Thank you. I'll try. I'll inform you about result.

Hi, I've faced with problem when I tried to move mailbox from one database to another (both databases are in the same Exchange organization). When I initiated process of moving this mailbox all folders were moved but calendar wasn't. Process tried to move calendar’s object, but stopped when has reached a point 47676/1356 (It is also very strange, because the total amount of items is 1356, but process was stopped on the item 47676 ). I've tried to set "bad limits" to 50k and waited for 3 hours, but it didn't help. I've tried to move another mailbox to the same database and it has been moved without problems. I've tried to use a script instead GUI but a result was the same. I know that I can export calendar to a PST, clear it move mailbox and restore calendar from the PST (or archive), but honestly speaking I want to find better solution. Thanks in advance.

Hi It apears like there is some corrupted entry int he calendar change the view of the users outlook calender to catogory view and delete the exact one which is appearing in differnt icon. and Try to move the mailbox.
