In Tech Tails #648 from February 3, we mentioned and discussed an ongoing issue common to people updating their Machines to 10.5.6. When launching Mail after the update, commonly they were presented with no Mail viewer.
If in that situation, one was to click on the Window item in the Menu bar and select Message Viewer, they would be presented with an empty inbox and all messages and information would seem to be lost. In issue #648 we gave a few steps for resolution of the error that required going into Terminal to fix the issue.
This week, after discussing that not-so-elegant fix with a customer, they contacted AppleCare Support who gave a new solution. The steps are as follows:
- Go to Users > [Your User] > Library > Mail and remove the two files: MessageRules.plist and MessageRules.plist.backup.
- After removing the files, launch Mail.
- Quit Mail once again and place those two files back into their original place.
I have not yet verified this fix at the present time, but the customer who sent it to me verified that this indeed fixed his issue.
