Is this a licensing question? If you have Office 365, then it has to check in every so often to re-validate that your subscription is active. If you're using Office Pro Plus, then the license is perpetual and it doesn't need to check it.What's the issue if you can't access MS Office offline? Does a remote server cause the problem?
I had a MS Office Lifetime Subscription for my Desktop. Used it without any issues until last year when there were several issues with slowness, freezing etc when using the Excel spread-sheets. Then error messages kept popping up. Tried first to fix it with the Microsoft Office troubleshooting but it did not work. Then went online to diagnose it and it was the biggest mistake, as it took my Microsoft Office subscription offline and wanted me to input the Key to renew it. But the Lifetime key was not accepted as it was considered to have expired.....Really, a lifetime key expiring?Dumped M$ Office, Word, etc., for free OpenOffice and LibreOffice years ago and never had any problems.
You left out, updating received files and returning a modified MS format file. Interestingly, LibreOffice can read Microsoft Works documents and can save them as Word docs; something that MS Word cannot do.I'm a Linux guy. Dumped Windows years ago. Have been using free OpenOffice and now LibreOffice for years with no issues. Friends and businesses do send MS Office files etc., which LibreOffice has no problems converting over and opening. Worth giving it a try, it's free.
Absolutely. I used LibreOffice for probably 10 years now. But now I am almost always directly on google drive (google docs).You left out, updating received files and returning a modified MS format file.

Good to know. After converting the Excel to Calc., I noticed that it created over 21,0000 pages in one of the tabs. Was not straightforward to erase those unnecessary pages. So I had to copy and paste the spread-sheet into a new tab, and then erase that tab with the issue. Now it works fine. However, formatting some of the columns and boxes is not as straightforward. Guess, with time I should manage to decipher it.Excel is going to be the only potential problem depending on the feature set you use. There really is nothing with the power of Excel. If you're just using formulas in cells, it's probably fine. If you're using pivot tables, VBScript, complex conditional formatting, advanced filtering, or anything with PowerBI, there's no alternative.
