We have had an issue with spellcheck not working on outlook.com/owa for a while now.
In the past I contacted Microsoft support who told me to just spell correctly. I found if I deleted their local profile and created a new one in AD, when the new profile was created the spellcheck would be working again.
I now have 4 users where spell check doesn't work and my previous fix no longer works.
I've tried googling for an answer but this fault has been around for many years and all possible fixes point to obsolete parts.
So instead of contacting the useless support I thought I'd ask here instead.
Has anybody else come across this? or have any ideas? cos I've run out.
