How to Reduce OST File Size in Outlook

The OST file size may decrease in case you have deleted some items. It makes the system slow and thus enhances the system’s speed and also consumes the storage space. So, instead of buying a new disk, it seems to compact Offline Storage Folders.

The moment you delete the Offline Folders Mail, it goes to the deleted items folder. The simple thing is that all the items can be recovered from the deleted item folder; it implies that still some space is consumed by OST files. The very basic fact about the OST file is that the space consumed by them is unavailable for the other uses. It makes the OST files bigger and just bigger over times and even if you delete few of the items or keep the same record in MS Outlook.
