data File”. Rename the new PST file (For example: Test) and click OK. Further, expand the newly created PST file (i.e., Test) and select the “Inbox” subfolder and choose OK. Now, from the “Email Accounts…” window, click “Change Folder” option again for the same email account, select the original PST file (the PST file which was set before creating Test PST file), expand it, select Inbox folder and choose OK. Close all the open windows, open Outlook and try to Send/Receive.
