Outlook hosted exchange,
I am having a major problem with my best cliend who is using office 365 on a hosted exchange platform. the have another 25/30 mail boxes with no problems.
When the client tries tp open outlook it takes 3 or 4 minuites to lodad and often wont open.
Also if he tries to ope3n a saved outlook message it wont open and crashes.
I have reinstalled outlook several times, fitted a new HDD and reinstalled windows and even tried a differend PC.
I have also done a scan.pst on the ost file.
the only thing I have not tried is to disable cashed exchange mode.
Any help would be appreciated.
