MSG files save Outlook emails, but sometimes they refuse to open due to corruption, version issues, or incorrect settings.

Common Reasons:

• Outlook not set as default
• File corruption or size issues
• Add-ins or temp file problems
• Version incompatibility

Quick Fixes:

• Set Outlook as the default app
• Repair or recreate the MSG file
• Disable add-ins & clear temp files
• Match Outlook version with MSG format
• Update Outlook & Windows

If manual fixes don’t work, use a professional MSG converter tool for accurate, bulk, and hassle-free access.
