I have the problem that I can't get email access on a smartphone. The error and informational messages are:
2023-04-24 08:00:29.448 [EAS] INFO ActiveSyncIdCache_EAS-AEVN - try to resolve active sync id "XXX" with username 'USERID' 2023-04-24 08:00:29.586 [EAS] ERROR ActiveSyncIdCache_EAS-AEVN - Mobile reported error while resolving XXX: found 2 matching devices, but should be exactly one 2023-04-24 08:00:29.965 [EAS] INFO ActiveSyncIdCache_EAS-AEVN - smc server could not resolve active sync id "XXX", next resolve will be at 2023-04-24T11:00:29.965+0200 2023-04-24 08:00:29.965 [EAS] INFO InboundHandler_EAS-AEVN - active sync id 'XXX' has permission UnknownActiveSyncId
The user himself does not have any Active Sync IDs in Exchange.
In addition to the device we are trying to connect, there is another tablet that can successfully access email.
There are a large number of people in my area who access both smartphones and tablets at the same time.
How can I approach a solution? I am thankful for every help.
