[AusNOG] [AUSNOG] o365 experience

[Ashley Knowles]

Hi Paul,

I was involved in migrations a few years back for some larger organisations around the 150k-200k seat mark. The user experience ultimately relies on a number of factors; as you’ve noted, network performance is a large factor, however IMO this should only be an issue on the initial migration. Properly configuring Outlook to use cached mode effectively allows you to reduce the network impact by doing an initial sync and then only syncing the changes; this can be done through Group Policy modifications.

Using a hybrid approach also works well if you have applications on premises. Ultimately routing of mail becomes the “performance” problem in this kind of situation.

Feel free to reach out directly if you have any specific queries.

Cheers,
Ashley

I'd be interested to hear general opinions and lessons learned from o365 migrations. So far as I've seen, the architecture (network and services) is complex, and user experience can never equal local Exchange.

So much so it leaves me wondering if the effort of migration can be justified? At the end of the day, you need a performant service, not finger pointing between networks and services, and blaming performance on insufficient network/proxy scale out.

Kind Regards

Paul Wilkins
