Find out in this report how the two Content Collaboration Platforms solutions compare in terms of features, pricing, service and support, easy of deployment, and ROI."Using Office 365 has allowed us to go digital and onboard people seamlessly for working at home during the COVID pandemic."
"The most innovative feature of Office 365 is the Power Apps, which allows us to automate literally everything that we want automated. For example, sending attachments to specific folders on SharePoint, adding people's SharePoint when certain apps are performed, or emailing certain people at certain instances, such as when you've done a follow-up with the CRM and you need a marketing email to be sent out at a particular point."
"I like Office 365's usability."
"Cloud-based management is valuable and software deployment is positive."
"The product helps us be more efficient. It helps us to have a standardized way of doing things."
"I like all of the features."
"The cloud service and Skype are the most valuable features."
"The technical support is outstanding."
"The huddle feature that allows you to get on a call with a colleague is one of the best features of Slack."
"Slack helps me to read bulk messages."
"The huddle feature is valuable to me."
"One thing I like about Slack is the ability to change the color of Slack. It depends on my mood. When I'm having a bright day, I just change the background color of my Slack, which is nice."
"The product makes communication seamless."
"The most valuable feature is that we can easily integrate different workloads and the alerts are reliable. Also because it allows us to use it as a monitoring tool sometimes."
"Slack provides very fast communication."
"Overall, it is a good idea as it works better than most solutions out there."
"As a private user, I do not appreciate the cloud features, but I doubt that this is something Microsoft would consider a feature request."
"I rate the support of Office 365 a four out of five."
"There are some complexities to the initial setup if you use some of the more advanced features."
"Microsoft Defender for Office 365 could use some customization, but this area for improvement is trivial."
"If two people update the same file, it causes issues."
"Their support is so terrible and unusable except during dire emergencies."
"Security is still complex, but the admin console improving."
"In the next release, I would like to have a more intuitive tutorial."
"Slack tends to crash once a month."
"The tool has stability issues that need to be improved. We are not native English speakers and Slack needs to integrate grammar checks."
"For me, the only thing I can say is that every time somebody sent me an attachment, the attachment was listed somewhere, and then I had to open the conversation and go to the individual to open it. So there is no handy repository or an easy way to quickly look at attachments. For me, that was a bit difficult."
"It is difficult to navigate the tool when I log in to two devices and start a video call."
"It would be highly advantageous if it could incorporate calendar information from sources like Outlook or Gmail, providing users not only with meeting schedules but also a comprehensive daily agenda view."
"I think Slack could add additional features without making the solution slower or more difficult to use."
"The video calling experience on Slack needs improvement."
"Sometimes, the servers are not available."
