Windows 10 and Office 365 Issue

[EvLPhenom]

Hi All,

 

Wasn't sure where to put this so please feel free to move it.

 

I have a very strange issue that has been brought to my attention and I have no idea what is causing it.

 

At one of my schools the head teacher has shared her Office 365 Calendar out to all staff and uses it as a whole school calendar. We have recently upgraded all staff laptops to Windows 10 Edu and since then no one can add events to this calendar. All staff have editor rights to the calendar after checking the permissions but when using the calendar online through Chrome or Edge it will not allow anyone to add events. If you create an event and try to select the calendar from the drop down box it isn't there, its like it doesn't exist. This even happens for the head teacher.

 

Any suggestions are more than welcome as i feel like i am going around in circles with this one.

 

Thanks

 

Andy
