Logged in to a polycom trio 8800 in SfbO but unable to sync exchange online calendar. After pulling logs I see the following error. Polycom Trio has already been updated to latest firmware (188.8.131.5206). Only other forum posts I could find on this was for MFA being enabled. Checked user accounts in O365 tenant and it is currently disabled. At this point I'm at a loss for what else to look for. Logs below, any help would be greatly appreciated!
Error: |[CAuthServiceEwsAutoDiscRsp::execute] Failed to get oAuth token with (400,Failed to Get UT)
welcome to the Polycom Community.
Both the community's Must Read First and the community's FAQ reference the basic minimum information a new or follow up post should contain.
This ensures the questions having to be asked are limited and any new or follow up post contains the right amount of details to ensure any voluntary participant within the community does not spend additional time chasing basic information.
As a reminder the basic information asked for:
UC Software 4.0.0 or later via the Web Interface Utilities > Phone Backup & Restore > Phone Backup > Phone Backup
Whilst providing some of these details may not directly impact any possible answer the community can provide, it does enable Polycom to have an overview of the current software used. In addition other details allow us to check logs or look up a potential support partners if an issue needs to come into support. It also enables us to verify the entitlement for using features.
Please ensure you always check the FAQ's and/or utilize the community search before posting any new topics or follow up post’s.
Looking at your log I assume this is a firewall issue:
1113113454|pgui |4|00|[EWS AutoDiscover] Fetching DP OAuth token for URL 'https://outlook.office365.com/autodiscover/autodiscover.xml' 1113113454|auth |4|00|eReqRspID HttpCode message
Not having provided all the relevant data also makes me worry about these:
1113113439|copy |4|00|SSL_connect error Peer certificate cannot be authenticated with known CA certificates.
I suggest you get your network team to check the firewall.

If this all fails please open a ticket via Polycom support.
In order to raise a support ticket you need to work with your Polycom reseller as they need to do this for you.
