Exchange archiving report Reporting wrong value

Hi,

Ca anyone check if they having the same issue, please?

In the Exchange archiving report, I notice that "Size of items in Deleted Items folder (KB)" is showing the wrong value for some mailbox.
Example:

Mailbox display name: Mailbox1
Final estimated mailbox size (KB): 87 549 524
Initial size of mailbox (KB): 87 549 620
Size of items in Deleted Items folder (KB): 3 391 914

It says the Mailbox has more than 86GB and the size of the deleted is ~3,2 GB.

The Exchange reports that the mailbox has more than 86GB and the 85244MB (>80GB)

Get-MailboxFolderStatistics «mailbox1» -FolderScope deleteditems | where FolderType -eq 'DeletedItems'  | foreach FolderAndSubfolderSize 
PS:> 83.34 GB (89,489,947,359 bytes)

I checked all mailbox, and this issues only happen when the result is bigger the 4gb (4096 MB, number in binary '1000000000000', I think its only work until 4095 '111111111111'), so I don't think is a regional setting problem (Comma vs dot).

We have:

• Enterprise Vault 14.1
• Exchange 2019 (On-premises)
