Question Outlook Deleted Data File

[djayjazz]

I am trying to help a professor at my college. Outlook Data File(.ost) was removed and now his emails are synced, but does not have calendars, contacts, etc. However, the web version of Outlook contains the correct information. How can I sync the web version to her outlook desktop app so she has the correct stuff? Any help is greatly appreciated.

She's is currently using Windows 10.

That is dst, which is not relevant. Thanks for that.

What caused the original removal of the .ost file?

Perhaps:

Date and time (DST) issues can cause syncing problems.

Is there some reason why the college's IT support is not assisting the professor?
