in the getMailboxUsageDetail api
GET https://graph.microsoft.com/v1.0/reports/getMailboxUsageDetail(period='D7')
in response we get
so GetMailboxUsageDetail API includes which items?
like emails for specific users ? or it contains calendar items, contacts, tasks as well?
An API that connects multiple Microsoft services, enabling data access and automation across platforms
It's the total number of mailbox items, regardless of their type. So messages, calendar invites, tasks, etc.
but i got mismatch in count for outlook in my outlook there is calender invites that is count of 1 , and all mail count is maximum nearby 110 count including DiscoveryHolds hidden folder but from this report i got count like 2078
even though i tried task apis to found that is that any task remain but no there is no tasks that raise this itemcount this much high.
can you please help me to find out related item count .so i can cross verify my data once before developing further.
What does Get-MailboxStatistics show for that mailbox?
Also, keep in mind that the report as not current/real-time, on the screenshot above you're seeing data as of April 21st. If items have been added/removed from the mailbox since, the count will differ.
hello ,
actually i have added user for testing and for that user there is the fix data.so, that's sure that no data have been added /removed.
i think Get-MailboxStatistics used with powershell but i am using graph api for c#.
so still not able to get this diff. for itemcount
I'm asking you to check via Get-MailboxStatistics in order to verify the number of items reported for said mailbox. Not to use it for your solution.
So you have your answer then, the GetMailboxUsageDetail call is showing the correct count. Not sure how you got to the 110 number you mentioned previously, but obviously you missed some items.
