It is easy to find out how much storage space your Exchange mailbox takes up. This documentation will provide the steps to look-up Mailbox size for an Exchange account in Outlook Web Access (OWA webmail), Outlook, and Mail app on Macintosh.
NOTE: You can click the screenshot images to see them in larger view.
Note: This documentation requires an Exchange configuration in your mail-app. If you have not already configured Exchange please see Configuring Exchange for Mail App on Mac OS X Leopard (10.5) or Snow Leopard (10.6) or Configure Exchange for Mail App on Mac OS X Lion (10.7) and Mountain Lion (10.8) to configure Exchange first.
1. Run the Mail app to access your Exchange account:
2. Beneath 'On My Mac' right click the 'Exchange' account and select 'Get Account info'. You can also open this menu by clicking on 'Inbox' in the mail list and hold down the command key and press the 'i' key:
3. In the “Account Info” window that appears, be sure that the “Brockport Exchange” mailbox is selected in the mailbox popup.
4. The 'Messages on Server' tab should be open. It will take a few minutes for it to 'size' each mailbox. When the message circled in the picture below is no longer there, each mailbox has been loaded:
Note: This sizing of each mailbox may re-sync occasionally in order to stay up to date with any changes made to each mailbox.
5. Once each mailbox has been sized there will be a column with Mailbox name, number of messages in Mailbox, and the current memory usage or size of that Mailbox:
NOTE: Most users will have a quota of 1 gigabyte for overall usage combined. Be aware that one gigabyte = 1,024 megabytes. As long as you are using fewer than 1,024 megabytes overall, you are below quota.
6. If you do wish to slim down your mailbox, the list of folders in this window is a good place to start since it tells you which folders are using up the most space.
7. Close the “Account Info” window when you are done, to return to the Mail program.
Note: This documentation is for Outlook 2010. This documentation requires an Exchange configuration in Outlook. If you have not already configured Exchange please see Configuring Exchange on Outlook 2010 and Outlook 2013 to configure Exchange first.
1. Run Outlook, login, and be sure that you are connected to the Exchange server (check the message at the bottom right of the Outlook window).
2. Be sure that you are in the Mail section of the program (use the button at the bottom left of the window if necessary).
3. Right click your Exchange account email and select 'Account Properties':
4. Select 'Cleanup Tools' from the Account Information menu:
5. Select 'Mailbox Cleanup' from the drop-down menu:
6. In the 'Mailbox Cleanup' window select 'View Mailbox Size':
7. Each Subfolder size should now be listed. When finished select 'Close' twice:
8. The figure listed after “Total size (including subfolders):” is the size of your mailbox on the Exchange Server.
NOTE: The mailbox size is given by Outlook in kilobytes. Most of you will have a mailbox quota of one gigabyte, which equals 1,048,576 kilobytes, so as long as your mailbox size is less than that, you are below quota!
9. If you do wish to slim down your mailbox, the list of subfolders in this window is a good place to start since it tells you which folders are using up the most space.
10. After you are finished, close all the windows to go back to using Outlook.
Note: This documentation requires that you are logged into Outlook Web App. See Accessing Exchange calendar and email at home or on the road via Outlook Web App for instructions.
1. Be sure that you are in the email section of the program (use the button at the bottom left of the screen if necessary). Hover over your name located above 'Inbox' with the mouse (Name in picture No. Julius, do not push any of the mouse buttons). A box should appear indicating the amount of Mailbox space currently used. Here is an example:
Note: Most users will have a quota of 1 gigabyte. The mailbox size is given in megabytes in Outlook Web Access, so be aware that one gigabyte = 1,024 megabytes. As long as you are using fewer than 1,024 megabytes, you are below quota.
Unfortunately, you cannot see the space taken up by individual folders using Outlook Web Access, but you can do this with Outlook in the steps given above.
