Sometimes, It becomes more difficult to decide on which Office365 Plan to go for, It is completely depends on the requirement and anything missed on this might leads to unnecessary cost to the company.

Lets Consider, If customer has specific requirement about his Legal Compliance features (Data Loss Prevention, In-Place and Litigation hold) or Voice Mail and Third party fax integration, You can suggest any Enterprise Plans, this is the major difference between Business and enterprise plans. Remember “Archiving” is included only in Enterprise can be add-on for other plans.

Below is the mandatory checklist to be gathered before we acquire/enable new Office 365 tenant:

  1. How big the organization is?
  2. How many users are required?
  3. What is current environment? Exchange Version, Google, POP/IMAP etc.
  4. If current environment from Existing Office365, What is the current subscription? & has it         purchased from Microsoft (or) Partners?
  5. Do they have Office Installed? Which Outlook version?
  6. Do customer require advanced compliance features, like DLP, Encryption etc.

Note: Outlook 2003 is not supported to work with Office365, Outlook 2007 SP3 or later is supported.

Office 365’s E3 and E4 plans are more explicitly a power user who routinely needs to use advanced analytical software like Microsoft Office Plus’s InfoPath, or who might need to take advantage of the document sharing capabilities that SharePoint offers. In respect to an executive who needs an onslaught of email capabilities, archiving and storage is available in almost an unlimited capacity. E3 and E4 also included with Office 365 Message Encryption for all other plans if customer requires encryption separate Azure RMS add-on to be purchased.

The only difference between the Enterprise E3 and E4 plans is that the Enterprise E4 one offers enterprise VOIP solution & Enterprise E5 with Office365 advanced E-Discovery, Customer Lock box, Advanced threat protection.
