Can’t sign in to Skype for Business

After migrating our organization from Lync 2010 on-premises to Skype for Business Online, I had one user who couldn’t log in no matter what I tried. She had Skype enabled in her msols license, her account was enabled, everything appeared to have synced ok, and she could log into http://outlook.office.com. The error message said “The user name, password, or domain appears to be incorrect. Ensure […]

Migrating Distribution Groups to Office 365, part 1

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 […]

Convert a HashTable to an Array

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: […]
