Shared Mailboxes seem to pose a unique challenge for many customers because in VDC a Shared Mailbox can be backed up without consuming a VDC license, as long as the Shared Mailbox meets the following criteria:
• It is less than 49.5 GB in size.
• It does not have a Microsoft license associated with it.
When a Shared Mailbox reaches 49.5 GB in size, Microsoft attaches a license to it. Since at that point it has a Microsoft license, Veeam also requires a VDC license to back it up.
Some customers enable Archiving for their Shared Mailboxes. In this case, even if the Shared Mailbox is less than 49.5 GB in size, the Archiving feature requires a Microsoft license. Since at that point it has a Microsoft license, Veeam also requires a VDC license to back it up.
Many of our customers have hundreds or even thousands of Shared Mailboxes, but they don’t know how many of those are less than 49.5 GB in size and how many of them have a Microsoft license.
We created this document to help our customers find out the above information for their Shared Mailboxes with relative ease. Once the Shared Mailboxes with licenses or Shared Mailboxes equal to or greater than 49.5 GB in size have been identified, the customer can decide whether to exclude them from being backed up in VDC, or to purchase additional licenses to continue to back them up.
