Hi
So a really frustrating situation. I've always used outlook on browser and never had an issue. I open up 2 outlook accounts, one is for work and the other is my personal one. For some reason, today I haven't been able to save an event via the calendar. I keep getting the same error below 'could'nt create event, try again':

The weird thing is I am able to open up the outlook app on my phone and save an event on both my personal and work accounts without any issues. I can also edit and delete events via my browser! It's so frustrating. I've tried logging into my accounts on another laptop and have the same issue! It appears it definetely something to do with my accounts but I'm unsure how it's happened. I can't find an answer anywhere on google to fix this issue!
I've got a lenovo laptop, I've updated my software settings. I've restarted my laptop, cleared the cache etc etc. I've literally tried everything!
Can anybody please help me as it's so frustrating
