- Office 365 (System Offices) – Managing Group Membership
You can no longer manage group membership from Outlook. Due to the one-way sync structure of UOFI AD > Azure AD group membership changes cannot be made in Outlook when the mailbox is located on Exchange Online. Alternatives are using ADUC to manage membership in UOFI AD, switch to an Office 365 group, switch to a Sympa listserv or contact your IT Pro.

- Office 365 (System Offices) - Calendar and Free/Busy
You may find that you can no longer see the details of calendars that are outside of your direct department if they have not migrated yet. You should still be able to see free/busy time. After all departments have migrated this will no longer be an issue. At this time being able to view free/busy times on a calendar outside of your department has been found to be inconsistent. Microsoft has been notified of the issue and we are hopeful for a fix soon.
- Office 365 (System Offices) - Shared Mailboxes
It is recommended to migrate shared mailboxes at the same time as your departments individual accounts. You will not have access to shared mailboxes that have not migrated. We encourage you to move these together to reduce impacts on workflows, etc.
- Office 365 (system Offices) - Skype for Business
- Outlook Integration Error or Exchange needs your credentials
After a mailbox is migrated to Exchange Online some Skype for Business clients receive a warning about Outlook integration, see exclamation marks on the Conversations tab, or a yellow bar about credentials. Be sure to use email@example.com for username. If that doesn't help, you can clear the client-side cache for Skype for Business.
- Lync 2010 is prompting to download and install a MSI file from Microsoft
This additional software install is required to allow Lync 2010 to connect to Exchange Online.
- Lync phone edition phones can't connect to Exchange OnlineOffice 365 will only allow TLS 1.2 connections (blocking the older SSL3, TLS 1.0/1.1) after October 2018 and currently there are no plans to update the older Lync phone edition IP phones software to support that type of secure connection. These phones will still be able to connect tour on premise Skype for Business systems, but visual voicemail, calendar access, and access to email contacts will stop working. While the University has approximately 4,000 of these phones, currently only about 100 of these devices are connected using this protocol and using these features.
