Other limits include 10 GB per individual file, 10,000 total files, and 200 folders. No error is displayed, but the resulting ZIP file will have three items: the folder that is being downloaded, a similarly named folder, and a `__All_Errors.txt` file.

When 'New Outlook' in Outlook for Mac is turned on, features are missing or not working correctly.	A number of features are not yet available in the 'New Outlook' interface. For details, see The new Outlook for Mac.	Toggle off New Outlook in the Outlook menu bar.	Known issue	November 6, 2020
On files synced with Microsoft OneDrive at IU and Microsoft Teams at IU via a client, the 'last updated' timestamp may not be reliable within a file explorer.	Because of the way that OneDrive and some other sync clients sync and upload files, the 'last updated' timestamp on a file synced to OneDrive may be inaccurate when viewed with a local file explorer. The timestamp in the web portal is accurate, though.	If you need to track the 'last updated' time of a file, use the web portal or another tracking method, rather than relying on the time stamps that appear in the file explorer.	Known issue	October 15, 2020
When sharing files from Microsoft OneDrive at IU, email notifications about the share will not be sent to the recipient of the invitation if the sender is on Exchange 2013.	Because OneDrive utilizes Exchange Online to send email notifications about files shared in OneDrive, if the user sharing files has an Exchange account on Exchange 2013, an email notification will not be sent to the recipient of the sharing invitation. The permissions to the file or folder will still be added for the recipient.	This is no longer an issue once a user has been migrated to Exchange Online.	Known issue	August 6, 2020

Known issue	June 16, 2016
