Hello,

I am looking for information on how to configure item retention for public folders/public folder mailboxes in Exchange 2013.

I have migrated the public folder hierarchy successfully from Exchange 2010 to Exchange 2013.

The public folder item retention used to be managed on a per folder basis using the "(LocalReplicaAgeLimit) Age limit for replicas days" parameter in Exchange 2010, and I found this worked quite well in removing items that had passed the configured expiry threshold.

The folders that needed a different age limit setting were exempted from inheriting the public folder database defaults, and granted a specific value.

These settings have not been carried over during the migration however, so now all public folders are inheriting the organization defaults for retention - which is $null.

Now that the public folder hierarchy is on Exchange 2013 and is mailbox based, what is the recommended method for granular public folder item retention.

I see that each folder the following settings can be configured Limits > Age Limits: Age limit for folder content (days) which looks like the setting I would need to configure, however, the technet text surrounding this parameter states:

Cmdlet: Set-PublicFolder

Parameter: AgeLimit

The AgeLimit parameter specifies the overall age limit on the folder. Replicas of this public folder are automatically deleted when the age limit is exceeded.

Does this mean the folder gets deleted once the limit has been reached - or just the items within?

Now that public folders are mailbox based, what effect (if any) do retention tags/policies have on public folder mailboxes - can item retention be managed this way?

Thanks

Hi Matt,

The AgeLimit parameter in Set-PublicFolder cmdlet is based on folder level.

The AgeLimit parameter in Set-Mailbox cmdlet is based on mailbox level.

For more information on how to set retention policy for public folder, please refer following article:
