Fix AD users UPN for Office 365 – Run Daily

Update -9/30/2016 — Included Users that gets migrated to O365, these can be detected as RemoteUsermailbox.

This script is very useful & is extension to my other script Fix Office 365 UPN

Fix Office 365 UPN

What it does extra is :

  • It can be scheduled to run daily & process the incremental changes
  • If there is change in SMTP address than also it can detect & update UPN
  • It also has a logic to take care of Users without mailboxes to change the default suffix for them to internet routable suffix.
  • It can slo be used to process all the users (just change the variable $fullrun = “Sunday” to the current day & it will execute to change all the UPNs)

This script you can use when you are done with all the UPN fixing & now you want that further fix is done automatically.

This can be utilized in environments where changing user provisioning process is becoming a challenge & you need a temporary or permanent workaround to mitigate the limitation of provisioning tool.

This is the logic of the script:

Logic for mailboxes:

If (weekday) _ increment

  • Fetch mailboxes that have integer values in extension attribute4 (to check if mailbox is employee mailbox, change it according to your environment)
  • Further filter it with newly created mailboxes
  • If fetching has issues or error out, script will exit & will not process further (example not able to access dc)
  • Further check if UPN matches windows email
  • If number of changes is more than 100 than also script will exit.
  • Update the UPN with windowsemailaddress
  • Log & report
  • Recycle Log & report after 60 days

If(weekend)_ full

  • Fetch mailboxes that have integer values in extension attribute4  (to check if mailbox is employee mailbox, change it according to your enviornemnt 
  • If fetching has issues or error out, script will exit & will not process further(example not able to access dc)
  • Further check if UPN matches windows email
  • If number of changes is more than 100 than also script will exit.
  • Update the UPN with windowsemailaddress
  • Log & report
  • Recycle Log & report after 60 days

Logic for Users without mailboxes:

 If (weekday) _ increment

  •  Fetch Users without mailboxes that have integer values in extension attribute4  &  UPN matches internal domain
  •  Further filter it with newly created Users
  •  If fetching has issues or error out script will exit & will not process further(example not able to access dc)
  • If number of changes is more than 100than also script will exit.
  • Update the UPN — update @internetroutabledomain
  • Log & report
  • Recycle Log & report after 60 days 

If(weekend)_ full

  • Fetch Users without mailboxes that have integer values in extension attribute1 or employeeid &  UPN matches internal domain
  • If fetching has issues or error out script will exit & will not process further(example not able to access dc)
  • If number of changes is more than 100 than also script will exit.
  • Update the UPN  update @internetroutabledomain
  • Log & report
  • Recycle Log & report after 60 days

Note: Exchange Shell & AD Shell is required for executing this script.
