Outlook calendar tab slow to respond

I have a new PC laptop and it works really well. I am a heavy Outlook user (which

has been working very well on my new laptop until recently). I installed iCloud

on my laptop so that I could see my iCloud calendars in my Outlook but as soon

as I did that, literally the next time I used Outlook, the calendar took

several seconds (approx 45 seconds) to load. Once I wait for the 45 seconds the

calendar runs fine. If I then move to mail in Outlook and then back to calendar

(and I do this all day long) I encounter the same delay.

Can someone help me resolve this long delay please?

This problem exist already for more than 10 year. All versions of windows, outlook, icloud... had the problem.

As from the moment you install icloud on windows, and you want to use it (why not,

because solution, disable it, is not a solution), going to calendar few takes

ages..

I really don't understand that or Apple or Microsoft fixs this.

Saying.. it's 3th party (Microsoft) or it is not our software (Apple) is NOT a solution.

 I really wondering if Apple is testing this.. Some Developers need to make it I

thing.. but make it, not test it?

 I can't understand.

Fix this please!
