What are the disadvantages of Microsoft Teams?
Below are the bullets about the disadvantages of Microsoft Teams:

- Unnecessary consumption of storage
- Needs improvements over the notification.

- There are similar tools available from Microsoft.
Key-Takeaway: Limit in Microsoft Teams
- This limitation is of today (05th July 2020), as the popularity of teams grows day by day, Microsoft is dedicated to increasing these limits, so these limitations are not constant.
- If the number of teams meeting attendees is more, go for teams live event(limit is 10,000 – very soon this limit will be increased to 20,000) rather than scheduling the teams meeting(limit is 300).
