we have user that has 105k items and it looks like half are in the calendar we can't seem to figure out why the item count is so high any ideas? thanks tr

There are a few checks that you could run. 1. Check whether the user has recurring / duplicate appointments in the calender amounting to high item count 2. Check whether after exporting the calender to a pst; removing the calender from the users' outlook and importing the calender back changes the item count and 3. Move the mailbox of the user to a different store and check ( if there are any errors or discrepancies, they are left behind while moving the mailbox )

thanks for the input! basically I did step two and the count went from 105k items to 52k items still very high. The user did have recurring items in the calendar but I don't know how they could add up to 53k items! The numbers sound strange they are basically half the 105k total52k -> 53k very stumped on this! The next largest item count for a user on our server is 12k the average is 4k! tr

Clarify: the total number of messages is higher than normally in the calendar Collect info: 1. Which type of mail account does user use, exchange account or POP3? If its exchange account, which mode does user use, cache mode or online mode? 2. Confirm version: exchange and outlook Troubleshooting: Use MFCMAPI to confirm the count of calendar, it can see mailbox in raw data a. Launch MFCMAPI on users client PC b. Session menu->choose Logon and Display Store Table->choose affected users profile in jumped window c. On the top-pane, double-click users mailbox and go to next window d. In the next window->expand Root Container->expand IPM_SUBTREE->double-click Calendar e. Use Shift button and mouse to select all items f. Check the number of items in the right-below corner status bar Explanation: The RMTable property limits the number of appointments that can be saved on a Calendar to 1360 appointments or to 32 KBs of appointment data. Microsoft recommends that we do not exceed this limitation in a Calendar folder file. As when its exceeded we are not able to guarantee results nor can we say when you will begin to run into problems.
