I am having the same issue. Quite frustrating. Outlook just freezes. How can MS still be pushing apps out with such a fundamental floor as excessive resources usage.
MS takes away Skype, makes us use SFB and ensures we cannot share contacts and then give us Teams which is rubbish.
Sick to death of MS dictating how, when and what we use.... sigh. Wouldn't be so bad if it was stable, reasonable costs and simple to use. and you keep changing stuff everytime you put our a fix or release and changing stuff that just does not need to
change - moving icons around, hiding the ones you use all the time, etc, etc.
We're only a small business amoungst millions so just have to suck it up.
The "fix" suggested is complicated, not available to many non-admin users and is only temp until those temp get used again. Pretty poor outcome.
We will stop using it now and will look for a better, cheaper solution that works.
