This is the second time a user has a problem to archive over100-200 mails.
When he selects 5-10 mails he can archive without any problem.
The moment he selects over 100 mails ( I don't know the exact number it can be 150 or 200) the well known error message appears:
Cannot archive.......Would you like to change the archive settings? (Yes/No)
Is there a limit for the numbers of mails can be archived at the same time?
