Good for processing data in small volumes, but undocumented functionality leads to unexpected behavior

What is our primary use case?

I am a business consultant and have worked in business continuity for about eight years. I work for factories, banks, government, and other organizations. I use different methodologies that depend on the customer's requirements. I have found that Office 365 is one of the best tools for business continuity, for small companies.

Pros and Cons

  • "Many of the features in Office 365 are good, but I think Excel is a very good tool."
  • "Using Visual Basic, I have had a lot of trouble with relative paths when programming for Excel, and sometimes it is very difficult to debug programs."

What other advice do I have?

Microsoft Office is a basic tool in consulting. I have implemented macros, specialized Office tools, and applications for it using Visual Basic. I usually need to design tools for our clients, because I want to give them a really good product. It needs to be more than Excel, alone, because it has to be easy to enter data. There are also calculations that happen in the background, and we do not want the client to be harassed by things that they do not need to know. The mission of the Office is to do small computations. It is a tool for small documents and spreadsheets, and I think it's perfect…

Good stability and scalability but needs better features

What is our primary use case?

We use this solution for email exchange.

Pros and Cons

  • "It's very stable."
  • "There are several additional features we would like to see, such as advanced features of SAN protection in Office 365. The main thing is the SAN protection; we would like to see a lot of advanced features added because we had a lot of spam attacks."

What other advice do I have?

The advice I would give depends mainly on their requirements. If they need to minimize their administration, Office 365 would be an excellent option. On a scale of one to ten, one being the lowest and ten being the highest, I would rate this product a seven.

Detects patient data, like a social security number, in email attachments and triggers an alert

What is our primary use case?

We use this solution to detect if a user, physician, manager, or director have sent out their patient data.

Pros and Cons

  • "The functionality that is most valuable is the solution's ability to detect patient data in email attachments. Whenever a user sends out an email with patient data embedded in an attachment, it triggers an alert. The tool can detect a social security number and various other forms of patient identity. Emails are then automatically generated and sent."
  • "Improvements can be made to the products generic offering. It's not customized for health care. It doesn't understand the meaning of health care related concepts. Providing a greater degree of industry specificity would make the tool much more unique and valuable."

What other advice do I have?

The version we are using is very generic. It requires that you perform a lot of customizations. I rate this product a 7 out of 10. I give it this rating because it works but it's not sophisticated enough and not specialized enough for health care. It requires a lot of time to customize.

Convert pictures to PDF format with ease

What is our primary use case?

Our primary use case is for creating files, and typing projects and for converting Word documents to PDF format.

Pros and Cons

  • "Most of the work that seems not to work offline works perfectly with Microsoft Office 2013, like converting a Word document to a PDF file."
  • "The feature to convert PDF file to a Word document needs improvement as well as the feature to save the file automatically when typing, without using the save command."

What is most valuable?

The cloud service and Skype are the most valuable features. We also use the MS Word and Excel.

One to three years.

What do I think about the scalability of the solution?

We have five people in our office.

How are customer service and technical support?

Cloud-based management is valuable and software deployment is positive

What is our primary use case?

We use it throughout our business for email and documents. It has allowed us to stop maintaining SharePoint and Exchange installs.

How has it helped my organization?

It has allowed us to eliminate a lot of in-house infrastructure and has simplified our software licensing.

What is most valuable?

Cloud-based management is valuable and software deployment is positive. SharePoint, document sharing, and Skype have been helpful as well.

What needs improvement?

They should stop releasing new features and focus on making the existing ones work. Their support is so terrible and unusable except during dire emergencies.

For how long have I used the solution?

Three to five years.

Product helps us be more efficient with a standardized way of doing things

What is our primary use case?

We are using the cloud-based version. We use it in an office environment and also in a school environment. It is performing great.

Pros and Cons

  • "The technical support is outstanding."
  • "The product helps us be more efficient. It helps us to have a standardized way of doing things."
  • "There are some complexities to the initial setup if you use some of the more advanced features."
  • "It needs improvements around its compatibility with non-Microsoft products."
  • "They should do more testing before product releases."

What other advice do I have?

It is an excellent, stable solution for doing what we do in our business. The product has my highest recommendation. Most important criteria when selecting a vendor: reliability of the product.

Has been extremely reliable, stable, and deployment was simple

What other advice do I have?

We've been very happy with Office 365 so far. We're looking to see how else we can leverage the investment in Delve, Yammer, Forms, and other capabilities across the business.

What other advice do I have?

Adoption is key! Don't push it. Especially for users who are used to working with traditional tools, it will be hard to adopt a new way of work.

It is a very easy, logical set-up. It provides us with collaboration and security.

What other advice do I have?

Provide lots of training and roll out one app at a time for apps that are above and beyond standard Office apps. Reiterate that they can use cloud/desktop or both. Our users sometimes struggle understanding that the desktop apps have the same content as the cloud version.

Exchange Online and Skype for Business Online are valuable features.

What other advice do I have?

If you really need to move to cloud, compare all of the options, check your budget and requirements and subscribe to Office 365's trial pack, which is available for 30 days. Feel comfortable with the product. If you feel that this product serves your requirement for the money you are paying, you may subscribe to Office 365 Enterprise. If in case you feel that this would cost you too much (for small business organizations), you may look for other cloud solutions like Google Business Apps or Google Apps and other cloud-based applications. You may look in Google for other cloud-based solutions.

I like the release planning feature and their notifications about upgrades.

What other advice do I have?

First of all, I was an enthusiastic and an early adopter of this product. Microsoft has made the onboarding process impressively robust and my learning pains back then, would not be those experienced by someone arriving new/fresh today. Still, the primary domain is something that one should give some consideration to, as it’s a lock-in decision.

My most recent deployment went off without issue.

What other advice do I have?

You may need ADFS; you may need a hybrid environment. Not everything necessarily goes away. Also, user management continues; it just moves to a new place (hosted/the cloud).
