I have the same issue! What is the permanent fix????

Hello,

Is this issue fixed?

Thanks,

Not sure why the issue affects each tenancy differently. If you have access to your Admin Center you can view the status of the issue under 'Admin Center > Health > Service Health', otherwise you might have to contact who ever manages your account.  Aside from the workaround that has been mentioned in previous messages. Using Microsoft mail app works as well.

I had mine fixed Last week straight and thought it would be fine from then, but now it all started to have issues again.
