Hi. I own a small company. I’m getting the error code 0x80070021 while trying to backup my personal folders. Although, some of my mail accounts are working with it. I am not able to find any solution for the problem in Outlook, can anybody please help me ASAP. Thanks in advance.
Hi,
Usually, for MS Outlook Add-in this problem is occurred which it prevents Outlook from closing down. Follow below steps to resolve this issue.
If you receive error code “0x80070021” in Microsoft Office Outlook, the usual cause is the Microsoft Office Communicator because it is frequently tightly connected with Microsoft Office Outlook. Try closing Microsoft Office Communicator then see if it works. If this doesn’t work, try this one instead. In Microsoft Office Outlook, click “File” then select “Outlook Options” at the bottom. In “Options” window, select “Add-Ins” on the left pane.
On the right, at the bottom in “Manage”, select “COM Add-ins” then click “Go”. Now, in “COM Add-Ins” dialog, select “Search Email Indexer” if you see it then click “Remove”. Click “OK” then restart Microsoft Office Outlook. See if this works. If you don’t see this item listed, check for “Windows Email Receiver Index” instead and remove it.
