Import PST files to Office 365 Exchange

  • Assign Mailbox Import Export role to yourself (can take up to 24 hour to take effect, normally around 1 hour):
    • Exchange Admin Centre > Permissions > Admin Roles. Create a new role:
      • Name: Import / Export
      • Write Scope: Default
      • Roles: Mailbox Import Export
      • Members: <admin name>
  • Go to Office 365 Security & Compliance > Data Governance > Import. Click on New import job and complete a simple wizard (choose Upload your Data option).

Adopt orphaned Ubiquity UniFi devices

Ubiquity UniFi Cloud Key controllers are notorious for getting corrupted database after powering them off without clean shut down. Best course of action in such cases is to factory reset the Cloud Key and then restore from a backup up. If no backup is available you'll have to factory reset and reconfigure it from scratch. The main issue with this is that all UniFi WiFi Access Points and other devices that were previously managed by this controller will now be orphaned and appear in devices list as Manager By Other.


Migrating contacts and calendar from iCloud to Office 365

I had a task of migrating few thousands contacts and some calendars from Apple iCloud to Microsoft Office 365 (Exchange) system.

Importing Calendars was pretty straight forward:

  • Export all calendars in .ics format on a Mac via buit-on Calendar (select your calendar > File > Export > Export).
  • Open .ics calendar on Windows Machine with MS Outlook 2016 (which already had Office 365 account setup).
    • Go to View > Change View > List.
    • Drag all relevant appointments into Office 365 account calendar (I skipped appointments older than 12 month).
