I don't know if this is the final fix. In previous best practices I read that restarting archiving tasks is recommended every night - I only set EV to readonly as part of the fullbackup. Maybe I set up a regular task for that. What would you recommend?
Here is what I found on server's C: drive:
MSMAPI.DLL: 1.414.344 bytes, version 11.0.8002
mapisvc.inf: exists 2 times:
c:\windows\system32: 3962 bytes
c:\program files\common files\system\MSMAPI\1033: 17860
Have to add that this file was changed as part of a hotfix regarding attachments without file extensions.
MAPI32.dll exists 3 times (+ an evbak version)
c:\windows\system32: 1.0.2536.0, 115200 bytes
c:\program files\exchsrvr\bin, 6.5.6944.0, 634880
c:\program files\common files\system\MSMAPI\1033, 1.0.2536.0, 137816
c:\windows\system32\mapi32_evbak.dll, 6.5.6944.0, 634880
