Activesync issue - slow IOS devices but Android OK
Posted on 2016-09-18
we are noticing a major performance decrease in using mobile mail (EAS) our IOS iPhones (mostly ver 9.X).
What puzzles me is that Android phones are as happy as ever and work perfectly fast. I checked CAS and mailbox servers, cannot find anything obviuosly wrong.
What could make only IOS phones slow ? How different is the EAS implementation of IOS compared to Android ? Both CAS and Mailbox servers are 2010 SP3 version and don't seem to be having a problem.
