[horde] Latest Gmail app / Android update seems to break ActiveSync with Horde

[Pascal Rigaux]

Hi,

We're having issues too :'-(

« Find not supported » may not be the culprit since this error was already occurring one year ago.

> Just a heads up that latest Android and/or Gmail app update seems to break ActiveSync connection to Horde. I have reports so far of 4 phones of different brands - Samsung and Xiaomi - on Android 12 and 16 respectively - which have all developed similar symptoms in the last week or so. They are connected to 2 different Horde instances - both on version 5.2.21. The emails and contacts endlessly reload again and again. I have tried to clear the cache and storage for the Gmail app. Also deleted and reconfigured the accounts on the phone. The main error message I can find in the Horde logs is the one below - which might or might not be connected to this:
