Hello, I'm a IT Consultant. One of our users has lost their calendar entries from 2013 August and older. We do have a recovery solution to get this data back, but to prevent this from ever happening again. Is there a option to do so?
What we so far figured out is that there might have been an issue with the sync between the device and the server. That in the case the phone found out it didn't have enough space for all calendar entries, it deleted the old ones instead of ignoring it. This could be wrong though.
We just found this out so the user does not know what type of phone he used when this occured. But the default mail app was used.
Any suggestions would be appreciated!
Thanks.
