What is the best task and meeting management solution?

Question

Yandex

Kind people, advise some solution for managing tasks and meetings (between employees) from a smartphone and PC. I will say right away that Outlook and thunderbird will not work, because we use Yandex mail with our own domain, and I don’t want to work with them without crutches.

Answer 1

Most of the solutions are cloud-based and paid.
You can plan, for example, in wrike or jira, depending on the specifics.
To tell the truth in one vial I know only at MS.
Usually, either for planning and managing tasks ( wrike, jira ), or for meetings, scheduling meeting rooms, video conferences ( webex, gotometting ), there is also a separate class for scheduling meetings with clients, usually as a crm module.
ms has a combine for this and that, office 365.
Simple tasks, mail, this is exchange plan 1
Tasks, the form of conferences, scheduling meetings, plus everything in the paragraph above and also web word and Excel, this is office 365 business basic.
There is also a project, it goes separately.
All this is in the cloud, the first costs 3500 per user per year, the second 4500.
But to be honest, this is not a fountain for tasks, since only todo integrates with outlook web, and only planer with team. And in the planner, the tasks only have no date (without time), and only group ones, and todo can see them, but there are no tasks from todo
in the planner, and only in todo there are personal tasks.
