We have received reports of customers who are getting errors when backing up individual user calendars. Currently this is affecting a small, but not insignificant number of users.
Our team has identified an issue where we are receiving a 500 error stating "An internal server error occurred" from Microsoft when retrieving folder data from certain calendars.
Currently, our engineering team is working on both identifying the root cause of the error as well as updating our logic to skip any failing items without causing the backup as a whole to stall/fail. If you are experiencing this issue or have any questions/concerns, please contact Dropsuite Support (support@dropsuite.com)
