Hello,

No, the Exchange 2013 Server Role Calculator does not directly factor in the UM role. You will need to estimate and include UM into the user mailbox configuration fields. If you are currently using UM in a previous version of Exchange, this should already be included when you gather your usage statics in your current environment. The only impact the UM role will have in the design of the other roles would be the volume and size of emails that it adds.

To be clear, when you say "UM" are you talking about Exchange Unified Messaging (phone system integration) or were you referring to Lync? Lync is not UM and would have no impact on the Exchange Role Calculator.

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

All you need to do is determine the average number and size of voicemail messages per user and factor that into the usage data you plug into the Exchange Role calculator.

so that would be..

the average message size (KB)

total send / receive capability / mailbox / day

so if the current usage is 100 messages a day, this could increase to 150 messages per day.

it could add 100K to the average message size also

Correct. You have to estimate those numbers for your environment.

total number of tier-1 user mailboxes, this is the total number of mailboxes that fall into this category as opposed to tier-1 mailboxes that are active at any one time?

If you have inactive mailboxes, I would split those off into tier 2. If they are inactive, they should have message statistics of zero. All you are planning for is the space they will take up in the databases.

if there are 4300 mailboxes in total,

i suppose i need to clarify exactly what in-active mailboxes means.

Users can be either on leave or there is shift work,

These users are still part of distributions lists and receive email.  Their out-of-office will respond.  This is an active mailbox?

In the below tutorial, it specifies all users and not just those who are currently using their outlook

If you are able to split your users into different tiers, the calculator will be more accurate. For example, you may know one group send/receives 200 messages per day and other group only sends/receives 100. If you can't break down your users into tiers, just lump them all into a single tier and use an average.

So lets work on the basis that everybody is a tier-1 mailbox user..

There are 4300 mailboxes in total, which receive e-mail everyday and are responded to in some shape or form i.e. out-of-office etc

I would then have to put down 4300 as the active tier-1 mailboxes?

So i put the info into the calculator specifying 3 mailbox servers

RAM required per mailbox server = 3 x 48 GB
RAM required per CAS server = 3 x 24 GB

I am shocked !

Have you specified that you will combine your roles? Unless you have a specific reason to do so, you should not separate your CAS role form the mailbox server. Exchange is very memory intensive, so that number is not surprising.
