The “Sign in as Different User” option that was present in SharePoint 2010 has now been removed for SharePoint 2013 (I assume because it caused a lot of confusion between Internet Explorer and Office if you were logged onto the PC under one account and into SharePoint as another).
You can get around this by visiting http://siteurl/_layouts/closeConnection.aspx?loginasanotheruser=true
Oddly, within SharePoint 2010 at least, when you connect a calendar to Outlook it will not synchronise the category information for the event. It seems that Outlook uses a field named Categories to store this information and SharePoint uses Category.
Although not ideal, we can resolve the issue by visiting the List Settings page for the calendar, opening the Event content type and adding Categories from the list of pre-existing columns.
When working with calculated fields within SharePoint, there isn’t an inbuilt function that will allow you to add a specific number of hours to a date. You have to stop of a second and think about it – and the solution is quite simple.
While adding whole days is as simple as =[DateColumn]+5, to add hours you have to break things down. So to add eight hours…

Another PowerShell command to note for future reference. Within my SharePoint farm there is often a need to migrate a user for one reason or another, e.g. their username may have changed. The Move-SPUser cmdlet migrates user access from one domain user account to another. If an entry for the new login name already exists, the entry is marked for deletion to make way for the migration.
Note to self: When setting permissions and sharing content stored within SharePoint 2013, Microsoft have now hidden the “All Authenticated Users” option that was present in 2010. To get around this, just type “NT AUTHORITY\AUTHENTICATED USERS” and click the Share button.
Every so often I receive a helpdesk call from a user who, although their account is a member of the SharePoint site’s Owners, Members or Visitors group, is still presented with the generic “Access Denied” page when they attempt to visit the site.
After a bit of Googling, I found this post that seemed to have the answer.
The trick is to flush the user’s access permissions and recreate them. This can be done by:
Remove the user’s account from the SharePoint group.
Add the account into the Site Collection Administrators group (Site Actions > Site Settings > Site collection administrators).
Remove the account from the Site Collection Administrators group.
Add the account back into the original SharePoint group.
