Office 365 – Quick Optimizations

I’ll be adding to this as I continue to work with O365, but for now I have two things I usually do for every tenant:

First, connect to O365 via Powershell.  If you don’t know how, please see my recent blog post

Disable “Clutter” feature for all mailboxes:

Get-Mailbox -Filter * -ResultSize Unlimited | Set-Clutter -Enable $false

Raise email message size limits for all mailboxes (and mailbox plans):

Get-Mailbox -Resultsize Unlimited | Set-Mailbox -MaxReceiveSize 75MB -MaxSendSize 75MB

Get-MailboxPlan | fl name,maxsendsize,maxreceivesize,isdefault

Set-MailboxPlan ExchangeOnlineEnterprise-XXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXX -MaxSendSize 75MB -MaxReceiveSize 75MB (use mailbox plan name from previous command)

Disable password expiration:

Log into O365 web admin portal (https://portal.office365.com)

Go to “Service Settings” –> “Passwords” and select “Passwords never expire”
