Replace MS Outlook 365 Calendar and Contacts with LO calc

Has my request been done previously?

Calc is a spreadsheet program like MS Excel. It has nothing to do with Outlook calendar and contacts.

If you intend to switch to LibreOffice, then you have all the options in LibreOffice as an equivalent to MS Office. See also:

Email and calendar function you can have separately, for example, with Mozilla Thunderbird.
In the search bar of your Internet browser, type: Mozilla Thunderbird

Your Microsoft product should be able to export your contacts and calendars into some commonly understandable file format. Mozilla Thunderbird can import text files (*.csv, .txt) and vCard files (.vcf).

Do I still need MS Office?
As long as you don’t have to pay for additional licenses and MS Office works, you should continue to use it in parallel.
And you may be able to continue using it as a document viewer after the subscription expires.
Editing documents is then no longer possible.

This is valuable information I did not know that an expired license can still be used to read those dodgy file formats. Since I never had any MS Office license in the past 20 years, I keep the MS Office document viewers which also work under Linux with “Wine”. The viewers for Word, Excel, Powerpoint are no longer downloadable from the MS web site.

But it wasn’t “grown on my dung” either, see:

Want to try LibreOffice - #3 by EarnestAl

I just like to compile valuable information.

Just one of the hazards of buying a Windows computer, trial versions of MS Office that take over file associations at regular intervals, even from licensed versions of MS Office. If you accidentally open the trial version by double-clicking one file, it triggers the one month countdown and next update they say they can be used as viewers only. Now that I am a grumpy old man, I uninstall them when they spring into action.
