In part one (see here) I mentioned a PowerShell script (Export_DistroGroup.ps1) that I wrote to export certain settings of distribution groups in preparation for migrating them to Office 365. 1. Gather data. I exported a list of all distribution groups and their properties to a csv file. Then I wrote a PowerShell script (Export_DistroGroup.ps1) to export key details to multiple csv files for each group, […]
I am most of the way through a hybrid-mode migration from Exchange 2010 to Office 365. There are a few stages in a hybrid migration. During the process, your on-premises Active Directory database and Exchange directories are synced to the cloud so that mailboxes that have been migrated still appear in the on-premises directory for mailboxes that have not migrated and vice versa. Distribution groups […]
Of course, this only works with a single column in the hashtable… Say you have a list of mailboxes in a hashtable, like this: $Mailboxes = Get-Mailboxes -OrganizationalUnit administration But for some reason (It doesn’t really matter why, does it? You just do.) you want a list of their User Principal Names in an array instead of the hashtable. You can do this like so: […]
A user has hit his maximum mobile device count on your Exchange server, but when you try to remove an unused device that hasn’t synced in over a year, you get this error: If you look at the details of the error in the wizard, you’ll notice that the ActiveSyncDevice ID includes the user’s OrganizationalUnit. If you check the user’s current OU, chances are very […]
I don’t know about you, but it really bugs me to see dead accounts in the ACLs of mailbox folders. I wrote this PowerShell script to clean them up whenever I see them. It gets a list of all of the folders in a mailbox, checks each one for any permissions entries where the username = “NT User:S-1*”, and removes those entries, leaving all others […]
I use a scheduled task to run a script very similar to this one every midnight to clean up log files on one of my servers. It deletes any files in c:\logs that are more than 30 days old and any files in c:\special\logs that are more than 7 days old. Just change the paths and retention times to suite your requirements. # xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx # […]
I have a number of complex PowerShell scripts for performing employee onboarding/offboarding, mailbox export request cleanup, and other tasks. Scripts that use the standard cmdlet set, the Active Directory module, or Quest Activeroles AD Management snapin worked fine, but Exchange 2010 and Lync 2010 cmdlets didn’t despite loading the Exchange Management and Lync snapins. Those cmdlets didn’t seem to do anything at all and the […]
