Shared Calendar timings - Google -> Office365 -> Exchange

[mdrabble]

We maintain our calendars in Google, this has been done since before I arrived and a link was emailed out to staff so they could add to whatever they needed.

 

This mainly worked fine, except some staff had "issues" accessing the calendar.

 

This year, thought would make things easier and import calendar to their outlook calendar.

 

Currently using a Hybrid Office 365 and On-Premise Exchange with only staff remaining on On-Premise, which means the import process is a bit long winded up it works.

 

Google Calendar Shared as ical and imported to Office 365 Mail Account and all is well...... Salamander then take the Calendar and shares/imports to all staff accounts as an additional calendar. - All happy and no more hassle from staff!

 

Now here is the problem..... imported Google Calendar into Account on Office 365 and everything shows correctly.....

 

In Google Calendar - all day events show as starting as 0:00 (GMT+1 London) and finishing at 0:00 (GMT+1 London)

 

Office 365 account shows the imported Calendar as All Day (no times)

 

 

However - the all day events on the on-premise exchange are showing all day events starting at 01:00 and finishing at 01:00. Checked regional settings and timezones all set correctly (UTC 0 - London)

 

 

Anyone any ideas, thoughts, suggestions, answers??

 

Cheers.
