I am facing a weird issue with SBS 2003 (windows server 2003 sp2 with microsoft exchange 2003 sp2) Microsoft Exchange ActiveSync. ActiveSync users are able to configure the devices just fine, send and receive email fine as well but when they try to send any attachment the email will stay in the outbox.
So far i have tried the following fixes
made sure the permissions on the exchange vdirs and activesync vdir are correct
c:\windows\temp and %temp% location has read/write access to authenticated users
uploadreadaheadsize (thru adsutil.vbs) and messagesizelimit for oma reg key are bumped up (20MB each)
testremoteexchange connectivity analyzer shows all green
Now, if i make user the member of administrators group and try to send an email with attachment (i am sending a screenshot of 2.3mb) it goes out fine.
IIS logs shows HttpServerStatusError 500used logparserstudio to parse the iis file
cs-username cs-uri-stem HTTPstatus w3-status-details
domain\testas /Microsoft-Server-ActiveSync 500 HttpStatusServerError
any pointers how this issue can be dealt with and resolved, will be appreciated.
