I started Skype for several employees - they constantly block accounts, what should I do?

Question

Microsoft

Registered about 8 accounts from one IP. A couple of days later, half of them were blocked for violating something that is not clear. I read that you need to indicate names, dates of birth, country and city. Indicated (the name was already indicated earlier). Blocked again. So in some other place they themselves deleted the specified data, instead of them there is just emptiness. What am I doing wrong? :)
In general, is it really possible to somehow organize a Skype connection for a small company so that you don’t have to check every day who was blocked this time?
I haven't had much experience with Skype before.

Answer 1

1. register your accounts by filling in all the fields normally and confirming your accounts by phone
2. 2FA
3. there is always a reason for blocking, and you can be answered in support, without a phone, the account login will be blocked in a month

Answer 2

Use telegram

Answer 3

I recommend that customers set up their own video conferencing server based on Jitsi https://jitsi.org/ to communicate with employees.
