Question

Hello,

Is "Storage Used(bytes)" in reportRoot: getMailboxUsageDetail graph api report consists of archive mailbox size as well?

Similarly, is "Deleted Item Size (Byte)" from getMailboxUsageDetail graph api report consists of archive mailbox deleted items?

How frequently the report gets refreshed? Can we refresh it manually?

"Item Count" from same report, which folders items it counts of?

Please answer separately for each question.

Thanks in advance!
