Office 365 - SharePoint Online Improves Limits and Makes It Easier to Restore Documents

Based on feedback and reports on how customers use the service, Microsoft made the following improvements to SharePoint Online:

Improved file upload experience
  • Increased file upload limit from 250MB to 2 GB
  • Expanded support for a broader range of file types: SharePoint Online now accepts a broader range of file types, specifically .exe and .dll. 
Uploading large files into SkyDrive Pro (applicable to team site document libraries as well); files were dragged and dropped from the desktop into the Web interface.
See SharePoint Online blocked file type list.
 Increased Site collection and list look-up limits
  • Increased site collection limit from 3,000 to 10,000 
  • List look-up threshold increased to 12 look-ups.
*Note: this increase only applies to Office 365 Enterprise plans (including Education and Government) - Office 365 Small Business and Midsize Business remain at a single site collection and twenty site collections respectively.
Review the list of all SharePoint Online boundaries and limitations. 
Improved self-restoration
  • Increasing recycle bin retention duration (from 30-90 days)
  • Turning versioning on by default for new SkyDrive Pro libraries with 10 versions being retained.

  • All above announcements apply to all Office 365 business plans - except the 10,000 site collection increase (only applicable to Office 365 Enterprise plans (including Education and Government).
  • Does not apply to Office 365 Home Premium offering, which combines the latest Office applications with Skype and SkyDrive storage.
  • Office 365 dedicated plans are not receiving this same update, because they are managed in a unique, isolated infrastructure.
  • SharePoint will not execute any arbitrary EXEs or DLLs uploaded by a user to a team site or to their SkyDrive Pro.
    1. SharePoint will only accept uploads from authenticated users reducing risks that an outside attacker could post any malicious files.
    2. SharePoint has an antivirus scanning engine built in to detect malicious files.
    3. If user's attempt to execute a malicious file in their synced folders, Outlook and Windows have warning pop-up dialogs requesting consent from the user before the malicious file can execute.
    4. Many users also have antivirus scanning applications on their client computers and therefore would detect and quarantine any malicious files.
    5. Finally, should admins have cause to worry about these scenarios, they can enable auditing to any document library to detect which end user initially uploaded the malicious file.
