How is the age for public folder calendar, task and contacts determined?

jp flag

We are running Exchange 2016 on premise and the upper management wants to set an age limit for public folders. We have a lot of public folders with tasks, contacts and calendar items. How is the age limit (retention age) determined for these types of public folder items? There is a lot of information on how retention age is calculated for mailboxes but not for public folders.

There are two levels of age limits for public folder(Limits for public folders):

1 Organizational level: Use the DefaultPublicFolderAgeLimit parameter on the Set-OrganizationConfig cmdlet.

And you could run the following command to view this setting:

Get-OrganizationConfig | fl DefaultPublicFolderAgeLimit

enter image description here

2 Folder level: Use the AgeLimit parameter on the Set-PublicFolder cmdlet.

Run the following command to view the age limit for single public folder:

Get-PublicFolder -GetChildren | Select Name, AgeLimit


There is another age limt for deleted items in public folder too:

Besides, you could also view the age limits of a public folder in EAC:

The above answer only covers how to set age limits on public folders. What I wanted to know is if/when will contacts, reoccurring calendar items and tasks be deleted? Is it based on the date created or the age after a calendar item and task is expired? Will age limits delete contacts in public folders?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
