Smart email boxes updates will not save after restarting email
any changes (add one, delete one, change rules) I do to smart email boxes will not stick. After I quit and restart all changes are gone. I have deleted multiple plist files under v8 of maildata under library. The SyncedSmartMailboxes has a data modified date of sep 7, 2018 1046 am and will not change. If I remove this file and start email a new file is not created. OS 11.1 Big sur, using a mac pro late 2013. I have reindexed. Any clue how to fix this issue? Note I have 3 email accounts, one iCloud, one gmail, and one comcast and I have email on my mac.
Mac Pro, OS X 10.11
