Title
Not getting data from all mailboxes when running reports. -
Description
Some reports look like they are missing Data and all my gathering tasks are completing successfully.
-
Cause
In an environment with multiple gathering tasks, When running reports if you leave the default of "most recent" for the Date when applying filters the report will display the results from the last gathering task only.
For example if you have 4 mailbox gathering tasks and you run the "Mailboxes |Sizes and Quotas | Mailbox Sizes" report and leave "most recent" as the Date filter the report will only show results from the Mailbox gathering task that ran last.
-
Resolution
Change the Date filter in the report to "yesterday" for the report to include information from all gathering tasks that ran yesterday.
