Outlook 2016 and Office 365
We have had intermittent issues with Outlook 2016 running on windows 10 1703 and 1709. Outlook frequently and intermittently freezes up, white screens for 30 seconds, or displays a connection reconnection notification in the lower right hand corner of the screen. The problem usually occurs when switching between calendars and mail or when trying to send an email message. We also experience slow or lagging typing in outlook. The users that report the issue have the same build, updates, and OS versions and updates installed as other users who report no issues.
We have opened a ticket with Microsoft that has gone nowhere. We have rebuilt outlook profiles, windows profiles, tried all the different channel upgrades and downgrades, eliminated public folders as being the potential culprit, compacted the OST file, changed the client to 2 months of cache, disabled IP6, ran outlook in safe mode, disabled hardware acceleration, disabled animations, disabled the downloading of shared folders, and enabled outlook logging.
It seems that if you disable hardware acceleration and animations it helps the problem occur less frequently but it does not eliminate it.
