Exchange Maibox unlimited

Question

Hey all,

Some questions about quota management in Exchange mailboxes....

We have applied the default quota in 2Gb to our mailboxes.

However, we have a few users (in about 20% of them) above the quota, about 20% around the quota, and 60 % of the users utilize in about of 1Gb of 2Gbs.

My question is -

1. Is there a smart way to manage our quotas in the organization?
2. Is unlimited mailboxes reccomended?, Is this feature reccomended with cahce mode within outlook clients?

Thanks

Hi,
1 It sounds not so smart but just FYI, if UseDatabaseQuotaDefaults value is set to true, the mailbox will use the database quota rather then itself's. So you can move those 20% mailboxes to a new database with 3GB quota, 20% to another database with 2.5GB quota and leave the rest of them with 2GB. Steps for your referrence:
Use the EAC to create a mailbox database
Use the EAC to create a local move request

Set-MailboxDatabase db2 -IssueWarningQuota "2.8GB" -ProhibitSendQuota "3GB" -ProhibitSendReceiveQuota "3.5GB"  
Get-mailbox -database db2|Set-mailbox -UseDatabaseQuotaDefaults $true  

2 Better not, you can set some mailboxes with high limit, 10GB or 20GB.
Cache mode doesn't affect this, if your Outlook client shows different mailbox usage with in OWA, you should believe what OWA shows and recreate the profile.
