hi all,
We are in project upgrading from exchange 2007 to 2013. everything is ok but iPhones download all the messages again and again from the first mail to last one.
it occures frequently, for example 3 times in a day or over 3 times.
There is no problem on users we moved to Exchange 2013 but on Exchange 2007 users frequently downloads messages again and again, 3-4-5 times in a day.
does anyone experienced this?
thanks alot.
