Get-LaMailboxFolderSize

NAME Get-LaMailboxFolderSize



SYNOPSIS

Retrieves each mailbox's: 1. entire TotalItemSize 2. and more specifically, TotalItemSize for just the

RecoverableItems folder





SYNTAX

Get-LaMailboxFolderSize [-userprincipalname] <String> [<CommonParameters>]





DESCRIPTION

Requires mandatory value(s) from the pipeline. Specifically, objects that contain the mailbox's

UserPrincipalName. A CSV is not mandatory as a command could pass the necessary information from the pipeline.

However, a CSV could certainly be used to break up large data sets.



Note: This function executes two commands per mailbox and could be subject to Office 365 throttling.

Therefor, for large tenants it is best to break up mailboxes into CSV's of 5,000 or less UPNs. For best

results, no more than 2 concurrent sessions of this function should be run. It may be necessary to contact

Office 365 support to have some throttling reduced.
