Trio 8800 Daisy Chaining breaks Exchange calendar logon.

[Scott Schering]

We have 2 Trio 8800 devices on 5.9.0AA

Both are in Skype for Business base profile

Both have Autodiscover enabled with the url of "https://outlook.office365.com/EWS/Exchange.asmx"

Device 1 is in Hub mode and paired with a Visual Plus

Device 2 is in Device mode

Device 1 is logged into an Office 365 Skype account with mailbox in 365.

Skype logon and Calendaring works without issue as an unchained device. 

After Device 1 is chained with Device 2 we start to see the message

Warning, Failed for connect to Exchange Server. Re-enter credential to access Exchange server.

You can click details and sign in. Device 1 will sign back into exchange..

At this point you can see meetings on Device 1 but Device 2 shows Connecting...   

After a few minutes both devices will display the warning again. 

Breaking the chaining between the Trios will return device 1 to its normal function with access to the calendar. 

Device 2 configured as a stand alone non chained device will alsodisplay calendar as expeced. 

We attempted re-enabling autodiscover and https://outlook.office365.com/EWS/Exchange.asmx url on Device 2 while chained. The setting was wiped by the device after a few minutes but remained on Device 1. 

Long story short.. Trio 8800 cannot access the 365 mailbox calendar while chained with another Trio. Breaking chaining restores the calendar function.

welcome to the Poly Community.

When using Daisy Chaining no configuration is required on the 2nd or 3rd etc. unit.

Please, factory default the unit. All changes required are only needed on the main unit.

Thanks ! We had the same issue where every 10 or 15min a popup message indicated an Exchange authenticated issue. We did a factory default this morning on both units and since then so far so good. No more error message.

Thanks

There was no change in behavior. 

I will try again using a different  resource account.

Hello @Scott Schering ,

If you are not adding any configuration to the 2nd unit please open a support ticket.

In order to raise a support ticket, you need to work with your Poly reseller as they need to do this for you.

End Customers are unable to open a ticket directly with Poly support.

If this is some sort of an Internet discounter providing your MAC address or your Poly devices serial will enable us to look up who would be able to support you. This may not be who you purchased the Poly device from.

If the unit is no longer within the warranty please be prepared to Pay Per Incident / PPI. This is all outlined in detail here

Just tested with the new 5.9.0 AB Trio firmware. The calendar issue while paired has been fixed. No other changes were made and I verified the issue was still present before updating firmware.
