If you select the Use database age defaults option for a public folder, the default age limit does not work. Therefore, the contents of that folder never expire.
If you select the Age limit for replicas (days) option instead of the Use database age defaults option for the local replica age, the age limit works as expected. However, after you select the Age limit for replicas option, you cannot cancel the selection. This remains true even if you later try to select the Use database age defaults option.
Note To set an age limit for a public folder, use the Public Folder Management Console or use the Set-PublicFolder and the Set-PublicFolderDatabase
commands in Exchange Management Shell.
The issue occurs because
Database Age Limit is specified in days, but the value is saved in seconds. However, during online maintenance, the store process expects this value to be in days For example, if you set Database Age Limit to a value of 5 days, the corresponding attribute is set to 432000. When the store process reads this value, the value of the Use database age defaultsoption for a public folder is over 1,000 years. Therefore, the contents in the public folder do not expire.
This issue occurs because a function call is missed.
