LSUMail: Messages Per Folder Limits


 
Microsoft Advises the Following Limits on the Number of E-mails in Each Folder:

Folders Limit
Inbox 20,000
Sent Items 20,000
Deleted Items 20,000
Calendar Entries 5,000
Contacts 5,000


Why Are There Limits?

The more messages you have in the default system folders, the slower your response time and the greater the load on the mail server when trying to index your emails.
 

What Happens If I Reach These Limits?

You may be contacted by the Microsoft Online Services Team to reduce the number of items in the folder.
