In any email environment where quotas are enforced, requests to increase quotas are a regular occurrence. The fact of the matter is storage costs money and therefore must be managed in a meaningful way. There has to be some kind of process or mechanism to determine if a quota increase is justified. Typically quota increases are a result of poor mailbox management. One way to help users is to analyze their mailbox for or with them.
For example, do they have a huge Deleted Items, Sent Items, or Calendar folder?
The Exchange Management Shell offers some built-in tools to accomplish this task. Manipulating the data makes it easier to identify quota bottlenecks.
Step-by-Step Instructions:
| param($alias = $(read-host alias))Get-MailboxFolderStatistics $alias | FT FolderPath,ItemsInFolder,@{label=”FolderSize (KB)”;expression={$_.FolderSize.ToKB()} }Get-MailboxStatistics $alias | FT ItemCount,StorageLimitStatus,@{label=”TotalItemSize (KB)”;expression={$_.TotalItemSize.Value.ToKB()} },@{label=”TotalItemSize (MB)”;expression={$_.TotalItemSize.Value.ToMB()} },LastLogonTime |
Results: For this example, I’ve used my own account (dave.rowe). You will see in this example that my Sent Items is quite large. There are a couple of other folders that could be cleaned up as well: Austin Fun, SA Fun, RSS Feeds, etc. (Note: I’ve hidden some folder names in the image to protect privacy.)
