What Causes Outlook Error 0x8004060c?
1. Compact the PST file
Outlook reduces the size of PST files by compacting it. When an email is deleted, the background process ensures that the file size of PST is also corrected by compacting it. The process of compacting can be initiated manually, however, offline Outlook Data File (.ost) could not be compacted.
2. Update Outlook/Office
Microsoft releases frequent updates for its products for improvement in features and to keep these products bug free and Outlook is not an exception. If the current error of Outlook is due to a known bug that Microsoft has already patched in its Updates, then updating Outlook/Office to the latest version may solve the problem.
