Messaging record management (MRM) in Exchange Online helps in managing the records. MRM is possible through retention tags and retention policy. Here, we will talk about how to Create Retention Policy in Office 365.
What is Retention Tags?
Retention tags help in applying the retention setting to Office 365 messages and folders. These retention tags are used to apply the retention policy. There are three types of retention tag:
- Default Policy Tag
- Retention Policy Tags
- Personal Tags
Steps to create Retention Tags
Below are the steps to add Office 365 retention tags:
- In the Exchange Admin Online center, under compliance management, click retention tags.
- For creating retention tags, click the arrow beside the plus sign, a drop-down menu will appear. From the menu, the user can choose any needed option.
- Applied automatically to entire mailboxes (default)
- Applied automatically to a default folder
- Applied by users to items and folders (personal)
- After selecting any one of the above, a new pop-up window will appear. Enter the name of the tag; choose retention action, and the retention period. Then, hit the Save button.
Retention Action: There are three types of the retention period-
- Delete and Allow Recovery: It allows users to recover deleted items by moving data to the Recoverable Items folder in Exchange Online until the deleted item retention period for the mailbox database or the user is reached. It helps the user in recovering the data for the second time using the Recover Deleted Items dialog box in OWA. If the user has set the deleted item retention period to zero days, items are permanently deleted.
- Permanently Delete: Here, the user cannot recover the data once deleted permanently. If the Office 365 mailbox is on Litigation Hold, items are preserved in the Recoverable Items folder based on the hold parameter.
- Move to Archive: It moves the item to the User’s archive mailbox if it exists. If a user does not have an archive mailbox, no action is taken.
Using PowerShell:
New-RetentionPolicyTag -Name “DPT-Corp-Delete” -Type All -AgeLimitForRetention 2556 -RetentionAction DeleteAndAllowRecovery
The command allows creating a default policy tag to delete all messages in the mailbox after 7 years (2,556 days).
