hello Evangelos Rizos,

Thank you for your reply,

As i said If a mailbox with an auto-expanding archive reaches a total of 1.5 TB of data stored in the auto-expanding archive, no more data will be stored in the auto-expanding archive or moved from the main archive to the auto-expanding archive.

Microsoft Purview automatically adds more storage space when necessary" what's the limitation in that? Are there more specific details? That is mean additional storage space is automatically created until the mailbox archive reaches 1.5 TB. So, no more storage can be added.

The question was asked because some companies doesn't want to delete any of their mails. In the document says that " Microsoft Purview automatically adds more storage space when necessary" what's the limitation in that? Are there more specific details?

Hello Evangelos Rizos,

Good day!

Thank you for posting to Microsoft Community. We are happy to help you.

As far i know When auto-expanding archiving is enabled for a user's mailbox archive or a shared mailbox archive, Microsoft Purview periodically checks the size of the archive mailbox. When the archive mailbox gets close to its storage limit, additional storage space is automatically created and this process continues until the mailbox archive reaches 1.5 TB. The additional storage creation happens automatically, which means administrators don't have to request additional archive storage or manage auto-expanding archiving.  Extra storage space is added until it reaches a maximum size of 1.5 TB. It can take up to 30 days for the additional storage space to be provisioned.

If a mailbox with an auto-expanding archive reaches a total of 1.5 TB of data stored in the auto-expanding archive, no more data will be stored in the auto-expanding archive or moved from the main archive to the auto-expanding archive.

Then, processing can stop for sending or receiving email and other items. To reduce this risk and minimize liability for your organization, we recommend using Microsoft 365 retention policies to delete content that no longer has business value. Configure these policies to delete items after a specified period. If you're not yet familiar with retention policies that can automatically delete email and other Microsoft 365 items, see Learn about retention policies and retention labels.

Note: Auto-expanding archiving is supported only for mailboxes used for individual users (or shared mailboxes) with a growth rate that doesn't exceed 1 GB per day
