CAMBRIDGE GRAMMAR FOR IELTS says:
We can use may (not), might (not), could (not), must, can't be doing to talk about things possibly happening at a time in the future.
I used to think 'must' can't be used to talk about things possibly happening in the future. Now am I right in making this sentence:
She must be meeting Robert this time tomorrow.
Thank you in advance.
