I'm storing a lot of contacts in Outlook and I synchronize my mobile phone with Outlook. Because of all those contacts, it is hard to find the correct one on my mobile phone and is making my mobile quite slow. Most of them I'll never use on my phone anyway.

Is there a way that I can sync only the contacts that I use the most?

I’m using iCloud with Outlook to synch my Contacts and Calendar with my iPhone and iPad. This all worked without any issues until I upgraded to Windows 10.

When I try to open my Contacts or Calendar folder, I now get the error:

The set of folders cannot be opened. The information store could not be opened.

I also no longer have the iCloud buttons on the Ribbon to Refresh, see any Notifications or Share Calendar.

How can I get iCloud to work again with Outlook on Windows 10?

We’re using Microsoft 365 Groups instead of Distribution Lists so that a history of these emails are kept in Groups in Outlook as well.

However, I noticed that Groups in Outlook only shows only up to 1 year of emails. When I look at the Microsoft 365 Group in Outlook on the Web, all the emails are shown.

I’ve set Outlook to sync all my emails but it still only shows up to 1 year for Groups. Performing a search doesn’t return any items which are available online either.

How can I configure Outlook to sync all emails from the Microsoft 365 Groups?

I have lots of contacts in Outlook and I’m switching to an Outlook.com account.

I’ve noticed that many of the advanced contact information fields that are available in Outlook are not available in the People section of an Outlook.com account.

For a couple of contacts, I’ve filled out these fields.

What will happen with the information in these fields when I move the contacts to Outlook.com?

I've configured my Outlook.com account in Outlook 2013 as an Exchange Active Sync (EAS) account.

In a previous post you mentioned that unlike Outlook Hotmail Connector accounts, which syncs on a schedule, mail for EAS accounts in Outlook 2013 should arrive almost instantly (Direct Push).

This is indeed the case for a while but when I have Outlook open for a longer period of time, my Outlook.com account stops synching with Outlook and I have to press the Send/Receive button to get my new mail or restart Outlook

How can I prevent Outlook from breaking this sync and continue to collect my email directly from the server as it arrives?
