Slack Business enhances team productivity through seamless integration, advanced organization, customizable notifications, and an intuitive interface.

Microsoft 365 Business integrates well and improves communication, cooperation, and security.
The subscription model of Microsoft 365 Business is beneficial since it provides continuous updates, including functional updates and transformations of the product.

Featured Reviews

CharlesBrewer - PeerSpot reviewer
Price and reliability need improvement while general tasks are streamlined
The pricing for Microsoft 365 is too high, and quality-wise, it does not meet high standards. The operating system is outdated and inadequate. Microsoft has very poor security, and Defender is ineffective. In terms of collaboration and file sharing, OneDrive is very clunky and has frequent sync issues. It also crashes a lot and is unreliable.
Awais Mehmood - PeerSpot reviewer
Automation features and user-friendly interface support seamless communication
Slack is very supportive in terms of communication between my colleagues and clients. While working with the reimbursement feature, I found the automation capabilities on Slack to be incredibly useful, allowing me to automate messages for specific dates or times and even to greet someone on their birthday. I haven't specifically used the channel organization feature of Slack, as I am added to channels, but I use it with Airtable, which automates notifications to a specific Slack channel when a user fills out a form on our website. In my experience, Slack is a stable product for communication, and I appreciate its automation features and integration of AI capabilities for enhancing specific functions.
