Exchange 2010 is definitely very old software now and you would have a much better experience if you run Exchange 2016 CU3 or above. Why that release? Because it includes a new version of Autodiscover that is used by services like Teams.

Generally, Office 365 is not super-sympathetic to old software, be it old clients or old on-premises servers. You invariably have a better experience when clients are Office 2016 (or click to run) and the on-premises environment runs the latest servers. This is critical when you think about it if you want to run hybrid for any length of time because your on-premises platform has to stay aligned with the cloud platform - and the cloud platform moves fast.

If you can't upgrade to Exchange 2016, get all mailboxes to Office 365 ASAP...
