Pros

Very positive experience - any successful business would find significant efficiencies and opportunities by moving to 365.
I love how secure the platform is, the software is easy to navigate. I love the fact that it is accessable worldwide.
We utilize all that the product has to offer on a daily basis and are quite happy with the product. It helps us manage our business better and provides the tools necessary to communicate effectively.

Pros

This is a good solution to be able to send an occasional fax as the technology has been largely replaced by email.
Easy to use and convenient. You receive it like a scan and could save it as a PDF.
Excellent, Reliable Solution for Receiving Faxes.

Cons

This is the sort of thing the hard drive resident application never struggled with. Conditional formatting layered up is the sort of thing that causes problems.
Sometimes i get logged out and have trouble logging back in. This is very rare but can be confusing and upsetting as everything is on there.
I hate, hate, hate, hate the fact that you cannot install each app on its own. It is pointless to force people who only need Excel or Word to install EVERYTHING.

Cons

I was billed for 3 years of service that I didn't use. I had proof of cancellation but was told no refund because I emailed my request to cancel to the wrong company department.
Customer support is slow, sends you in circles, and gives the wrong answer almost every time. Chat disconnects constantly and they give you the wrong phone numbers to call.
It's 2019 and the way efax does business is completely unacceptable. Once you give this company your credit card, they make it very hard to take it back.

I use this daily at work to access corporate forms and share files with my team.

Pros

I appreciate the ability to check my personal work email and share files in the same place. We use this produce in tandem with the rest of the Microsoft Office products. Great ability to organize files and accurately restrict access to the correct set of files per person.

Cons

This product is not as flexible as some other file sharing products, but for a company of our size (500+) it is probably one of the best options for our needs. Some times it is too rigid for my preferences.

In Microsoft 365 I daily use planner and everyone in the company can create a planner and assign tasks to each other. Sharepoint is very helpful as everyone can work in the same things at same time.

Office sets the bar high

Reviewed 3 years ago

We use it every day in a corporate setting, as is expected for all businesses.Never fails.

Pros

Office 265 is the suite that every competitor looks to re-create. It has all the programs needed for a corporate setting (excel, office, word, etc.) and is available bot online as well as a software app and mobile apps. We use it on all platforms and it would be tough to switch away.

Cons

There was a big update about a year or two ago that threw everything off with the way dates worked, and we had to re-haul all our files to conform. Once it was done it worked again, and our only complaint now is the way it scrolls diagonally on a trackpad which is extremely annoying.

Complete package of features you don't even know exists!

Reviewed 3 years ago

I started using Office 365 due to the migration of the company's license type, but over the months I discovered the tools like Planner, Teams, Sharepoint etc. With sharepoint it was possible to create several solutions to digitize processes (forms) and attach workflows to automate the approval steps. Teams is a complete communication tool!

Pros

Office 365 offers a complete suite for various types of demand. In addition to the traditional office applications, I highlight Teams and Sharepoint. Products that are integrated with various office products and facilitate the publication and organization of documents.

Cons

To create the Federation and use your corporate email, do a little work. but after everything is set up, it works well

eFax Corporate

Just no

Reviewed 5 years ago
Pros

I suppose for big corporations (or law firms, where I once worked and eFax supplied everyone with their own fax line), this is a good product. However, even when I used it at the law firm, I did not always get notification as I should have, or as fast as I should have, of the receipt of a fax. Or confirmation of a fax. It's nice to have the history of the faxes you've received, so you can go back...

Cons

Expensive, shady "free trial" that bills you no matter what, doesn't offer anything in terms of increased efficiency or performance that I can't get from using a free or already installed on my machine service.
